  • Focal ratio: Faster (f/6–f/8) reduces tube length but worsens chromatic and spherical aberrations for an achromat; slower (f/12–f/15) reduces aberrations but increases length and mounting difficulty.
  • Apochromatic vs achromatic: Apo yields superior color correction and edge performance but cost/weight scale rapidly at 12".

  • Philosophical approach: Remer spends as much time discussing patience, optical theory, and the satisfaction of grinding your own objective lens as he does on tools.

    Telescopes have fascinated humans for centuries, allowing us to study the night sky and unravel its secrets. While commercial telescopes are widely available, building your own refractor telescope can be a rewarding and educational experience. In this guide, we'll walk you through the process of creating a refractor telescope, inspired by Norman Remer's design. Building a Refractor Telescope: A DIY Guide

    • Aperture: 90 mm; Focal length: 1000 mm (f/11.1)
    • Sturdy mount, fine focuser, optional field flattener for imaging.

    The book demystifies the perceived difficulty of lens making by demonstrating that it uses many of the same tools and techniques as mirror grinding. Key topics covered include: Focal ratio: Faster (f/6–f/8) reduces tube length but
