Given all the efforts, the result is somewhat disappointing. Processing was a real challenge, since light beams from the nearby star Phekda (γ Ursae Majoris) are spread all over the FOV. I ended up with an extremely flattend background and very little stretching. To be honest, right now this represents all of my processing skills (poor enough), but i just do not want to discard 12+ hours of integration time.

Version B:

Bad weather for weeks nails me down to post processing. This one was tough - still there is a lot of alien light in the background to eliminate, the little Mak is not very suitable for DS photograpy and so on. But with gained experience and skills i was able to do a little better. I used different stacks for background, stars and the galaxy.

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.
