Deerlick Group and Stephan's Quintet

I think I let this one get the better of me and I almost gave up halfway through it. This image was also affected by collimation problems I initially couldn't figure out. Both a spider screw and a focuser screw came loose due to the seasonal temperature changes. If it were one or the other, I think I would have solved it faster, but I spent about 4 clear nights wondering why I was collimated around Polaris, but completely off at the zenith. I ultimately finished only because I had a number of clear nights in a row (from 9/24 on, minus 2 nights) and didn't have a subject picked out that was up as soon as it got dark. I'm glad I finished it, but this one didn't come out as well as I was hoping. It's better than last year's attempt, but I think I need a higher focal length scope to really make this one work the way I want. I'm hoping to get an 8" RC and Astrophysics 0.67x reducer some time next year. I think it'd frame this one nicely.

I simplified the acquisition details a bit, because I spent too many nights capturing different datasets. I had to trash a lot, but data that made it into this was captured on 9/09, 9/11, 9/13, 9/24, 9/25, 9/26, 9/28, 9/29, 10/01 and 10/02.

I have never had so many subs affected by planes - I should upload a stack of just 'plane' subs - I probably have at least 25.

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.
