I have been imaging tonight with my GP-DX, Canon 60Da and Televue NP-101. I have SGP set to restart capture if the guide software PHD2 reports an error greater than 0.3 pixels. Every once in a while the GP-DX suffers a glitch enough to trigger that abort. SGP apparently immediately tries to restart the capture. Most of the time this works out fine, but occasionally it aborts/restarts several times almost continuously. After 5 aborts (and this number is consistent) the camera seems to lock up and the only way I can recover is to power cycle the camera. I’m thinking if there were a way to introduce a slight delay between each retry/abort the lock up could be avoided.
