First attempt at Cleaning SCT Corrector
Posted 21 May 2004 - 09:39 AM
Scope is now dust free from brushing......
I use sterile cotton balls and Kleenex, unscented, white tissues and starting at the inner part of corrector working out to the edge, I wet a cotton ball and gentle swipe.
Cotton sticks and fuzzes the corrector. So I wet a Kleenex and try again. Kleenex removes fuzz, but when it dries, leaves Kleenex dust all over scope.
And so this goes on for about a half hour....wiping, drying, and dusting.
When I finished it looked better than before I started, but it still have a couple of little, tiny spots on it. Also may have a streak or two.....I won't know for sure until I take it outside in bright daylight.
All I can say is......What a major pain in the _ _ _ !
I will NEVER take my scope outside EVER again without a dewshield!!
Speaking of dewshields....my Kendrick dewshield showed up yesterday! Wow! It is really nice!
The Baadar Solar Filter looks Awesome as well! Can't wait to get my scope outside this weekend and check it out!
On another note.... I am having my scope collimated tonight by Laser Collimation at the St. Louis Astronomy Association Meeting. This should be interesting and hopefully I'll start seeing crisper views with my scope! Well, I should, unless I have streaks on my corrector from my attempted cleaning! :bangbangbang:

I don't think the streaks will be much of a problem, plus in one sense they will be clean streaks.
I also doubt they'll effect the performance. I've been observing a few times with great views and spotted the corrector lens was covered in a film of dew - it's quite amazing how much you can still see through a thin film of dew!
I always use my dew shield because it helps prevent stray light entering the tube as well and serves two purposes for the price of one solution.

PS. Also make sure that no one ever uses that make-up brush for anything else or you'll have a REAL mess next time!!

I had a 8" SCT and never noticed this huge handprint on the inside of the corrector until one night I looked at it with a flashlight.

Tim- I made sure that I put the make-up brush in my scope case for future use....
TopCat - Good point about the breath and Kleenex. I'm going to try that tonight after work. That's all I did to clean my eyepieces was to breathe on them and wipe them with a super soft optical cloth. They turned out better than the scope! :rolling:

I think you'll find that method put a nice polish to it. I've done that a number of times to clean my ancient c80 refractor with no problems to date.

Hmmm... not sure how safe that cleaner would be on a scope with XLT coatings.
It sounds like you will be cleaning the mirror (XLT coatings)... ??
