NGC7380 and little bubble

Since the weather has not been cooperating I've been revisiting some data from this time last year. I've changed cameras since then but I learned some different processing techniques so I thought I'd try them out on old data. My recent post of IC410 was one of these experiments.

Well, this is NGC7380 in Cepheus. It has many interesting "wave-like" dark nebulae which make it look like part of a restless ocean. One of the interesting objects within NGC7380 is another bubble nebula. It is much less well known but it would be a great target for those of you (Dan Kowall) with big RC's or other larger aperture/longer f.l. instruments. My humble AP 155EDF can pick it up but not with much detail.

The first post is of NGC7380. The image on the next post is cropped to show the bubble.

Sweet shot Thomas!
I was not aware of a "Little Bubble"... thanks for sharing! 8)

It was already on my list, Tom. What a long list it's getting to be, too. That's all right, I wouldn't want to run out of things to image.
I think you did a wonderful job on this area. I looked at your version from last year. The bubble was not real obvious in that version, but this latest version has a nice bluish cast to the bubble. I believe this is the 'truer' color representation, too.
I have read that this is thought to be caused by a Wolf-Rayet star.
Jim Thommes has a fine version of this area, too:
