Cleaning Optics

Posted By Robert Wilshusen

I have never cleaned any of my optics, but I have many eyepieces, a 4 inch objective, and an 8 inch SCT corrector that have dew spots.  The eyepieces also have a lot of eyelash oil. Also, an unknown fingerprint on the SCT corrector.  My question:  Can optics be safely cleaned using the pre-moistened lens wipes used to clean eyeglasses?  I use the Zeiss brand on my eyeglasses with no scratches or residue.

Thank you Rod for the Televue link.  Lots of concise information and instructions.  I will start with my low cost eyepieces first to get some practice, then progress to the good stuff.  Again, thank you Rod and Televue for the help.

Noob ready to buy first scope

Posted By Robert Wilshusen

Hey Dave, congrats on the new scope!  Large Open star clusters like the 7 sisters (M45) are spectacular in any telescope.  In the same region of the sky, check out my favorite, M35 with nearby NGC2158 in Gemini.  Others are M36, M37, and M38 in Auriga. They are all big, bright, easy to find, and spectacular!  Welcome to a lifetime of fun!
