Propeller Nebula Ha widefield

The Propeller Nebula is located in the very large Cygnus X nebular complex. The distance to the Propeller Nebula is somewhat unclear, but estimates to the Cygnus X complex is documented as approximately 4,600 light years. It mostly emits at the line of hydrogen-alpha, while it is much dimmer on other wavelengths. The stars or other sources responsible for the ionisation of the gas is also still to be identified. The mass of the cloud is less than 50 Solar masses, according to estimations.

The Propeller nebula is commonly referred to, somewhat incorrectly, as DWB 111. Actually DWB 111 is one of the propeller's blade, whether another blade is designated as DWB 119. Whole complex designated as Simeis 57.

The entire frame depicts also faint stuff nebulosity around Propeller.

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.
