M81 & 82- first Deep Sky with new camera

Last night was the first outing for the new to me ZWO ASI 533MC PRO. I started with a bit of lunar whilst getting a look at the settings and then married the camera up to my RVO Horizon 72ED and flattener for a bit of deep sky.

This was also the first time I had tried PHD2 guiding since finding and watching a tutorial that pointed me towards some errors I was making before.

I had to force PHD2 due to the area I was imaging.

I went for 20 x 120 second exposures but PHD2 stopped guiding after 8 as there was a problem that I need to diagnose at some stage (I can't for the life of me remember what the message was but it had something to do with pulses failing)

Therefore, this is the result of 8 x 120sec exposures. no flats, darks etc. Stacked in DSS, histogram stretched in SIRIL and levels adjusted in GIMP. not brilliant (far from it in fact) but, I am pleased that I can now do long exposures without trailing thanks to guiding.
