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

: Housing the lenses in a tube, often reinforced with materials like fiberglass for durability, and painting the interior flat black to minimize internal reflections. making a refractor telescope norman remer pdf 12 new

Many builders avoid refractors because a standard doublet lens requires finishing , whereas a Newtonian reflector requires only one parabolic surface. However, Remer points out a major manufacturing advantage: a lens surface can be four times less accurate than a mirror surface to achieve the same optical performance.

Step-by-step instructions for designing, grinding, and polishing a doublet lens. : Provides a comprehensive summary of the book's

By following these steps and tips, you can create a functional and enjoyable refractor telescope, inspired by Norman Remer's classic design. Happy building!

Detailed methods for testing the lens's accuracy and making corrections. However, Remer points out a major manufacturing advantage:

: Study the index values for standard tool glass like BK7 (Crown) and F2 (Flint).

Bringing the surfaces to a reflective, smooth finish. 5. Testing (Figuring): Ensuring the curvature is precise. 6. Testing the Pair: Testing the crown and flint together. 7. Designing the Cell: Mounting the lenses.

Norman Remer wasn't a professional optician in a large optical lab; he was a coach for the amateur community. He wrote his book to demystify the process, acting as a step-by-step guide. He was part of a proud lineage that includes pioneers like Albert Ingalls, who first taught amateurs to make telescopes.
