RE: [APML] Cassiopeia through Cygnus region 28mm H-a
Brian, consider stopping down a stop to get some of that vignette out. I
know it doubles the exposure, but it may be worth a try once.

Heres my last image using the 28mm for H-a work.
I think either the lens is showing artifact due to the
H-a, or the film isnt lying flat.
Im pretty sure this is the lens artifact issue.
At leaste m31 made it in there<g>.
Heres the not so perfect shot:
