Well, unfortunately the mystery continues. Three nights ago all went well and I made progress in upgrading my knowledge; I collected three image sets via plate solve pointing.
Then two nights back SGP again crashed during the focus routine. Its a major crash. It says 'downloading image' but this takes forever. I know that if I click 'abort' the whole program will crash. Finally, after 60 secs I click 'abort'. The whole program crashes and refuses to work for the rest of the night.
What I forgot to do here was to switch laptops; I have two in the observatory (one collecting all-sky-camera data) and this works for SGP crashes..... Problem is I still don't know why SGP crashes violently when it loses camera connection. The same camera still collects normally to any other program.
