The ATM's Workshop

Tips, Techniques, and Projects for the Amateur Telescope Maker / Astronomy Enthusiast

Welcome To The ATM's Workshop Website

Amateur Telescope Makers (ATMs or TNs [Telescope Nuts] for short) are a varied lot. Our workshops often reflect that diversity. In our quest for that perfect telescope or accessory, we resort to building some or all of the components ourselves. ATMing can span the gamut from building everything yourself to just making modifications or accessories for your favorite manufacturer's product. ATMing as a hobby allows you to bring your own unique ideas, skills, and talents from other hobbies to the forefront. In this way, you can enjoy the pleasure of working at a combination of several of your hobbies at the same time.

The ATM's telescope and equipment often says a lot about the builder's other hobbies. Many ATM's telescopes are works of art in terms of woodworking, metalworking, optical or mechanical design innovations, electronic accessories, or some other aspect. While many ATMs build their own telescopes to save money, others do it for the fun, satisfaction, educational value, and varied other reasons. In addition to building telescopes, ATMs often end up building many of the specialized tools their hobby projects require. This can often lead to new projects that build (and feed) upon themselves and can lead the ATM into worlds they never knew existed.

Website Feature Article Contents

This website contains a number of quite long articles dealing with various aspects of amateur telescope making and astronomy in general. Each of these articles strives to cover the topic at hand to the same depth you might expect from a detailed magazine article or chapter in a book. To amateurs who have already built a complete telescope or ground, polished, and figured their own telescope mirror, these articles may seem ponderously slow reading. For those new to the hobby, I hope the detailed coverage of each subject will serve as a step by step starting point to understand the processes and methods at hand.

The feature length articles here are organized into sections to make the subject information easier to find. Some articles don't fit well into just one section so are indexed in multiple places. Hopefully, you will be able to find just the information you need without having to browse or read the entire website.


Construction notes, reviews, usage notes, and modifications you can use to get the most out of your telescope equipment.


Projects, techniques and tips you may use while making your own telescope optics.


Observing methods and accessories to make observing more ejoyable.


Home machine shop projects and tips for making a more polished looking telescope.


Woodworking projects and tips for making some of the tools used by ATMs as well as a more beautiful finished telescope.


Tips and techniques to get the most out of your interest in astrophotography.


Electronics projects, circuits, and tips for enhancing your telescope or making the pursuit of astronomy easier and more ejoyable.


Software, program snippets, and techniques associated with astronomy, telescopes, and telescope making.

Potential Future Articles

This area lists potential future feature articles which I woud like to write as time and energy permits.

Website Blog Entries

A number of short articles are included on this website as blog entries. These entries are often little more than musings on subjects related to astronomy, amateur telescope making, and other DIY activities. They are being consolidated here from several other sources. The blog articles are indexed both by topic (to make them easier to browse) as well as by date. The two indices are cross-linked so that the reader can explore more easily.

About The Author

John D. Upton is a retired electrical engineer living in central Texas, USA. His formal educational background is in science and engineering holding Bachelors degrees in both Physics and Electrical Engineering. He has been interested in and pursued astronomy as a hobby for over 60 years.

His interest in amateur telescope making began in the mid 1960s after reading Neale Howard's book Standard Handbook For Telescope Making. It was several years before he ground and polished his first mirror -- a 6" F/8 that was actually quite bad. That experience was followed with several 8" and larger mirrors which turned out to be quite acceptable performers.

While he currently observes and does astrophotography with commercial telescopes and mounts, his interest in and love for ATMing is alive and well. More often than not in recent years, the DIY aspects of his hobby have been embodied in tools and accessories to make astronomy more enjoyable and rewarding.
