NGC 4631/ NGC 4656 (1, 2)  Neyer 5.5″ TEC APO refractor (f7.2) STL11000M  49.5  Baader,  LRGB  Antares Observatory, Switzerland Feb 2013 – Mar 2014 This image contains a possible tidal tail behind NGC 4656 that could have been produced during an interacting process with NGC 4631.

 

The situation of nebulae around NGC 4631 was described by Taylor & Wang (2003). They show a dust arc in the northern part of the galaxy. Comparing image #3 with the TBG image of Fabian Neyer (image #1 and #2) we clearly see that deepest optical images may be used for confirmation of radio (CO) structures.
