Making A Refractor Telescope Norman Remer Pdf 12 New Direct

. While amateurs have crafted thousands of reflecting telescopes using mirrors, many have long viewed lens-making as an insurmountable task due to the perceived complexity of grinding multiple surfaces. Remer’s work demystifies this process, proving that making a high-quality doublet lens involves the same fundamental tools and techniques used in mirror-making. Amazon.com Overview of the Book The book spans approximately 391 to 408 pages

Norman Remer shattered this myth with his definitive book, . Published by Willmann-Bell, this text serves as a comprehensive roadmap for constructing a high-quality doublet objective lens from scratch.

While Remer’s techniques are fundamentally sound, modern advancements in materials, testing, and coatings allow for significant improvements. Here are 12 modern refinements ("12 new" techniques) often discussed in modern ATM circles:

For a DIY refractor, an f/12 to f/15 ratio is ideal. Long focal lengths significantly reduce chromatic aberration (the "purple fringe" around bright objects). making a refractor telescope norman remer pdf 12 new

You will not find a legitimate, free PDF of Norman Remer's Making a Refractor Telescope online. The book, while out of print, is a copyrighted work from a reputable publisher. The copies you might find on file-sharing sites are illegal and often unreliable. My mission here is not to point you toward a pirated copy but to show you how to legally and effectively use Remer's work to achieve your goal.

: 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.

Typically low dispersion, placed at the front. Amazon

If you want to learn how to make a from scratch (or from affordable parts), I will write you a comprehensive, original 2,000+ word guide based on verified amateur telescope making techniques. I’ll cover:

Keeping lenses aligned to within thousandths of an inch.

Using simple Fizeau interferometers to map the surface error of the lens, providing a numerical PV (Peak-to-Valley) or RMS value of the lens quality. Here are 12 modern refinements ("12 new" techniques)

For those seeking guidance on a 12-inch refractor, the book serves as a critical conceptual and theoretical foundation. While its direct prescriptions stop at 8 inches, the design and figuring principles it explains are fully applicable to larger apertures. To pursue a 12-inch project, you would need to pair the knowledge from Remer's book with advanced optical design software or collaborate with an experienced optician, as the book itself does not include a turn-key prescription for this size.

Implementing advanced computer-modeled baffle systems to minimize stray light, often overlooked in older designs.
