Remer’s work serves as a "coach" for amateur telescope makers (ATMs), guiding them through the transition from making mirrors (for reflectors) to crafting doublet lenses. He argues that making a lens utilizes the same fundamental tools and practices as mirror making—namely grinding and polishing spherical surfaces.

Building a refractor involves several meticulous steps that go beyond the glass itself:

: Housing the lenses in a tube, often reinforced with materials like fiberglass for durability, and painting the interior flat black to minimize internal reflections.
