Simeis 57 - Propeller Nebula

Revision title: Complete Reprocess

I actually didn't know this was a named target. I was just panning around using a site based on Aladin, looking for my next project. I sent the framing to my friend and said "look at this interesting bit of nebula in Cygnus", and he promptly informed me that "yeah, that's the Propeller". I guess I need to get out (and look up) more!

Anyway, this was a really fun project. All three channels were relatively strong, with the O3 being the weakest, but not weak. The O3 was pretty difuse and fills much of the frame, blocking most of the pure background. That can sometimes make background extraction difficult, and some best guesses must be made at to what is truly background sky. I went for a little softer approach than I have with other targets. To me it seems almost like a "soap opera" filter effect. In this case I thought it worked, and calls attention to the neat little dust lane in the foreground.

The part that resembles a propeller is actually made up of two different catalogued objects, DWB 111 and DWB 119. The entire Propeller is designated as a single target Simeis 57.

C&C are always welcome.

Description: This was a complete reprocess. I really like this target, but have not really been able to get the data where I want it. I think this is an improvement though.

Description: I was never really happy with the first few attempts at processing this. I went at it fresh with some new techniques and tools.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
