IC 4592, The Blue Horsehead Reflection Nebula

I ventured out to the dark site with Astrobin buddies elmiko and Ray Hienle last night. Conditions were good for imaging and I took advantage of covering the section of sky obscured from my backyard. This target ended up being challenging as the individual subs were so dim that my less than desirable framing was not evident until everything was stacked. Afterwards, processing was a challenge as I'm still trying to master reflection nebula processing. I suspect I'll keep going back to this one to see if I can improve it. It would have benefitted from more luminance data but the session ended earlier than desired when the target dropped to low and guiding was no longer feasible.

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.
