The pair of galaxies really fooled me for a moment in thinking that it was a real double, a wide pair of faint stars.

I was on my way to NGC5371, using the 40mm Pentax for low power/wide field, when I noticed the two faint dots close to some striking fieldstars. Moving on to NGC5371, almost in the same FOV, I made a mental note of the pair.

After having observed NGC5371 I checked Skymap to see if more (observable) galaxies were around and found, of course, NGC5353, NGC5354 and the also nearby NGC5350.
NGC5353 and NGC5354 are galaxies with a smal, bright core's. That makes them look like stars at first sight, especially with low power, but a good look reveals then as small fuzzies. 5353 is the brightest of them and because of its starlike appearance it is the best visible of all 4 galaxies.

The distance between the centers of 5353 and 5354 is only 1.3' ! 
NGC5350, about 4' away from this close pair is larger, round and more diffuse. No bright center is visible, only a slight brightening of the central region.

These three galaxies are set in a field of some bright stars which makes them easy to locate. The stars also mark the way to NGC5371, 27' to the east. This galaxy is also large, diffuse and has an oval shape. It shows a bright starlike core, that much starlike that I'm thinking of a foreground star. You can have a look at this picture:

The galaxies 5350, 5353 and 5354 can be seen on this wonderful image:

I didn't notice the elongated shape of 5353. I think it's worth another go with careful examining of these galaxies.

What a nice group for last place on the list. Four distinctly different types, three of which are in close proximity. Only problem for visual observers is the bright 6th mag star in the same field. NGC 5371, the outlier, is a large spiral, one of those in the many books. However, those arms are very faint 14-15th mag at best. They just showed up in the image of 50 video frames stacked.
