Description

Taken with my C9.25 + Baader OD5 solar film filter, a standard red filter, and an IMX533 camera.
Not a great raw image but hopefully I'll get better; the C9.25 + Baader film is more of a visual platform really.
But I'd like to keep trying.

I think a UV/IR cut filter would help "trim the excess" from the R filter - the spots weren't that dark.
I had to play with contrast in GIMP to give them depth.

Something like the Baader 35nm Ha might be better than a basic R filter, but I don't have one.
