ASTRO: Sh2-115 revised
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. Rick -- Correct domain name is arvig and it is net not com. Prefix is correct. Third character is a zero rather than a capital "Oh". |
