Nice capture Andy, you collected plenty of data and your tracking looks good. Not sure why you use so many different ISO settings, if I can and if I need to, I keep the same ISO setting and alter my exposure time , I think this helps with the dark frame's calibration unless you are creating different dark frames to match the ISO setting and exposure. I haven't ventured to guiding yet but for the first time this week I managed 2 mins unguided at 1000mm focal length, so I was happy with that. By the look of the stars at the edges of the frame in your shot, like me, we both need to buy ourselves a coma corrector! Keep up the good work Andy, you're heading in the right direction, well done.
