NGC3079, Double Quasar and a lot of other galaxies

>>>>>>> The image above is a crop, please click here to see the full field! <<<<<<<<

Version A:

30 x 600s Luminance. Unfortunately collimation was a bit off. I guess this field contains more galaxies than foreground stars!

On the plate solve, the Double Quasar is marked as PGC2518326, a bit more than a NGC3079-length above NGC3079. (and a bit more to the right) near the star KR-Uma.

Other names for this object: Twin QSO, SBS 0957+561, TXS 0957+561, Q0957+561 or QSO 0957+561 A/B

Colour version will be next.

Version B:

First I made a new stack, also using some extra data form a few days earlier. Total is 6 hours Luminance now.

Version C:

In the final image I added 6 x 600s each RGB of mediocre quality, but I am pleasantly surprised by the result! Total 9 hours exposure time.

Version D:

Crop, the Double Quasar is not visible in this image!

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.
