Abell 2666 is located about 340 million light years away in Pegasus.  Its largest member is the huge cD elliptical NGC 7768. The distance would seem to place this within the Perseus-Pisces supercluster, but Atlas of the Universe suggests that the galaxy groups in Pegasus form an independent small supercluster.  I haven't seen any discussion about this elsewhere one way or the other.

My favorite galaxy in this group is the heavily distorted barred spiral PGC72600 in upper left, which is almost a ring galaxy, with a "fan" of stars spreading to its upper right.

 

Full details of capture and processing are below the image.

I really like seeing galaxy clusters (and always want to see the final image at the image scale at capture ;-) ) . You captured a lot in only 8.25 hours.

Thanks, Dan and Hans.  Hans, I could show it at 0.6" but it would be ugly.  :)  My imaging setup gives me that scale, but I've never found it useful to display galaxies at less than 0.9", although once in a while I display small planetary nebulae at 0.6".  More time on target might have let me display at a smaller scale.  I'm shooting the NGC 1060 group now, and I hope to get 20 hours total.  We'll see if that helps.

  Intriguing image that I would like to take a shot at.  Really unusual and a delight to the eyes.

Thanks Peter, Gunny and Anil.  BTW, I completely forgot to mention that I have an annotated image here:
