Taken from DeepSkyWest, this is my first image of the new year.

Obviously one of the most photographed nebulas in space, I felt I had never really done this object justice. My previous attempts were from Bortle 6 zones, and with OSC.

I think this came out pretty great, although I had some issues with blowing out stars during stretching. I was especially frustrated when doing ArcSinh stretch resulting in the edge of stars having weird red optical aberrations. I ended up doing an arcsinh stretch, and blending that stretch in with the stars from a less aggressive stretch to try and recover some of the star color and detail while still getting the benefits of ArcSinh.

I am pretty pleased with the results thus far! Would love constructive feedback or criticism!

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.
