The rule of thumb for cleaning telescope mirrors is - DON'T. Unless the mirror is extremely dusty, it doesn't need cleaning. All the dust will do is offend your sensibility. The image will not change by cleaning. Brent --- Joe Bauman <bau@desnews.com> wrote:
Hi, I'm hoping one of our list folks can give me some information as soon as convenient. I'm planning to head out for some astrophotography soon, and as I was working on some problems (like making a hyperfocal lens), I had the telescope set up during the daytime. This gave me a good look at the corrector plate and it was fairly dusty. The last time I cleaned a corrector plate was with my old Celestron 8" and I really screwed things up -- I took the corrector off and failed to note its alignment, so I got it back on wrong. I was never again able to collimate it well. Now with my new 12" I don't want to make mistakes and I won't be taking the corrector off.
What I would like someone to tell me -- particularly an experienced old hand like Patrick, Chuck, Siegfried, Bruce, etc., etc. -- is a good, safe, quick way to clean the dust from the surface of the corrector. Any suggestions? Or does anyone have any stories to share on this?
Thanks very much, Joe
