Amateur astronomers have a choice between instruments that are commercially available or becoming amateur telescope makers and building ones that are more suited to their needs. For the latter, the amateur has the freedom of instrument design as well as selection of specific components that represent the best available instead of compromising with what is provided with a commercially built unit.
