Here is an image of Sharpless 261, a.k.a. LBN 864, a.k.a. Lower's Nebula. I wish I could have done a bit better with the framing.

You have some wonderful, subtle color shading, Jim.
That small, blue, translucent fan-shaped structure just left of center looks interesting.

Nice catch of yet another object I've not heard of before, Jim!

Thanks all for the comments.

Dan,
I am pleased you noticed that blue fan shaped area. It was interesting. I was not sure if it was caused by a reflection in my blue data (being right next to the bright blue star). I concluded due to its shape that perhaps there is some reality to it. In any event, it was in the data and not an obvious artifact to my eyes so I processed it as is.

Outstanding shot, capturing some interesting detail. The feature toward the center with a string of stars is intriguing and completely absent from your earlier shot. I was amazed at that one in and of itself that it was shot with a web cam. I am surprised on that one that you didn't get alot of noise on the long Ha shots or did you modify it for cooling and such.
