Propeller Nebula Simeis 57 (DWB 111)

Simeis 57, also known as the Propeller Nebula, is a captivating celestial object located in the constellation Cygnus.

It is part of the vast Cygnus X molecular cloud, situated approximately 4,600 light-years away from our Solar System.
This intriguing nebula resembles a spinning propeller, with opposing arcs of reddish light extending symmetrically from a common center.
Its unusual appearance has earned it nicknames like the Garden Sprinkler Nebula.
While challenging to observe visually due to its red emissions, astrophotographers have captured its beauty through long integration times.

With an impressive integration time of 96 hours at f3.3, the propeller shape within the nebula appears more diffuse compared to the surrounding regions. However, this extended deep capture reveals new intricate details around this renowned celestial feature.

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.
