Excellent target, Uwe. I observed it in July (20", 360x, SQM 21.83, 4800 ft, good seeing):

NGC 5753 small, roundish.


In 5755, nonstellar nucleus on E end of extended core. Massive arm loops from E end of core N then almost to E end of core. Short arm opposite, points toward stars E.


5752 comparatively small, extended generally NW-SE and concentrated to the center. It is slightly integral sign-shaped with ends pointing E and W.


The core or bar of 5754 is oriented similarly to -52. It is enclosed in a ring with outer arms emanating CCW from near the ends of the bar. NE arm loops back and is enhanced in P.A. 30. SW arm has a similar enhancement opposite and extends around E [should be W] side of the galaxy inward of -52. Outermost arm or tidal tail on S side of the pair is visible as a diffuse arc, unconnected to either member, and much thicker than in the original photograph.

P.S. Regrettably I did not check for the tail W of -52, but since the N half of the outermost arm of -54 was invisible, so too would probably be the W tail.
