So the latest release of APT v4.60 is available - and it adds something I suggested a while back - that I am finding a real boon! Using PHD traking data and HFR analysis of each frame Ivo and Maria added two new meta data tags one can add to image file names - Sky Quality and Image quality - and I love them!
At a glance one can seperate great images from so so one immediately!
Everything else works brilliant - I am finding automated merdian flip and recentre target (within 10 pixels) is really handy!
