Making A Refractor Telescope Norman Remer Pdf 12 New Jun 2026

This article explores the core principles of Remer's refractor making process and highlights modern, 12-step refinements—or the "12 new" approaches—that can take your home-built refractor from good to exceptional. Why Build a Refractor?

Many amateur telescope makers (ATMs) start their journey into refractor building after mastering simpler mirrors. The direct experience of those in the community is invaluable:

Unlike a mirror which has one optical surface, a doublet lens has four surfaces (R1, R2, R3, and R4) that must all be ground to precise, calculated curves.

Building your own optical instruments is a deeply rewarding pursuit for amateur astronomers. For decades, DIY telescope makers have sought reliable, step-by-step documentation to guide their craft. One of the most sought-after resources in this community is Norman Remer’s foundational work on refractor design. making a refractor telescope norman remer pdf 12 new

Guidance on mounting the finished lens and constructing the telescope.

Building a refractor based on classic ATM principles involves several distinct phases: Phase 1: Sourcing Glass Blanks and Grits

: The original book often came with a CD-ROM containing Excel spreadsheet programs . These programs allow users to design a well-corrected lens without needing deep expertise in optical theory.

You rub the two glass blanks against each other (or against a tool) with coarse grit to hollow out the desired radius of curvature.

: Longer focal lengths are more forgiving of minor manufacturing errors in the lens curves. This article explores the core principles of Remer's

For many amateur astronomers, the idea of grinding a lens is often dismissed as an "insurmountable task" reserved for professionals. While thousands of hobbyists have successfully polished parabolic mirrors for Newtonian reflectors, the refractor—prized for its unobstructed, high-contrast images—is frequently overlooked in the DIY world. Norman Remer’s seminal work,
