Making A Refractor Telescope Norman Remer Pdf 12 New [new] -

Building an f/12 refractor using Norman Remer's principles is a rewarding challenge. The result is an instrument that often outperforms mass-produced telescopes, offering the "sharp as a tack" stars that only a well-made refractor can provide.

For decades, the amateur telescope making (ATM) community focused heavily on building Newtonian reflectors. Parabolic mirrors were considered the only viable project for a backyard builder, while refractors were dismissed as too complex.

Norman Remer's Making a Refractor Telescope is a beacon for those who wish to explore the rewarding, if challenging, path of building their own refractor. For many, the journey begins right here: in the pages of a book and the simple, powerful decision to begin.

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:

A telescope is only as good as its focuser. For a high-f-ratio refractor, a 2-inch Crayford or Rack-and-Pinion focuser is recommended. Ensure the drawtube is long enough to reach focus with various eyepieces but doesn't vignette the light path. Finding the PDF and Resources

Guidance on mounting the finished lens and constructing the telescope. Building an f/12 refractor using Norman Remer's principles

Ensuring the lens elements are properly mounted, spaced, and aligned.

If you’ve built a refractor from Remer’s book, post your photos below. I’m currently grinding a 4″ f/12 and the Ronchi test section alone was worth the search.

After the glass is close to its final shape, the polishing stage begins.

: It naturally minimizes chromatic aberration compared to "faster" (shorter) telescopes.

: Remember that managing four surfaces takes roughly four times the processing time of a standard Newtonian mirror—but the resulting contrast is unparalleled.

Using silicon carbide abrasives to hog out the glass and establish the required radii of curvature.

Norman Remer's book, Making a Refractor Telescope , is widely considered the definitive guide for amateur astronomers interested in building their own doublet lens instruments. First published in 2006 by Willmann-Bell, the book demystifies the perceived difficulty of lens making by demonstrating that it uses the same tools and practices as mirror making.
