Default ASTRO: Sh2-115 revised

You may be right. I see the world in low contrast right now. Hard to
judge. After surgery I will see what I think. Right now it looked way
too flat until I punched up the contrast. Might be the eyes however.

Very good picture Rick, maybe I would have preferred a bit less contrast.
I'll have to find out where this patch of sky is...
I hope all goes well in hospital. I guess it is an advantage that you are a
CCD photographer and not a visual guy.

I'm due for cataract surgery soon, find out Wednesday when. Anyway I
don't see fine detail well any more. Should after they get both eyes
fixed but that's a month apart. Anyway I didn't see that my H alpha
darks didn't work well. I didn't have any. Apparently when I took this
I expected to take them but never did. I used some 10 minute ones that
were current and scaled them but that's a far bigger scale than I've
ever had work. I was pleased to see it did. Except I've been told
(many times now) it didn't. I blew it up so my eyes could see the
damage and it was severe. I went back and found some 15 month old darks
that didn't need scaling. I figured they'd not work but they did
surprisingly well. So here's the full size image with a better set of
darks applied to the H alpha data.
