M51 effort from Cambroon

Had hoped to catch a few low northern Messier objects from Ron's (Astroron) open night at Cambroon. Lots of frustrating problems getting going, so missed almost an hour of imaging while M51 was a bit higher. Astroplanner says I shouldn't have been able to see this at 19:45, so Ron's NW horizon is better than I thought. Only about 5-10 degrees high at the time with slight haze. Fairly heavily processed to pull back red and noise, but I'm stoked to have something to show for the night.

I had quite a bit of trouble getting guiding to behave at all and had to turn EQMOD pulse guiding settings way above normal - is this normal at extreme north DECs anyone, or more trying on alignment/mount performance?

4 x 5mins ISO 800, fully calibrated
450D + MPCC on 8"

(many thanks again Ron!!)
