ASTRO: SH2-110 in S2HaO3 @ ~ 10 hours
I am not as happy with this as I was hoping I would be at this time. I
probably have about 10 hours exposure binned 2x2 at f/12.6 one issue is that I haven't had proper darks and have had to get by. It makes the image a bit noisier. another is that I have a peculiar reflection in my [OIII] flat/filter in this scope that I have not seen in my 400mm camera lens I suspect that there's something reflecting some light somewhere and is better at reflecting green than red I also have a bit of a problem with reflections in my main baffle tube. I believe those are responsible for the large offset haloes around the bright stars. I changed how that was flocked during the spring and now I can see that to get the results I want I need to further refine that. all excuses aside here it is. at this scale it looks better than at full rez :-) |

Interesting. 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". |
