Reflecting telescope principle and model please?

Click For Summary

Discussion Overview

The discussion revolves around resources and principles related to building a reflecting telescope. Participants explore the feasibility of amateur telescope making, the necessary components, and the complexity involved in the process.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant requests resources for building a reflecting telescope and understanding its principles.
  • Another participant suggests checking Wikipedia for basic principles and notes the complexity of building a telescope from scratch, emphasizing the need for a thorough understanding of how they work.
  • It is mentioned that modern manufacturing methods have made commercial production of finished mirrors more economical than building them from scratch.
  • A participant references Newport Glass Works as a source for ATM kits that include finished mirrors and other necessary components, highlighting the extensive work involved in the project.
  • There is a suggestion that while building a telescope can be a significant undertaking, it may allow for the creation of higher quality optics than those commercially available.

Areas of Agreement / Disagreement

Participants express differing views on the popularity and practicality of amateur telescope making, with some suggesting it is less common now due to advancements in commercial production, while others highlight the potential benefits of DIY projects.

Contextual Notes

Participants note that the complexity of building a telescope can vary significantly based on design details, mirror size, and desired quality, indicating that assumptions about skill level and resources may differ among individuals.

can anyone please give me any resource for building a reflecting telescope (and also the underlying principles)
(sorry if it's not the right place to ask)

Completely the wrong sub-forum to post this question in, but for basic principles you can check http://en.wikipedia.org/wiki/Reflecting_telescope. If you actually want to build one from scratch, you have a lot of work ahead of you, starting with fully understanding how they work. I don't know if anyone grinds their own mirrors anymore, so you'd probably start with a finished mirror and build from there, which can be fairly simple or extremely complicated depending on design details, how big the mirror is, and how good a telescope you want to wind up with. Pick up a subscription to Sky and Telescope, you'll learn a lot and get an idea of what you're getting into thinking about building one.

Amateur telescope making [ATM] is not quite as popular as it was 20-30 years ago. Modern manufacturing methods enable commercial production of finished mirrors cheaper than they can be built from scratch. Newport Glass Works http://www.newportglass.com/ngwkitp.htm sells very nice ATM kits at reasonable prices, and typically include a finished secondary mirror [making an optical flat is usually more difficult than making the main mirror]. The price includes aluminizing the primary once complete. Of course you will still need a tube, mirror cell, spider, focuser and mount. All in all, it is a great deal of work for very modest [if any] cost savings. It is, however, possible to build higher quality optics than commercially available. It is a good project for a hard core DIY'r with plenty of time to spare.
