The autumn sky abounds with little bundles of galaxies scattered throughout its stars. One of the best known is the group of 7 galaxies that surround the magnificent spiral NGC 7331 in Pegasus, the Flying Horse. An observer could easily spend an hour or more just soaking in all that this small patch of sky has to offer.

The NGC 7331 group is certainly a good target but unfortunately it has the DSO nickname that I find the silliest, even more so than some of the doozies in Hidden Treasures, since it was named after an observing site in North Carolina.

Agreed, Dave.  But I don't name 'em, I just write about 'em. :lol:

The Deer Lick Group, along with nearby Stephan's Quintet, are objects that I go back to again and again--and spend a lot of time at the eyepiece each time.  From my experience, you should save these objects for the darkest, most transparent nights, and use the highest magnification that conditions allow. 

 

A complicating factor with the "fleas" is the wide range of magnitudes listed for these objects in various sources.

 

I have seen 3 of the "fleas" with my 8-inch SCT at 182x--and suspected the fourth (NGC 7336)--but of course will wander back there on the next excellent night...
