New Image: Sh2-155 The Cave Nebula in HOO
I just think the time could have been better spent on a different target, that's all. I did work all day today and process this rather quickly when I got home. Maybe fresh eyes on it tomorrow will change my mind. But I'm not sure I'll be gathering any more data on this subject from my backyard. I think this is truly one that requires a dark site for the OIII data.

Re: New Image: Sh2-155 The Cave Nebula in HOO
I imaged this target a couple of years ago and wished that I hadn't spent the time to image it. I blame everything on my skies, so I just chalked it up to poor skies.
I spent 9.5 hours on it and finally on the eighth re-process, I had something that I could live with (barely).
Maybe leave it alone for now and come back to it later. You really do have some fine data there.
Your processed image is quite nice. The details are fantastic!

the colors and details are very good.
I also understand that 62 hours is a very long time, I can't wait to see the reprocess. thx Greg.

I came up with something I like a little better but still am not happy with. I think it's time to move on to something else...
