Joe, I have an Orion Sky Quest 8" GoTo. Every baader filter I have seen does not have glass, but I didn't want to puncture the film on accident so I bonded it. I would say it is not necessary at all. On 02.06.2012 17:18, Joe Bauman wrote:
Nice, John. What's your telescope? Rodger and I just made a Baader filter holder for my 12" -- actually Rodger did the work while I supplied the material and stood there with my mouth hanging open, watching him do it. Do you think the glass is absolutely necessary? Thanks, Joe

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!
