Question on content for Celestron
Where did the above information come from? Celestron is a company that makes telescopes, particularly schmidt-cassegrains. Perhaps this Celestron was something sold in other countries? I've just never heard of this telescope design and would be interested in seeing some documentation.
I moved User:172.158.63.83's question above from the article space Maksutov paragraph to Talk here, and it's a good question; it sounds a lot like the Questar [1] (http://www.questar-corp.com/acc.htm) as that was a Maksutov but I cannot get detailed specs of how the finder and main mirror were integrated. However Celestron also make a Maksutov design with a flip mirror, so I'm not sure. -Wikibob | Talk 12:10, 2004 May 20 (UTC)
I looked up Questar telescopes and found on Company 7's page a description [2] (http://www.company7.com/library/questar/quedist.jan56.html) that matches. I also looked up the Questar site [3] (http://www.questar-corp.com/questar.htm). On Celestron's site I found [4] (http://www.celestron.com/prod_pgs/tel/nx4gt.htm). Basically, the paragraph in question could probably be clarified.... Elizabeth (User:172.158.63.83)
I modified the Maksukov reference to Questar... the flip mirror (it was really a sliding prism)/"viewfinder" is covered in Questar's early 1950's patent, and was (and still is) a hallmark of the scope. At $1000 (1957) then and today's $4000 (for a 90mm diameter scope), it has forever been in the "luxury" class. ... Dick (User:128.95.100.19)
how does a spherical mirror have less magnification than a parabolic mirror of the same focal length? Rsduhamel 03:21, 31 Dec 2004 (UTC)
- it doesn't. Duk 08:53, 31 Dec 2004 (UTC)
Oops, my mistake. Must have had too many tabs open. I meant to post this question on the talk page for Schmidt corrector plate. Anyway, Duk, you know that, and I know that but the page on the Schmidt corrector said different. I have made the correction. Rsduhamel 06:40, 1 Jan 2005 (UTC)
