Since then, hundreds of people have flocked to Brazos Bend State Park, an hour's drive southwest from downtown Houston, Texas, each Saturday evening to admire the facility and the stellar views it provides. The 1.2 million dollar George Observatory is largely funded by a $770,000 grant from the George Foundation of Fort Bend County. Its central 36-foot dome houses a 36" research-grade Ritchey-Chretien purchased from Louisiana State University for $150,000. The 12-ton telescope is a twin of an instrument at Kitt Peak National Observatory. Included in the price-tag are a spectrograph, a plate camera, and an off-axis guider, as well as a hydraulic floor. Flanking the major dome are two smaller domes which serve the amateur community and researchers when not in use for public nights. The realization of this project has been a truly cooperative effort among many of those involved in astronomy in the Houston area. Dr. Reginald Dufour of Rice University assisted in the acquisition of the telescope and continues to oversee the scheduling of the 36". The Museum has involved the members of several Houston-area organizations, including the Houston Astronomical Society, the Fort Bend Astronomy Club, and the Johnson Space Center Astronomical Society, from the initial planning excursions to LSU to the current staffing and maintenance of the facility. Indeed, Mat Shapiro, the project manager, is a local amateur astronomer. In return for our efforts, volunteers will have use of the observatory for research projects during the week and for viewing after the public has departed at 10:00 p. m. on weekend evenings. The Fort Bend Astronomy Club has also raised $24,000.00 for the East Dome and is in the process of raising funds for a club telescope to be housed there. On my first visit to the George Observatory on October 14 for Astronomy Day, I was immediately struck by the stunning architecture designed by Fluor Daniel. The telescope domes are perched on top of a lower level housing a lecture hall, permanent ecology and astronomy exhibits, and storage areas. To help minimize thermal disturbances at night, 10,000 cubic yards of dirt gently slope up the lower level on either side of the main entrance, turning it into an artificial basement reminiscent of the "earth houses" that can be found in the North. This design puts the telescopes high above the trees and any ground fog that may develop. Special paint for the dome also helps moderate thermal differences. Getting to the telescope is easy. A red-lit trail leads one from the parking lot over alligator-filled Creekfield Lake to the building. The official golf cart transports bulky portable telescopes, equipment, and infirm visitors. Brazos Bend's location south of Houston is not conducive to good views of the northern sky, but the southern sky is excellent, with only farmland and the Gulf of Mexico between the park and the Milky Way. A typical public night begins with solar observing in the afternoon followed by views through numerous portable telescopes as well as those mounted in the domes. It was a delight to hear the oohs and ahs of those who came to view the Houston-sized brilliant lunar crater Aristarchus through a C-11 on a near full moonlit night. The George Observatory opens up entirely new possibilities for real astronomy only a short distance from an otherwise astronomically hostile environment. An Ultimate Fund-Raiser Don A. Edwards, Fort Bend (TX) Astronomy Club In late 1988, the Houston Museum of Natural Science determined that the monies budgeted for their new George Observatory would be insufficient to build the entire complex as originally planned. One of the first things to go was an "ampi-theater" area adjacent to the Observatory. When this cut was also insufficient, it appeared that the two adjoining small observatory domes (3-4 meter, each) would have to be deleted. Instead, the Museum asked for assistance from the local astronomy clubs, as well as from interested individuals. The 3-meter West Dome was almost totally funded by an individual contribution. And in February, 1989, the Fort Bend Astronomy Club accepted the challenge to raise the funds for a 4-meter East Dome and also to purchase a telescope to be placed in the dome. The dome would be the property of the Museum/Observatory. The scope would be the property of the Club, but would be available for public viewing each Saturday night. It would also be available to amateur astronomers on other nights. The Club would provide an operator for the scope and the dome. The $24,000 that the Museum needed for the East Dome was raised or pledged by late summer through donations by individual club members, and by various fund raising activities such as a swap meet, bake sale, car wash, raffles, etc. Now came the task of funding a scope to put in the dome. The club wanted a 16-inch Schmidt-Cassegrain which would cost $15,000. Through the sale of club t-shirts, caps, coats, etc., and through a raffle for which approximately 50 prizes were donated, the club had made a good start by mid-fall. Then FBAC president, Dennis Zwicky, who owns a local astronomy shop, was able to make arrangements with Celestron to obtain one of the first Ultima-11 scopes shipped. The Ultima-11 would replace the 8-inch CAT temporarily in the dome, and with this public exposure, as well as word-of-mouth, we would sell raffle tickets on it. We decided on the following plan for selling the raffle tickets: a) limit the total number of tickets so each purchaser would know the odds on each ticket (600 to keep the chances "reasonable"); b) no limit to any individual, since the odds on any one ticket would be the same regardless of the number of purchasers; and c) $10 per ticket for 600 tickets to raise $6000. We also decided to keep the number of tickets small to make sure we could sell them all. We have just started to sell tickets and will continue until all 600 are sold. At that time, we will have the drawing. If the first group goes well, and there seems to be more interest, we will do it again. To buy a ticket, write Don A.

A Newtonian View of the Astronomical League Ed Flaspoehler, REFLECTOR Editor Every three months you receive your copy of the REFLECTOR, and after a quick look through, you ask yourself, "Why isn't there anything in here about my club? It always seems to be somebody else's?" Or, "Why do they have all that stuff about Texas, when I live up here in Idaho?" Or, "Who cares about all that club gossip? I just want to read about technical things?" Well, this is the main problem that the editor of the REFLECTOR faces, how to please all of the people all of the time. To take first things first, I think I should tell you where all those articles in the REFLECTOR come from. Can you guess? It's your club's own newsletter. Each month, I receive from 20 to 30 newsletters from all over the country. I read through them looking for articles that I think will be of interest to the most people. Generally, I hope that, since I am an amateur astronomer too, what is of interest to me will also be of interest to you. There is an incredible variety of information out there in your newsletters, ranging from advanced observational techniques and reports to bad poetry (just kidding!) and heavenly cake recipes. There is also an amazing amount of club gossip, which in itself makes for interesting, if voluminous, reading. Most of this material is not really suitable for reprinting for a readership of 11,000 amateurs all over the country. But a lot of it is. So how do I pick out what you read? First of all, I look for well written articles on interesting topics. Glance through this issue and you will find articles on new observatories, computer software, observing techniques and craft projects, not to mention club fund-raisers and convention reports. This is just the stuff I wanted to put in. There is also the required material like ALCON notices, League sales, officers list, and so on. But if it looks good, I try to print it. So why did your club not get mentioned? Most likely it is because your club did not send me its newsletter. I already get about 30 newsletters, but there are 178 clubs in the Astronomical League. So far, 148 have not taken the time to put me on their mailing list. Tell your ALCOR to make sure the REFLECTOR editor gets a copy of his publication. (I think I'm about to be inundated!) And if you are willing to spend the money, keep Barlow Pepin on the list too, since he is assistant editor. "So what," you say, "I don't want to read all that club gossip anyway. I only want to read the heavy Astronomy stuff." Well, here we get into a discussion of the purpose of the REFLECTOR. I think the magazine is perfectly named, and not after a Newtonian telescope either. The REFLECTOR is just that, a vehicle through which the activities of each part of the League are reflected back to all the League. Some of these activities are scientific, but there is a lot of socializing going on out there too. After all, when was the last time you went to a star party and didn't get your observing done because you were gabbing with your friends? I feel that it is the responsibility of the REFLECTOR to cover all League activities, not just the technical ones. There are bigger and better publications than this to cover the scientific details of Astronomy. The telescope simile is probably apt for another reason, too. Just as a telescope can look at only one narrow field of view at any one time, so the REFLECTOR can highlight only part of the League in each issue. It took me almost two years of concentrated effort to look at every object on Charles Messier's list. Just so, the REFLECTOR can cover the activities of the League only over an extended period of time. I hope I have explained a bit about how I, as a new editor, view my job. It's both fun and a challenge. I plan to make the REFLECTOR as attractive and interesting as I can as I continue to learn more about how to put together a newsletter. I can do that only with your help and input. Clear skies, and good observing. The International Dark-Sky Association Tim Hunter, President, IDA Almost all amateur astronomers have been bothered by unwanted, obtrusive light. Probably the problem had to do either with light trespass (spill light from a neighbor's yard or a street light), glare (a bright, direct light close by), or urban sky glow (the pall of light hanging over most cities). These are major problems with no quick, easy solutions, especially urban sky glow. Yet they can be solved if enough effort is devoted to the problem. Here is a brief outline of some specific things you can do: 1. Talk to the offender. Ask for their help. Be friendly but persistent. Constantly push without making enemies. 2. Educate people as to what can be done. Learn about quality lighting. The goal is not to fight nighttime lighting but to insist it be designed for the task and be of high quality. 3. Learn about the adverse problems of poor lighting: glare, clutter, confusion, light trespass, energy waste and sky glow. Set a good example yourself at home and at your place of business. 4. Join IDA as an individual member to receive more detailed information and to support the cause internationally. Individual membership is $20 per year. 5. Talk to people individually and in groups. Work for local lighting codes. You can write to IDA for specific details concerning good lighting ordinances. 6. Learn the elements of good outdoor lighting: full cut-off shielding, lowest wattage necessary for the task, timers, and motion sensors where applicable. In coming issues of THE REFLECTOR these ideas will be explored in more detail. Remember, dark skies are compatible with quality lighting. In fact, they require it. IDA Annual Meeting IDA'S 2nd Annual Meeting will be held on the week-end of Saturday April 7 and Sunday April 8, 1990 in Tucson, AZ, at the Hotel Park. The tentative schedule includes a scientific meeting devoted to light pollution, space debris, and radio pollution on Saturday afternoon, a banquet that night, and a business meeting Sunday morning. All interested persons are invited to attend. There will be a $10 registration fee for the meeting and an additional $20 charge for the banquet dinner. There will also be informal lunches, a social hour and possible tours to astronomical places of interest in the Tucson area. Write to IDA for information and to sign up for attendance. The International Dark-Sky Association, 3545 N. Stewart Ave., Tucson, AZ 85716 VOYAGER "The lnteractive Desktop Planetarium" for Apple Macintosh Computers Produced by: Caina Software 830 Williams Street San Leandro, CA 94577 Price: $99.00 (800K disk and 85 pp. manual) I've been using VOYAGER for several months now and I am stiIl finding more and more practical uses for it. The program contains three very different views of the sky, the Local View, Star Charts, and a Celestial Sphere which shows an entire hemisphere at once. The Local View, which I use most, shows you the horizon and sky from any point on earth. Enter your location (latitude and longitude) through one of the pull-down menus and the program retains it in memory until you change it. Pick a day and time and the sky is displayed in a few seconds. The program is set to the computer's internal clock and will rotate the sky on command at any reasonable time interval. The default setting is sidereal rotation. The 9100 Yale Bright Stars in the display are realistically displayed in whole-magnitude bins in white on black. They can be reversed to negative (handy for printing) with one click of the mouse. Magnitude limits can easily be changed to unclutter the sky. Deep sky objects, either Messier or a combination of Messier and NGC objects, are displayed with legible symbols. You can pan around the horizon or look up toward the zenith at your location simply by using the horizontal and vertical scroll bars. The positions of all planets, inducing the outer three, are shown when present, and information on any non-stellar object or planet is displayed by clicking on the display with the mouse. Each star in the display can be selected; the catalogue includes all the standard star data. In addition, VOYAGER contains the Arabic name when one is known, notes on very interesting stars, and RA and Dec as well as altitude and azimuth for the minute chosen. (Dobsonian users take note!) There is also an option which marks all doubles or variables. Celestial coordinate grids can be overlaid by selecting from the sidebar menu, which also offers constellation outlines along with ADD or REMOVE commands for the planets and deep sky objects. There is also a ZOOM feature which allows you to choose six closer views of the center of the screen. Any object can be centered by choosing a FIND AND CENTER menu option and typing in the name of the object, or clicking on the object for information and then choosing the option. Set VOYAGER to start around sunset and select a fast rotation rate. You can then watch the sun set and note the positions of any planets visible, and check the rise, transit and set times of any interesting objects, including the moon. Constellations and major deep sky objects can be checked for any time of night in a few seconds. And this program is FAST. The entire sky is rearranged in a few seconds, no matter how great the change. It is a great way to plan an observing session. The other main sky form shows star charts in accurate projections, containing all the information found in an atlas like Norton's but with the advantage of no fixed borders or pages. The viewer can simply scroll to any RA and DEC position and the program will show a chart centered on that point. In either mode, you get what you see when you do a PRINT SCREEN command. Charts or local views can be printed with or without selected object information, depending on how you ask. The planetary database is fairly awesome, and the ability of the program to show you orbits of planets, Jovian satellites, and selected comets and asteroids from any spot in the solar system relative to the sun is something that astrophysics buffs will really appreciate. If you enter the classic orbital elements of any known (or fantasy) object, VOYAGER will put the object on-screen and show you the orbit around the sun at your chosen speed, with all the planets displayed as well. The TRACKING function draws paths for any object chosen, and any graphic so created can be printed as well. This cloudy-night bonus is one that I haven't fully explored yet, but the occultation of 28 Sagittarii by Saturn was something I found by zooming in and playing with times. This function is not even mentioned in the otherwise well-written and in-depth manual. I'm sure the authors really didn't think of doing this type of look-up when the program was developed; it is testimony to the accuracy of the plotting that this event shows clearly in the graphic display. VOYAGER is the best practical observing aid I have ever used. Any amateur astronomer with a Macintosh Plus or higher will find it to be an excellent, fast program with a multi-role configuration, and well worth the price. M. Barlow Pepin - Assistant Editor The E-Z Scope Simplified Merry and Wayne Wooten, Escambia (FL) Amateur Astronomy Association We believe every kid should own a telescope - a good one with achromatic objectives and eyepieces. But most parents are not ready to put out real money for a kid who isn't really sure he is into astronomy yet. We also think the kid will enjoy the scope more if he builds it himself, so it needs to be simple and kidproof. For the Marine Science/Astronomy Institute that Merry and I taught at Pensacola Junior College and Ft. Pickens this fall, we revisited our old copyscope designs and made up this starter kit. It uses a JML 5.4" f/4.5 copy lens, available in lots of 10 from JerryCo for $3.75 each (or $4.75 individually). Order item 2702, the Fax-Kowa Lens, from JerryCo. The Fax-Kowa objective has a clear aperture of about 30mm, thus gathering about 25x as much light as your eye, and giving about 5x better resolution than your eye can. In their new catalog, JerryCo also has what sounds like an ideal eyepiece for this scope, a 19mm focal length Magnavox lens for only $3.50; order item 6918. C&H Sales recently began stocking surplus Olympus microfilm lenses in a variety of focal lengths that make good eyepieces for Japanese refractors as well as copy scopes. We especially liked OL 9858, a 14.18mm eyepiece that gives about l0x, and OL 8953, a 26mm lens giving about 5x. They have a total of ten different lenses in varying focal lengths, all for only $6 each. Stock up while the supply lasts. To assemble your E-Z Scope, cut a 3-inch long piece of 2-inch PVC pipe. Make sure both ends are cut as square as possible. Neatly wrap 3/4-inch masking tape around the bottom of the copy lens until you match the 2-inch PVC's diameter, then wrap two or three turns of 1.5-inch masking tape around both lens and PVC pipe. For the sliding focuser, use a 1-1/4-inch male adapter (Scotty's 694-158, $.49), wrapping 1.5-inch tape around the large end until you have the focuser sliding snugly inside of the other end of the 2-inch PVC tube. It is best to make a 1.25-inch tube for your eyepiece, so it will later be standard size for use in all telescopes. Cut off the bottom of a black Kodak 35mm film canister, and wrap 3/4-inch masking tape around the bottom of the desired eyepiece until it fits snugly inside the canister. You will probably need a piece of masking tape on the inside of the adapter to get the film canister to focus smoothly. You may tap the PVC about 1 inch up from the copy lens with a 1/4x20 hole for attaching the E-Z Scope to a camera tripod.

Gordon, Lehigh Vallay (PA) Amateur Astronomical Society In 1987 Astronomy magazine conducted a marketing survey of its paid readership, which at that time totaled 155,000. The results of their efforts are informative and of enough significance that I thought they should be shared. Sample errors of these data range from 0.6% to 3% according to Astronomy. The average Astronomy reader is 36 years old and 90% are male. Over 80% have attended or graduated from college. Over 32% are aged 25-34, while over 27% are aged 35-44. Thirteen percent are aged 45-54, but less than 8% are in the 18-24 year category. Total household income was 44% in the $25-50,000 bracket and 21% in the $50-75,000. Less than 12% had incomes from $15-25,000. The average household income from all groups was over $50,000. Statistics for Sky and Telescope are strikingly similar since over 55% of its 90,000 readership also receives Astronomy. Astronomy discovered that 74% of their readers owned telescopes, with almost 35% of this total being refractors, 30% Newtonian reflectors and 24% catadioptrics. 52% of these Instruments had apertures 4 inches or less and nearly 45% of the telescopes were in the range of 5 inches to 11 inches. Less than 4% of the respondents owned instruments larger than 11 inches. These are very intriguing results. They show that the refractor is still king, with the Newtonian reflector close behind. Catadioptrics are a distant third in the race. It also gives credence to the fact that despite the enormous publicity given to larger apertures, smaller telescopes of 4 inches or less are still the number one choice in the amateur astronomy community. When the midsize aperture range is included, these two categories swamp the "aperture happy" crowd who extol the value of size for its own sake. Disturbingly, the survey also found that less than 13% of Astronomy's readership belonged to any organized club or group. What can be gleaned from this readership profile? First, the average amateur astronomer is overwhelmingly male and is in his late 30's to early 40's. Household income is about $20,000 higher than the national average, which was about $30,000 in 1987. Second, very few young people read Astronomy, which ironically is geared more to the general public than Sky and Telescope. Third, there appears to be little support for organized astronomical activities. Fourth, the small to medium aperture instruments are still the overwhelming favorites, with refractors still leading the group. There are some interesting geographical factors also. New York, New Jersey, and Pennsylvania, with over 16.24% of the country's population, have only 15.4% of Astronomy's readership. Alaska, Washington, Oregon, California, and Hawaii, on the other hand, with only 14.04% of the national census, have almost 21% of Astronomy magazine's subscribers. These populous, northeastern states are clearly non-astronomical, despite several fine amateur societies and numerous professional astronomical institutions. For example, Pennsylvania's total Astronomy subscriptions and over-the-counter sales in 1987 was 6478. Its population was 11 million. California, with a little over twice the population, had almost 3-1/2 times the readership (21,381). I believe that it will be a real challenge to amateur astronomical groups to maintain their present numbers. In the future, it may be the membership chairperson or committee which holds dominance over the survival of an organization. Publicity about astronomy may have to be an ongoing activity rather than just a flurry around a space spectacular or major astronomical event. I have often said in the past that many amateur societies are having difficulty recruiting new members, younger members in particular. The lifeblood of any group is its ability to replace individuals who pass away, move, or simply lose interest. There is a vast, untapped reservoir of potential club members out there. Potential recruitment of new members will have to come from those groups whose household incomes and educational levels are well above average. Less effort should be spent on obtaining new members from the general population. Perhaps we should specifically invite the management of major corporations in our area to our functions as well as the general public. There is some real food for thought in Astronomy's latest reader survey. How we digest this information may very well spell our future health as a viable organization. Things I Learned While Herscheling David Hasenauer, Texas Astronomical Society of Dallas I recently completed the Astronomical League's Herschel 400 observing project and thought I might share some of the things I learned along the way. If you are planning on tackling a "formal" observing program such as the Messier list or the Herschel 400 list, a little advanced prepartion can help a lot. When I started the Herschel list, I simply worked my way through the A.L.'s guide numerically via the object's ascending Right Ascension. However, Randy Lambert, another Herschel certificate holder, made a suggestion which made my observing sessions a lot more efficient. He circled all 400 Herschel objects on his Tirion 2000 atlas and filled in each circle after making an observation. I modified this technique a little and simply erased the circle after I logged the object. Spending a little time with pencil and atlas can allow you to log twice as many objects during an evening while still spending the same amount of time on each one! The only finder on my 17.5" Dobsonian is a Telrad. (If you only have one finder, make it a Telrad). If you place a pair of 7x50 binoculars so that one half is pointed looking through the Telrad, you end up with a beautiful red bulls-eye pattern suspended in a 7x magnified star field! The star field orientation is erect, so star hopping is quite easy. The Herschel 400 list includes 230 galaxies, 104 open clusters, 34 globular clusters, 24 planetary nebulae, and 8 diffuse nebulae. With such an assembly of objects to look at, I learned that different celestial objects often benefited from different observing techniques. For example, open clusters that are located in the Milky Way band can sometimes be difficult to separate from the backgound star field, especially with a large aperture telescope. I occasionally would do some mid-week observing closer to Dallas, and I found that, suprisingly, the brighter light dome actually helped some of the open clusters to stand out better compared to their appearance from a "dark sky" site. I found that planetaries can take on very different characters depending on the magnification you use. The best example of this on the Herschel list was NGC 2392, the Eskimo Nebula in Gemini. At 230x there was very little detail in a fairly round, whitish shell. At 400x the shell separated into two concentric shells with visible brightness mottling across the object. There is no denying that the amount of detail you can see is strongly affected by your telescope aperture, but whatever size scope you have, try different magnifications. Galaxies and nebulae are best viewed under skies with excellent transparency. At the Texas Star Party in 1988, I was suprised at how the detail in a galaxy could be adversely affected by a slight, but noticible reduction in the transparency from one night to another. Pursuing a "formal" observing program really will improve your observing skills. I was very suprised by the difference in quality and detail of some of my early Herschel observations relative to my later ones. About half way through the list, I took the time to determine the actual angular field of view of one of my favorite eyepieces. This allowed me to make rough size estimates of the various objects. A good star atlas is indespensible for anyone pursuing an observing program. For those of you working through the Messier list who are intimidated by the Virgo Cluster, I strongly recommend the Edmund Mag. 6 Star Atlas. There is a blow-up of the Virgo region, as well as the Orion and Sagitarius regions, which makes the task a lot easier. For those of you Herscheling, the Uranometria is almost a necessity. I found that while working through the Virgo Cluster with my large aperture scope, I could actually "galaxy hop" (as opposed to star hop) with the aid of that atlas. The Tirion atlas often does not have enough detail to allow you to confirm an observation, especially in a rich galaxy field. If you use the Telrad trick mentioned above, you'll find that the limiting magnitude in the Uranometria corresponds rather well to the limiting magnitude visible in 7x50 binoculars. This makes star hopping a snap! For those of you with computers who avoid "formal" observing because you cannot keep legible observation notes, fear not. Weems Hutto wrote an excellent DBASE program that will allow you to record your Messier and Herschel observations on your computer. If your computer is equipped with a modem, you can download the program from the Astronomical League's StarGate BBS, (214) 578-7618. Weems' program is called OBSERVE.ARC. I hope this potpourri of hints, tricks, and comments are useful. I strongly recommend a "formal" observing program as a way to improve your skill and achieve a tremendous sense of satisfaction. Good luck and clear skies. Expansion of Herschel Club Activities Brenda Branchett, AL Herschel Coordinator Activities of the Herschel Club at this time include a possible expansion of the current 400 object observing list. Dave Branchett and I are observing additional Herschel objects and have almost reached another 400 objects. We want to get a preliminary list out to those interested as soon as possible and change the coordinates in the current booklet for year 2,000 when it is ready to be reprinted. Dave and I can get a simple preliminary listing out for anyone wishing to continue with the Herschel project after observing 400 objects. The League is still considering the possibility of issuing another certificate on completing 800 objects. We are also considering using the same certificate we use now, only adding a notation that 800 objects have been completed. There were originally 100 Herschel Certificates printed in 1980. We have awarded over 50 certificates. It appears we are receiving a higher number per year of amateurs sending in their observations to me for verification than in the beginning, so I feel that within the next two to three years, we will need additional certificates printed. At that time, we might want to change it for the additional objects observed.

Loflin II 5-11-89 Mark Swanson 5-11-89 Doug Kniffen 7-4-89 The Messier Club The Messier Club is the primary observing award program of the Astronomical league. If you are interested in joining the Messier Club, briefly, here is what you must do. 1. You must belong to a club or society which is currently affiliated with the Astronomical League or be a member-at-large of the League. 2. You must find and observe the required number of Messier objects. Observations of 70 or more objects will qualify you for regular membership. Observations of all 110 of the Messier objects qualify you for honorary membership. 3. You must keep a log book with information about the size and type of instrument used, power used, time of observation, seeing conditions, and a description of how the object looked to you. 4. After you complete the above, have any official in your local society verify your observations and send a letter of verification to the Astronomical League Messier Club chairperson. If you are a member-at-large of the League, you should send a non-returnable copy of your log book. A copy of the log book is not needed when a letter of verification is sent by your local society. The Astronomical League's publication OBSERVE: A guide to the Messier Objects is highly recommended because it includes a description of the objects, hints on starhopping to the objects, and a logbook section.

Prentice Dr. Aurora, CO 80015 (303) 680-6894 A Badly Overlooked League Service It is an unfortunate fact that only about 2% of the League members attend the National Conventions. Geography is the main impediment. It doesn't have to be entirely this way. The best part of each convention are the speakers and the information they provide, which is substantially available to you in the form of the annual PROCEEDINGS. All you have to do is write for a copy. The content of the PROCEEDINGS is both of excellent quality and largely slanted for the amateur astronomer. The speakers from within the League and invited speakers have gone to a lot of trouble to prepare information they think will be of interest and value to you. The 1989 PROCEEDINGS, for example, has articles on training the eye for deep sky observing, drawing at the telescope made easy, how to find novae with binoculars, aids on how to observe Messier and Herschel objects and the latest on the spin-cast process which extends the size limits for large mirrors. The 1988 PROCEEDINGS contained hints for doing better astro-photography and how to participate in cooperative scientific discussions, as well as input from ALPO, which participated in the convention that year. A few copies of these past issues are still available at reduced prices and can be ordered through the League Sales. You can now order a copy of the PROCEEDINGS for ALCON 90 when you send in your registration form. But even if you don't plan to attend the convention, you can still order your copy by sending a $6.00 payment to the convention chairman. The PROCEEDINGS will be sent to you postpaid less than two months after the convention.

The NERAL business meeting was conducted by Chairman Gregory Bohemier and Regional Representative Betty Hasson, and included the election of officers for the coming year. Bohemier and Mary Carol Lindbloom were elected co-chairpersons of NERAL, while other elected officers included: Jack Megas, vice chairman; Jack Welch, treasurer; Richard Sanderson, secretary; Betty Hasson, regional representative. Richard Sanderson presented an update on the NERAL 1990 convention, which will be hosted jointly by the Amherst Area Amateur Astronomers Association and the Springfield Stars Club. The tentative location is Amherst College in Amherst, MA, which is the home of a planetarium and an 18-inch Clark refractor. Sanderson stressed that this will be an independent convention for NERAL, rather than a joint meeting, which has happened much too often in recent years. The 1989 Astronomers' Conjunction/NERAL Convention featured papers on a wide variety of topics including the oldest American-made planetarium, the 1991 total eclipse, sunspots, the Bighorn Medicine Wheel, and the Great 1989 Aurora. David Kelly, whose 6-inch Maksutov captured first prize for optical excellence at Stellafane, brought in a mirror grinding machine and let it run while he discussed optical fabrication. The renowned astronomy popularizer John Dobson made a surprise appearance and electrified the audience with his ideas about telescope making and the Universe. Comet expert Dan Green of the Smithsonian Astrophysical Observatory outlined many of the important contributions amateur astronomers can make to the science of astronomy, while Alan MacRobert, associate editor for Sky & Telescope, discussed some of the unconfirmed reports of astronomical anomalies that the magazine occasionally receives. The most exciting moment of the day came when it was announced that Michael Rudenko, who was sitting in the audience, had discovered his third comet only hours earlier. Rudenko, who lives in Amherst, MA, discovered his first comet in 1984 to become the first Massachusetts resident to discover a comet since 1862. Field trips included an observing session at Amherst College Observatory and a trip to the Springfield Science Museum for a look at the oldest existing American-made planetarium in the world.

Today the international event is co-sponsored by 13 Astronomy and Astronomy education organizations including: the Astronomical League; the Astronomical Society of the Pacific; the Royal Astronomical Society of Canada; the American Astronomical Society; the Astronomical Association of Northern California; the Planetary Society; the Western Amateur Astronomers; the American Association of Physics Teachers; the National Deep-sky Observers Society; the Association of Lunar and Planetary Observers; the American Meteor Society; the Association of Astronomy Educators; and the American Association of Variable Star Observers. The Astronomical League has published a handbook to help organizations host Astronomy Day events. The 120 Page hand-book is divided into three sections. The first section details the History of Astronomy Day along with detailed organizational ideas for hosting special events. In this same section are the dates for Astronomy Day for the rest of the century. Section two contains 50 pages of ideas for special events, including some display techniques, attention getting ideas, and activities that can be preformed on Astronomy Day. Two of the most important subsections here are "Light Pollution" and "Astronomy for Teachers". The latter has several sources for Astronomy Education materials including space camps, scholarships, teacher training courses and publications for classroom teachers. Throughout the handbook, dozens of names of companies and organizations are integrated into the appropriate sub-sections. Section three gives over 200 addresses for these organizations. Also included in the handbook are rules and entry forms for the Astronomy Day Award. This award is given annually to the group or organization that hosts the best events for Astronomy Day. Cost for the handbook is $7.00 in the United States, $8.00 outside the United States surface mail or $10.00 air mail. Postage is included. All payments should be in U.S. funds. All checks should be made payable to the Astronomical League. Organizations wishing free rules and entry forms for the Astronomy Day Award without ordering the entire handbook should send a self addressed, stamped legal size envelope to: Gary E.
