Had a play with the info icon in the sequencer which now gives you info if anything goes wrong.
Set up a simple sequence using M45 with V2 cam simulator and EQMOD ASCOM Simulator for the mount and a very short sequence of 5 x 10s exposures.
All fires up fine and the initial Dither happens and it settles for the 10 seconds I have set. As each exposure begins the Info box receives the following message:
“Failure while integrating M45; Event 1: Frame *** of 10S. Image has not downloaded in allotted time period”
Every time an exposure ‘BEGINS’, I get one of these messages and each exposure is successfully downloaded anyway.
