The Crescent Nebula is an emission nebula in the constellation Cygnus, about 5000 light-years away from Earth. It was discovered by William Herschel in 1792. (Wikipedia)
Magnitude: 7.4Distance to Earth: 5,000 light yearsConstellation: Cygnus[/left][left]Equipment used: Celestron Evo 8" SCT on AVX mount with ZWO 294MC Pro main cam and ZWO 120mini guidecam, 60mm guidescope, ASI Air Plus, Optolong L enhance filter, ZWO EAF, Bathinov mask, dew heater straps and powered by two Jackery units. Last night, epic data acquisition for 4 hours, yielded 4 full targets worth of data, 20 x 180sec light subs for Crescent nebula. Pre and Post processing done in Pixinsight, with touch-ups in Paintshop pro for clarity and vibrancy. Two versions, original stars deemphasized and Stars-less, enjoy!

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.
