gonna make solar filters

I learned from Jim Kendrick that he sells full sheets of Baader solar film. So that means I can make custom filters for our telescopes and my binoculars.

Prices in Canadian funny money.

250mm X 250mm $33
250mm X 500mm $54
330mm X 500mm $65
1000mm X 500mm $116

And I learned from Geoff Gaherty on the Talking Telescopes Yahoo! group that it is best if I make a full aperture filter as opposed to a small off-axis filter. One will see much more detail.
