Astronomical Dawn stopped my sequence

#1

Post by Beepa »

Was running sequence about 8:30 PM (laptop, CPWI all time synced) and sequence stopped because of command: (Stop running these steps when astronomical dawn occurs (or has occurred). My time was about 16 hours past last astronomical dawn (admittedly the same day) but was still 8 hours from next dawn. Is that expected? Does it only pertain to before or after on the same calendar day?? Thanks, Beepa

Hi,

I think that is correct behaviour - the step is 'Stop running when astronomical event happens or has already happened'. This meanst that any time of the day after the sun has come up will be considered a time to stop running the contained steps.

The goal is to have some predictability - maybe you have some imaging of the brightening sky inside that step and then after it finishes you want steps to run that park the mount and close a dome (or similar).

If the stop only happened at the instant of astronomical dawn then you would have a situation where if dawn is at 07:30 and the 'stop at dawn' step starts at 07:29 then it would stop after 1 minute. However if it started a bit late (07:31 say) for some reason then it would run for 24 hours until the next dawn!

cheers,

Robin
