Well, I had a bit of a go tonight, with mixed success. All obs with 4.5" f8 reflector and 21mm EP (47x). I didn't bother with Hickson 62 or NGC 2573, no chance in my scope, or the Homonculus, which I've never been able to see. Had a shot at ESO 92-18 and even with the exact position visible per detailed chart there was nothing there.
So on to the good news! Didn't know what to expect from NGC 3109 as these large LSB dwarf galaxies can be very difficult in a little scope. Was pleasantly surprised to see it quite clearly as a very dim, dull glow, long and narrow with a visible length of 12-15 arcminutes in averted vision. It was just beside two close stars.
I could make out pn NGC 2438 in M46 as a very small, round dull glow in averted vision, nestling in the side of this great cluster!
NGC 5170 I had misgivings about at mag 12.1, and just using a cross marked on an old Astronomy 2006 yearbook chart I lucked out, plonking the scope smack dead centre on the field! Right in the middle of the view was an extremely faint edge-on galaxy, perhaps 5-6 arcminutes length in averted vision. I took a note of the star patterns around it and ventured back to the computer to confirm it. By the time I got outside again there was some light cloud moving through, and despite getting my night vision back the transparency had noticeably gone off. I was unable to see NGC 5170 again.
Then I just did a quick run through the others - the Leo Triplet wasn't that flash, reflecting the poorer transparency, and while all three galaxies were visible, NGC 3628 was very faint. NGC 5128 was fair, and in averted vision I could see the dark lane going right through the galaxy. Nice cruising around the Coal Sack, surprising amount of stars there and not as black as it seems, LOL!
Cheers -
