Making A Refractor Telescope Norman Remer Pdf 12 New

: Understanding glass characteristics, abrasives, and pitch.

Remer's book is a masterclass, but it's honest about the challenges. Its provided prescriptions stop at 8 inches. Why? A 12-inch refractor is an enormous leap in complexity and cost.

Because different wavelengths (colors) of light bend at different angles when passing through glass, a single lens will create distracting color halos around bright objects like the Moon and planets. To fix this, Norman Remer's book focuses on creating an —a two-element objective lens system: making a refractor telescope norman remer pdf 12 new

A forward, biconvex lens made from low-dispersion glass (such as N-BK7) that converges the incoming light.

Before diving into fabrication, it helps to understand why an amateur would take on the challenge of a lens rather than a mirror. : Understanding glass characteristics, abrasives, and pitch

Optical schematics and interference patterns require close inspection. Digital PDFs allow builders to zoom in closely on line drawings and mathematical formulas without losing resolution.

A refractor is only as good as the mount that holds it. Due to their long focal lengths (often f/15 or f/16), large refractors require sturdy, vibration-damping mounts. Amateur designs include:
