Would a frame grab from the BTA-6 in-dome webcam qualify as fair use? There's no copyright information on the webcam page. I would imagine {{web-screenshot}} would be the most appropriate.--BillC 11:13, 28 August 2005 (UTC)
[edit] 'Largest telescope in the world?'

Re: Zelenchukskaya, I thought that all mirrors larger than the BTA-6 were segmented, or have some solid mirrors a greater diameter? --BillC 12:31, 9 April 2006 (UTC)
- After reading List of largest optical reflecting telescopes, I stand corrected. --BillC 13:00, 9 April 2006 (UTC)
The BTA-6 is the last big mirror of old "stiff" approach, and ever since mirrors have been placed on dynamic actively controlled supports, and thinner larger diameter glass plates are feasible for actual telescopes. -- Oh2mqk 9 Apr 2006
- Now that sounds more like it. If we have a reference for this, it should be in the article. --BillC 07:38, 10 April 2006 (UTC)
