UGC 12073 (PGC 69101 and others) is the barred spiral at the center of this image. The galaxy is located approximately (https://iopscience.iop.org/article/10.3847/0004-6256/152/2/50/pdf) 225 million light-years away in Lacerta.

 

UGC 12075 (PGC 69110 and others) is the odd, Arp-like spiral to the left (east) of UGC 12073.

 

MCG+06-49-034 (PGC 69117 and others) is the even odder galaxy left of UGC 12075.

 

Luminance – 27x600s – 270 minutes – binned 1x1

RGB – 12x300s – 60 minutes each – binned 2x2
