The Amateur’s Guide to Building Refractors: Insights from Norman Remer

Making a refractor telescope is often seen as a daunting task compared to building reflectors, but Norman Remer’s seminal book,

, proves otherwise. If you've ever wanted to tackle the "superior image forming capability" of an unobstructed refractor, this guide is your essential roadmap. Why Choose the Remer Method?

Most amateur telescope makers (ATMs) stick to parabolic mirrors because lens making is perceived as insurmountable. Remer acts as a "coach," guiding readers through every step using common tools similar to those used in mirror making.

Spherical Simplicity: Unlike complex parabolic mirrors, all surfaces in a doublet lens are spherical, making them easier to manage with the right patience.

Design Tools: The book originally included a CD-ROM with Excel spreadsheets to help design lenses corrected for color, coma, and spherical aberration.

Ready-to-Use Plans: For those who want to skip the math, Chapter 12 provides seven specific "prescriptions" for doublet lenses ranging from 3 to 8 inches in aperture. Key Stages of Lens Fabrication

According to Remer’s step-by-step approach, the process is broken down into clear, manageable phases:

Material Selection: Understanding glass characteristics, abrasives, and pitch.

Grinding: Shaping the lens surfaces. A crucial tip for beginners is to practice on "scrap glass" or cheap glass blocks before moving to expensive optical glass.

Polishing & Testing: Bringing the surfaces to a high-quality finish and using specific tests to check for errors.

Correction: Fine-tuning the lens to ensure optimal image quality.

Mounting: Final assembly into a telescope tube, ensuring proper alignment of the doublet elements. Where to Find the Book

Since its publication in 2006 by Willmann-Bell, this book has become a staple for DIY astronomers.

Retailers: You can find new or used copies at stores like Agena Astro, First Light Optics, and Amazon.

Secondary Markets: Reliable used options are often available from AbeBooks or Biblio.com. This write-up outlines the process for designing and

Making a Refractor Telescope: The Definitive Guide for Amateurs

Building a high-quality refractor telescope has long been considered an advanced feat reserved for master opticians. However, Norman Remer’s seminal book, "Making a Refractor Telescope: How to Design, Grind, Polish, Test, Correct and Mount a Doublet Lens," demystifies this complex craft for the amateur enthusiast. The Core Philosophy of Norman Remer

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.

A key insight Remer provides is that a lens surface needs to be only one-fourth as accurate as a mirror surface to achieve comparable optical quality, making the process more accessible than many assume. Technical Components and Design

For those starting out, the book focuses on the achromatic doublet, which consists of two glass elements designed to correct for optical issues like color (chromatic aberration), coma, and spherical aberration.

Materials: Builders typically work with glass types like BK7 and KZFS1. The process involves using specific abrasives, pitch for polishing, and testing methods to ensure the curves are correct.

Design Tools: 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.

Aperture Prescriptions: For builders who prefer not to design from scratch, Remer provides detailed prescriptions for lenses ranging from 3 to 8 inches in aperture. The Construction Process

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

Grinding and Polishing: Shaping the two elements of the doublet lens to exact spherical specifications.

Testing and Correction: Using optical tests to identify and fix errors in the lens figure.

The Optical Tube Assembly (OTA): Housing the lenses in a tube, often reinforced with materials like fiberglass for durability, and painting the interior flat black to minimize internal reflections.

Mounting: Attaching the finished lens into a cell and mounting the entire assembly on a stable base, such as an Altazimuth (AZ) mount for simple left-right and up-down movement. Availability: Finding the Book and Resources

Norman Remer's book was originally published by Willmann-Bell in 2006. While it has periodically gone out of print, copies can still be found through various channels:

New and Used Copies: Specialized retailers like Agena Astro and First Light Optics have historically carried it.

Marketplaces: Used copies are often listed on AbeBooks or Amazon.

Digital Access: Community forums such as Cloudy Nights are excellent places to find advice from other builders who have used the book and may share resources or design spreadsheets.

Demystifying the Lens: Making a Refractor Telescope with Norman Remer

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,

, aims to change that narrative. First published in 2006 by Willmann-Bell, this 391-page guide serves as a comprehensive "coach" for anyone looking to build an achromatic doublet from scratch. Breaking the Mirror-Making Monopoly

The common perception is that lens making is infinitely more complex than mirror making. Remer addresses this directly by explaining that making a lens involves the same common tools and simple practices used for mirrors. While it’s true that a doublet lens requires finishing four surfaces instead of one, all four are spherical, which can be easier to master than the parabolization required for high-quality mirrors. Key Features of Remer’s Guide

Step-by-Step Instruction: The book covers everything from selecting glass and abrasives to the final mounting of the lens.

Design Tools: It includes specialized Excel spreadsheet programs on a CD-ROM to help builders design lenses corrected for color, coma, and spherical aberration.

Ready-to-Use Prescriptions: For those who prefer not to design their own, Remer provides specific prescriptions for lenses ranging from 3 to 8 inches in aperture.

The "Why" and the "How": Remer explains the physics behind the craft, such as why a mirror surface must be figured four times as accurately as a lens surface to achieve the same optical quality. Why Choose a Refractor?

Despite the extra surfaces, the refractor offers significant advantages:

Superior Contrast: Without a secondary mirror obstructing the light path, refractors provide sharper views of planets and double stars.

Durability: Lenses are sealed in a tube, protecting them from dust and reducing the need for frequent cleaning compared to open-tube reflectors.

Maintenance: Once aligned and mounted correctly, refractors typically hold their collimation far better than other telescope types.

Whether you are a seasoned telescope maker or a curious newcomer, Norman Remer’s book provides the roadmap needed to move beyond mirrors and master the art of the lens.
