Why do you set Filter Delay? Is this not an Ascom compliant FW and should it not be reporting motion completion? I have always left mi delay setting at 0 (zero).
I have stayed with my imaging for the end part of tonight's run. Later I am going to open a separate thread re some observations. One thing I have noticed: filter change and focus change slowing down drastically as the night goes on. This may just be my set up - not particularly SGP.....but if anyone else notices this please say so, in case it is actually SGP.
Getting back to the filters.....if things do slow down after hours of imaging (with your set-up also....not just my gear) and the filter wheel takes too long to make an actual change....then perhaps this is when things hang as we have seen.....the FW does not actually get around to reporting move complete. I am clutching at straws maybe....this is so hard to nail down. One would have to look very carefully at the log if not watching things as they happen - but it may be evident in black & white.
Just for info - using the older filter wheel driver tonight and no hang or stop in the sequence......just seeing this drastic slow down in filter change as noted above.
