❌ No longer in print – physical copies are rare and expensive ($100–200 used).
❌ Outdated supplier list – many surplus lens sources are gone.
❌ No digital edition – so any PDF is a bootleg scan (often poor quality).
❌ Assumes advanced machining skills – not for the casual hobbyist.
❌ Heavy focus on 60–100mm objectives – larger sizes get less detail.

Once you find the PDF, here is why it’s considered an interesting essay rather than just a manual:

  • Contrast to reflectors: Most ATM books focus on mirrors (Newtonians). Remer argues that making a small refractor (3-4 inches) is actually more educational and yields a more durable, sharper planet scope.

    • | 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 |

    It is highly likely that the "12" in your search term is a typo or an auto-complete error. In the telescope-making community, Norman Remer is most famous for a different specific mirror size.

    That said, here is a review of the book itself based on the actual content and reputation among amateur telescope makers (ATMs).

    ✅ Only dedicated refractor-building book of its era – fills a huge gap.
    ✅ Extremely detailed machining drawings – if you have a lathe, you can follow them.
    ✅ Covers lens testing (Ronchi, Foucault) as applied to refractors.
    ✅ No fluff – dense, technical, and practical.
    ✅ Timeless techniques – still relevant today.

    Making a Refractor Telescope is considered the definitive modern guide for amateurs who want to grind, polish, and figure their own lens (objective) rather than buying one.
