LBN 251 The Longhorn Nebula. Another of the many less common gems hanging around in Cygnus. It amazes me how much good stuff there is in this constellation but the masses only seem to be interested in 6-7 super common objects.

All of this data was gathered starting at an 80% waxing moon and continued through the full moon. In fact, I did the oxygen signal during the full moon. Don't let anyone tell you things aren't possible during full moon. Yes it has a noticeable impact on the data but with a bright enough object, sufficient distance from the moon, good filters, and decent processing, you can still make good use of full moon periods.

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.
