If your going to actually wipe the lens at least use one of the cloths made for wiping camera lenses. They are going to be the nicest to your lens Bob Moore Commerce CRG - Salt Lake City office 175 East 400 South, Suite 700 Salt Lake City, Utah 84111 Direct: 801-303-5418 Main: 801-322-2000 Fax: 801-322-2040 BMoore@commercecrg.com www.commercecrg.com -----Original Message----- From: utah-astronomy-bounces+bmoore=commercecrg.com@mailman.xmission.com [mailto:utah-astronomy-bounces+bmoore=commercecrg.com@mailman.xmission.c om] On Behalf Of diveboss@xmission.com Sent: Monday, May 07, 2007 1:27 PM To: utah-astronomy@mailman.xmission.com Subject: Re: [Utah-astronomy] dirty lens You should probably use some of that compressed air they sell at camera stores to gently blow the dust off first. The finish of the corrector plate is critical to the overall view through your scope. With rifle scopes, we use compressed air first, and then move to a liquid cleaner to "float" the remaining debris away from the lense. I would think that is what you would need to do to your 12" Meade. Quoting Joe Bauman <bau@desnews.com>:
My outermost lens is pretty dusty on my SCT 12". (Sorry, I can't remember what it's called -- is it a corrector plate?) Would it harm my telescope to gently dust it off with a specialty cloth used for computer screens? Any suggestions? Many thanks, Joe
