The tripod is often not seriously considered by photographers in general, but is an extremely important bit of photographic kit, and absolutely necessary here if sharp results are required. There are many types available, and cost can vary dramatically depending on features, and durability. For the purpose we are considering here, a relatively light unit will do, as long as it is capable of holding the camera and lens combination without movement. If a tripod is being acquired for general use, the best unit which provides both portability AND stability is the aim. The camera should be capable of being easily attached and removed, whilst not being in danger of falling off, or overbalancing the unit.
