to make it short...

The evening was to optimize guiding with PHD2 together with my new mount and working with APT's platesolving and dithering functions. After finishing my trial and error process, it worked well, but there was only left enough battery power for 18 frames, 180 seconds each.
Poor thing was, that APT somehow changed my lightplan from ISO800 to ISO1600. So I had to redo flat and dark frames.
