Good shots, Allan
I'm particularly impressed with your shot of NGC5090 and its companions. You know, if you look carefully, you can see many more galaxies in that shot. I counted at least another 6 that I could positively identify and I will bet that many of the the faint dots in your shot are galaxies too. Some, of course will be dim stars. Looks like you've pushed that shot to about 17mag, by the looks of those really faint dots. You want to try and up the exposure and see if you can bring out those faint fuzzies
It'll be better at a darker site, anyway. Go for a drive upto the Glasshouse Mts and try from there.
