Description

>>>>>>> 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!
