Congrats on the new toy Chris. It's a good start, nice colour coming through and the resolution is great. You can see some finer details starting to come through. Another couple of hours worth of data should really bring them out. One thing to maybe check is your stack settings. There seems to be a couple of stacking artefacts caused by hot and cold pixels that have remained in your final image. No biggie and it can be easily removed by adding some Bias calibration frames. If you're already doing this then you might just need to tweak the settings in the Bias/Offset tab. Apart from that you're heading in the right direction. Well done!
