Sharpless 119 is just to the left of the North American Nebula. It is a region that also includes a number of Lynd's Bright Nebula objects - the most notable of which is LBN 400. I ended up doing a two frame mosaic since my chip is so small. Even at that I didn't get it all. Image can be seen here:

Very nice...your H-alpha time 9 x 6 minutes for each frame of the mosaic?

Tom, Richard, Jason, Thanks for your comments.

Richard, best wishes for your efforts should you decide to return to the area. I saw your earlier even wider field of the area. It would be interesting to see you do some close ups.

Beautiful image Jim!

Jim,

What can I say - very nice. I would love to know how you color manage during processing. Your images always have such wonderful, deep color. I seem to be doing something wrong still with my RGB data and can't get that great color, especially in the stars.

cheers,

Jeff
