Unusual interacting galaxies in Delphinus

About this image

While "wandering" through Delphinus (on my SMP star chart) i came upon a pair of faint galaxies in a rich field. The time was coming up to 2am and so I would finish with a few images. In Aladin the pair is part of a complex group with streams of stars. The following evening i took a much longer sequence of 68 x 1min subs. I cant find much info on this group.

Its not in the ARP's or imaged by Hubble nor any catalogues i have. Magnitudes are B14.8 and B15.7 at Redshift 0.028 (Aladin)
It should look superb at larger scale.

Camera settings: SharpCap(pro) gain=100, TEC -15C, offset 200, 8 dark frames. (Processed in DSS and AstroArt)
