For over a century, the amateur telescope-making (ATM) community has thrived. Since the publication of Albert Ingall’s first volume of Amateur Telescope Making , amateurs have crafted thousands of telescopes using surprisingly simple tools. However, the vast majority of these instruments are reflectors—telescopes that use a parabolic mirror to gather and focus light.

For decades, the amateur telescope making (ATM) community focused heavily on building Newtonian reflectors. Parabolic mirrors were considered the only viable project for a backyard builder, while refractors were dismissed as too complex.
