Making A Refractor Telescope Norman Remer Pdf [updated] -

Purists will argue, but Remer himself was an innovator. He would approve.

Yes, but be careful: ED lenses have different spacing requirements. Use Remer’s mechanical design but recalculate baffles using a ray-tracing program like OSLO or even the free Rayica for Mathematica. making a refractor telescope norman remer pdf

For many amateurs, the goal is not just observing—it’s the satisfaction of pointing a telescope at Saturn that you built with your own hands. Remer’s book captures that spirit perfectly. Purists will argue, but Remer himself was an innovator

Once ground to shape, you polish using on a lap that matches the desired curve. Polishing brings transparency. Figuring – the art of correcting the spherical surface to a parabola (or, for an achromat, to a specific sphere that minimizes color error) – is done with local retouching. Once ground to shape, you polish using on

Before Remer published his definitive book, information on building refractors was scattered across obscure journals, outdated patents, and cryptic forum posts. Most ATM literature focused on the Newtonian reflector because it involves grinding only one curved surface and requires only flat mirrors for the secondary. A refractor, however, requires grinding and polishing two separate lenses (a crown and a flint), each with two precisely curved surfaces, and then cementing or spacing them perfectly to correct for chromatic aberration.

Fundamentals of achromatic doublet lenses, including how to select glass types and manage focal ratios.

In an age of mass-produced, disposable telescopes, building a Norman Remer refractor is an act of resistance—a statement that you value craftsmanship, understanding, and the quiet satisfaction of a well-made instrument.
