Have you looked thru a Baader solar film type ?, and with the glass is the resolution better than the film and what color is the image ?
Ive got a 11 inch schmidt and I was thinking of makin a filter.
Just wondering?

Hi Dave,
Its the thousand Oaks Glass full aperture filter which produces a nice amber color and not blue or white like the baader film.
The Baader film is susceptible to finger print degradation and pin holes
I have the 4inch filter that I place on the cap with the 4 inch aperture stop that came with my 6 inch refractor, the resolution is very good.
if your 11 inch Schmidt has a lens cap with an off center aperture mask, I would purchase the smaller filter for the aperture stop, You either purchase such a lens cap if you dont already have one, or just make your own.
