Last night, I somehow managed to tease out and sketch this very faint interacting galaxy pair N 5257/58, (VV 55, Arp 240) in Virgo. Using my 10" Dob at 170x and all the AV I could muster I could, from time to time, see this facinating pair. Both showed as extemely faint knots, like spots beside each other. I certainly did not have any hopes of seeing any faint tidal connection between them. They may show better in my 12.5" Dob next time.
