The Propeller Nebula is an emission nebula and is part of the Cygnus X molecular cloud complex, an area rich in HII. It lies approximately 4600 light years away, roughly in the center of the Deneb, Sadr, & Delta-Cyg stellar triad. It was originally catalogued in the 1950s by astronomers working at the Simeiz Observatory in the Ukraine as the 57th out of 306 objects they cataloged in the HII region. The DWB catalogue was created in the 1980s by Dickel, Wendker, & Bieritz who cataloged the HII region of the Cygnus X complex. DWB111 refers to the southern arm while DWB119 is the designation for the northern arm.

The final HOO /bi-color image was created using the narrowband normalization process for OSC cameras developed by Bill Blanshan which can be downloaded & installed as a process in PI.

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.
