Dear DSF,
I was wondering if anyone has seen the tidal streamers of NGC 4651, the "Umbrella" galaxy.
A look at the POSS II image seems to suggest that it might be just within the reach of Jimi's 48", and probably well within the reach of professional telescopes that some in the forum have access to:

Of comparable brightness on POSS II Blue plates are the bridge in Keenan's system. The shells of NGC 474 seem brighter, as is the tail of the Tadpole galaxy.
A look at this R. J. GaBany image explains the name "Umbrella":
