Instruments25x30 "spyglass" telescope w/Welco gold shade 14 welder's filter - Charlie
I took the scope apart last night and found that there is a lens or lens pair at the bottom of each tube segment. I can't get to all of the glass surfaces because some of them are deeply recessed, but I blew on everything I could and wiped the exterior surfaces and there are a lot fewer spots on the sun today than there were yesterday. Thre are still more thre than there should be.

Disclaimer
This is my personal record of my astronomical observations. It was written for my personal reference. The only reason it is in a blog is that a blog is a very convenient way to get the records formatted more or less uniformly and they will, hopefully, have greater longevity at Google where the servers are backed up than on my hard drive which never gets backed up. I occasionally include copyrighted material in my posts. I do this to make it convenient for me to access things I think I might want to refer to again. I think of this like making a photocopy of something I read that I put in a file where I can find it when I want it. As I understand copyright law, as explained in the DVD series Copyright Compliance by Chip Taylor Communications, this use is allowed under the Fair Use doctrine since I am not making any money on this blog, I don’t publicize the blog, and only occasionally post small excerpts of copyrighted works.
