I’m watching my two systems trying to recover from a cloud front. In one case, the guidestar was lost and in the other, it was trying to do an AF routine, when cloud struck.
In the first case - even though it was a guidestar that triggered recovery, SGP does not look for the error condition to go away before recovery - it proceeds through a sequence of center and focus and then tries the guider - repeat. Another approach would be to look for the condition that caused the issue to go away before attempting a restart?
In the second, it is trying to autofocus a blank canvas. I think it is on its 4th iteration and has just now lost the guidestar too. I am not certain where the focuser ended up. There may be an opportunity to do something more with the AF failure - no stars were detected, but it carried on regardless.
In both cases, if PHD2 exposes a star intensity (SNR or star mass), there might be something that could be done to simply monitor until conditions reach a satisfactory level before attempting to restart?
