Making A Refractor Telescope Norman Remer Pdf 12 New

For builders who want to skip complex optical math, . These blueprints outline specific configurations for building doublet lenses using standard, reliable glass blanks—typically combining a crown glass element (like Schott N-BK7 ) and a flint glass element (like SF1 or F2 ).

Then came Norman Remer's book. It directly challenged this notion, arguing that making a lens involves the same simple practices and common tools as making a mirror.

These classic stock designs span across several apertures and focal lengths:

Throughout the guide, Remer offers a range of tips and techniques to help individuals build a high-quality refractor telescope. Some of these tips include: making a refractor telescope norman remer pdf 12 new

| Book | Best for | Difficulty | |------|----------|------------| | Remer – Making a Refractor | Refractors only | Advanced | | Texereau – How to Make a Telescope | Newtonians + refractors | Intermediate | | Berry – Build Your Own Telescope | Newtonians | Beginner |

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.

While the physical book is a collector's item since the closure of Willmann-Bell (though now managed by the American Astronomical Society), many hobbyists look for digital versions for easy reference in the workshop. For builders who want to skip complex optical math,

To fix this, Remer explains how to use two different types of glass mated together:

Using digital cameras and software to analyze Ronchi fringe patterns, allowing for precise figuring rather than relying solely on visual interpretation.

Detailed guides on using the Foucault test, Ronchi test, and star testing to check the precision of your lenses. It directly challenged this notion, arguing that making
