InstrumentsBrunton 8x21 compact binocular w/Welco welder’s glass - Charlie
I knew I would be compromising my ability to see spots by using the small binocular, but I wanted to see if I could see the spot I saw yesterday with 2x the magnification and image stabilization. I should have had the Canons along to compare the view in real time, but was going to be in a public space and didn’t want to have to carry a lot of stuff around or to worry about security of my equipment.

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.
