Building a refractor telescope following Remer's guidelines requires patience, specialized testing tools, and a methodical workflow: making a refractor telescope norman remer pdf 12 new
Most amateur astronomers build reflecting telescopes because finishing a single parabolic glass surface feels achievable. However, reflecting systems suffer from a central obstruction—the secondary mirror—which scatters incoming light and degrades image contrast.
You rub the two glass blanks against each other (or against a tool) with coarse grit to hollow out the desired radius of curvature.
Building a refractor telescope can be a fun and rewarding project. With careful planning and execution, you can create a functional and enjoyable telescope for stargazing. Norman Remer's design serves as a great starting point, and with these instructions, you can create your own refractor telescope.
A polished lens is not yet a telescope. It must be tested and corrected to ensure it focuses light properly. A positive lens made of low-dispersion glass (e
Using Teflon or modern plastic spacers, designed with computer modeling, to prevent lens edge stress (edge astigmatism).
By combining Norman Remer’s structured, methodical engineering insights with modern testing shortcuts, any patient astronomy enthusiast can craft an instrument capable of delivering breathtaking, razor-sharp views of the planets and the moon.
While Remer designed lens cells out of machined aluminum or cast bronze, modern builders use 3D printing (using rigid filaments like PETG or Carbon Fiber PLA) to prototype lens cells and baffling systems rapidly.
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. : The hardbound edition typically includes a CD-ROM
Clear skies and happy building.
by Norman Remer is widely considered the definitive modern guide for amateur telescope makers (ATMs) seeking to build high-performance doublet lenses. Originally published by Willmann-Bell, Inc. , this 408-page textbook demystifies a branch of optical fabrication that was long thought to be too complex for the backyard workshop. While the amateur astronomy community has historically focused on grinding parabolic mirrors for Newtonian reflectors, Remer outlines how common tools and patient, structured practices can yield highly superior, unobstructed refractor optics.
by is an essential guide for amateur astronomers who want to move beyond mirror-based telescopes. Published in 2006 by Willmann-Bell, Inc. , this 391-page hardcover book serves as a "coach" for making high-quality doublet lenses. Core Content & Scope
