That's a good result Chris. It seems to be a more difficult target than it should be. I had my third go this morning. Got up extra early, made sure mount, refractor and guidescope were all perfectly aligned. But SGP decided it wasnt going to show me the "frame and focus" window. No idea why. So had to abandon and do manual shots at the camera. Second problem was that part way through the shots the camera switched from RAW to JPG. Again, no idea how or why - never encountered that before. But worst of all I left my Bahtinov mask on the telescope ! I even managed to get PHD tracking the comet head perfectly. I got some nice star spikes I guess
