The Hunter Rising - 26 Panel Mosaic

This is a 26-panel mosaic of the Orion constellation, or at least most of it. It could have been done in 20 panels, but I'm not very good at aligning panels and had to go back and shoot some more to fill in gaps. Shot with my modded Canon 600D, iEXOS-100, and Rokinon 135mm f/2 at f/2.4. I used 2-minute subs for each panel, plus a handful of 20-second subs for the Orion nebula, but didn't really use them as it made the composition look weird without the nebula being much brighter than the surrounding dust. Subs were guided in PHD2, dithered every three frames. Bortle 3 skies.

The panels were shot from January through March of 2021, individually integrated in Astro Pixel Processor, and then assembled into the mosaic in APP. I had to group it into sections and then combine the sections, and then reduced the overall file size to 0.75X as I ran out of RAM to work on the entire FOV. Stars reduced in Starnet++, and recombined with final adjustments in GIMP.

As always, C&C welcome and appreciated!

V2 will be a JPG with a much smaller file size...

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.
