In 2017, I subscribed to one of Deep Sky West's (https://www.deepskywest.com/) programs, which provided data from a 135mm Rokinan lens attached to a QSI 583 WSG5 camera. This HaLRGB image is a from a reprocessing of that data. The system was located in New Mexico. The data consisted of 11.8 hours of LRGB subframes plus 3.2 hours of Ha. It was processed using Pixinsight and, to a lesser degree, Photoshop. The Ha was added to the linear RGB image before color calibration (SPCC) using the Crazed Conceptions method (https://www.youtube.com/watch?v=LwuiS8N1A-E). GraXpert AI was used to remove gradients. Color calibration utilized SPCC.

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.
