DWB 111/119 - The Propeller Nebula

The Propeller Nebula, also catalogued as Simeis 57 is an emission nebula that is part of the Cygnus X complex The southern "arm" is catalogued as DWB111 while the northern arm is DWB119. This whole area is very rich in HII regions and has a strong response with an Ha filter. The Cynus X complex lies around 4600 light years from Earth. On the upper left corner there is a very interesting small planetary nebula. Had I known it was there I would have framed this differently or done a mosaic. Its designation is PM1-320 and there are few amateur images of it. It was discovered in the 1980s. Unfortunately it falls in the very corner of my image, where the stars are worse (I have a spacer to add to my imaging train, according to NINA my backfocus is still a bit off).

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.
