This started as a quick detour last night while waiting for the Horsehead Nebula to clear a rooftop: 4 hours of 5 min exposures. It came out surprisingly well, although I'm still trying to sort out come apparent chromatic aberration issues on brighter stars.

On January 7th, I added 3 more hours of 10 minute exposures to experiment with AstroPixelProcessor and varied exposure lengths. I think it cleaned up very nicely, and there's a bit less CA since I fixed a slight tilt in my image train.

Title: 48 x 5 min (sessions 1-2) + 18 x 10 min (session 3)

Description: Here, I add 3 hours of 10-minute exposures to see if we could bring some more details out. The blue reflection nebula has a bit more detail, but otherwise I think we've arrived at a result (at least for this year!)

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.
