To Chrismo,
You can make a filter very inexpensively this way. I made one for my 10" by sandwiching the baader film between two rings cut out of black foam-core board and then making a ring around the outside using two layers of black poster board. I finished off the edge with black vinyl electrical tape and it looks great, works great and cost me less than $30. I think that the view from this is as good as a glass filter.
Thanks Rodger Fry

Just curious, since I don't know much about this end of things... would this film be "as good" as more expensive glass filters? I was planning to buy a filter for my 8" scope, but it looks like this stuff would end up costing about $100 less. Also, how would you go about making a filter using this material? would you just make a frame to fit over the end of the scope?

How much do you need? I have a big sheet of Baader visual film, but am making a couple filters this week. I might have enough for a small scope left over.
There are a couple ISS solar transits in Northern Utah coming up in the next week or so.
