Chuck, I LOVE the solar telescopes you made for Chris, they are amazing!!! (You made those right?) I used a Borofloat glass (1mm thick). The same glass we use at our color filter manufacturing business for the lighting industry. A comparison between my design and one without glass would be something I want to see.

Excellent, John!
You should know that wrinkles do not affect the performance of Baader material- that aspect is covered in the instructions. The wrinkle discussion has been held here before.
I worry more about resolution loss because of the 4 additional optical surfaces involved. Are the glass layers 1/4-wave optical glass?
It would be interesting to compare high-magnification views of your installation vs. the recommended installation.
Thanks for posting!

Here is my new Solar Filter. I placed baader solar film between 2 pieces of glass and bonded them together. Created a filter holder and siliconed it all together. I was concerned about the amount of wrinkles that formed in the film inside the glass but it does not appear to affect the view. Thanks to Seth at the Clark Planetarium for selling me the baader film!!! You are the man! http://img36.imageshack.us/img36/6378/su2s.jpg [1] http://imageshack.us/photo/my-images/543/telescopewithsolarfilte.jpg/ [2] _______________________________________________ Utah-Astronomy mailing list http://mailman.xmission.com/cgi-bin/mailman/listinfo/utah-astronomy [3] Send messages to the list to Utah-Astronomy@mailman.xmission.com [4] The Utah-Astronomy mailing list is not affiliated with any astronomy club.
