Greetings All,
Here is an image of DWB111 otherwise known as the Propeller Nebula. I framed the object in an orientation that made sense for the object so North is to the right in this image. A full size image as well as exposure and processing details are at:

Very Nice. Sure looks like a propeller.

That's the perfect field of view and framing for this one, Jim.
DWB111 gets lost in the surrounding 'stuff' in widefield shots.
The color looks right on, too.

Nice one Jim. This one is aptly named, I think!

Good catch. Once again, great use of those focal reducers to get just the right framing.

Thanks for the comments folks. I appreciate the comments on the framing. It was chosen a little wider than the earlier image on purpose. I think it was a good choice.
