Markarian's Chain C9.25

I had hoped to do a 2-panel mosaic of Markarian's Chain this spring, but unfortunately between forest fire induced evacuations, torrential winds, clouds and terrible seeing conditions I was only able to capture 11:52 in subs on the first half of my intended project over ~two months. This would be the right hand panel of the mosaic, ideally with approximately twice as much time on just this side.

As I mentioned, seeing conditions were generally unfavorable leading to less sharp detail than I know my equipment is capable of gathering, even on the "good" nights.

Hopefully I can get some more data on this panel next year, and another ~20 hours on the other side and finish the project.

Sometimes projects in this hobby progress on "astronomical" timelines...

Description: Not sure why I sometimes get slightly darker centers in brighter stars, but I did this time and I fixed it in this iteration.

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.
