Last night was my first try with autofocussing, it seems to be a lot better than I have been able to manage so far. There were other tweaks, I changed the separation between the reducer and the camera and added an Ha filter.
I do feel this is my best effort so far (but that isn't claiming a great deal!)
The Sharpstar 15028 is incredibly fast, this was one evening's data. I feel I overexposed the L frames at 20 seconds. I was too inconsistent with the RGB times and I have a lot to learn about guiding. This is the result of running the frames through APP on the preset values and then tinkering in Photoshop. I always just want to see what I have got. I will now have a more leisurely go with PI.
