Data: mag 11.6  size 3.5' x 2.0'
Position: RA :  DEC :
Description:
This is supposed to be one of the colliding galaxies.
Nowhere to be seen at 22x or 30x.  Caught a glimpse with my new 12mm Radian at 
73x, the Galaxy Grabber, looking like a dim patch at the edge of detection.  
It’s elongated and seemed to be pointing to a group of stars that forms a 
pyramid shape: SAO 171460, SAO 171464, GSC 5945:2084, SAO 171475, SAO 171475.  
At 110x, the galaxy is definitely a dim patch, especially with averted vision, 
elongated and seem to be pointing at the star GSC 5946:1784 instead the 
pyramid.  Overall, extremely dim at the edge of detection.  I couldn’t detect 
any “collision” of the galaxies.   Later, after some research, I realized why I 
couldn’t see IC 2163 (see photo via link); it was probably part of the NGC 2207 
blob through the Light Cup.
