ASTRO: NGC 4449 Very fuzzy
I'm down to processing stuff that I started but got clouded out and
never got back to try again. In this case I tried this guy very low in the sky where seeing was very poor. I've had to do a lot of work to get much of anything out of it. Then the shots were all taken through high clouds that greatly reduced the light. While the lum image is 5 ten minute shots I doubt it has more total light than I'd get in 10 minutes of clear skies. This thin data made sharpening nearly impossible. LR routines were worthless. So I lost most of the HII regions I'd hoped to get. RGB data is even thinner with only one 10 minute frame for each. To get what I did I needed 4 nights all of which were lousy. But it was vanishing fast into the sun and tree line so I tried anyway. Since I'm posting everything that at least looks something like the object here it is. Don't laugh. There's always next year. NGC 4449 is a star burst galaxy with much the same size and features as the Large Magellanic Cloud. It's about the most similar galaxy I know of. It has HII regions all across it but under my lousy conditions I only caught a couple near the north end. At least it is bigger than NGC 6745 in my last post! 14" LX200R @ f/10, L=5x10' RGB 1x10 all 8 frames heavily obscured, STL-11000XM, Paramount ME. 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". |

Rick,
looks good to me. I also post everything I have processed, and this is certainly not a picture that I would have hesitated to post. Stefan "Rick Johnson" schrieb im Newsbeitrag ...
