I did 10x10min in the morning before sunrise after shooting the pleiades at the same FL. This was with the QHY8 at prime focus on the GSO8" F/4 Newtonian.
Few technical issues with it. I originally planned at home before packing the MPCC spacing with the OAG in between and everything was setup just to find out on the first night that I couldn't rack the focuser in enough to reach focus. So the following day I re-arrange it as best as I could with the bits I had in hand but the spacing was all wrong. Still sort of ok on axis and some nice resolution.
Big one
here. Thanks for looking.
