I continue to follow this issue here instead of reopenning because this is probably not exactly the same issue.

This is strange, for the first two series between autofocus starting at 20:49:34 and 21:26:32 there is two wrong exposure starting before settling, followed by 5 good exposure that waited for settling.
For the third series starting at 22:03:28 there is 6 wrong followed by 1 good.
The last one started by a wrong exposure you aborted.

Can you upload the PHD2 debug log for this session so I can see exactly when the settling message where send?

Thank you for the files.
Unfortunately I cannot find what is wrong here. I try to reproduce your sequence but for me it always wait for dithering.

I make a test version with a message that detail the condition of the dithering wait loop.
Can you download and install this test version before to make a new test and send me the CCDciel log:

The weather hat not changed yet, so I am looking forward to image until midnight, but the test version you provide is not usable because of a new issue, not happend before.

Autofocus works only once, than it failed. I restarted ccdciel, but the behaviour was the same. I want to continue my sequence so I deinstalled this version an revert to the previous.

Sorry for this error I make when trying to improve the stop of a sequence.
This is fixed by:

You can install the new test version from:

The good new is that all the exposure waited for dithering in your last log.

I will try your built 1158 at the next clear evening. Now it is cloudy here.

Half the night it was perfect clear. I grab your provided version and made a sequence. I cannot see the issue anymore, but this must not be representative.

Here is the log. At 2h I got up from bed and pointed the scope to another target. At 4 it must have been clouded.
Maybe you can have a look at my issue with VirtualMoonAtlas.

Yes, we cannot be sure because the condition that produce the error the last time is not know.
I keep the additional message but I change it to be written only in the log file to not mess the console log.

Sorry, I forget to look at VMA issue this last days, I reply now.

Sorry Patrick,
in my recent session, the issue appeared again.
I hope the log helps. I had to restart CCDCiel to continue my sequence.

Yes, very good. your log nicely show the problem.
The bad guy is "FStopGuiding=True"

The sequence that produce the error is:
- at the end of the flat sequence the program set this value as part of "Stop autoguider" at 19:48:52
- you start the autoguider directly from phd2 so this value "FStopGuiding=True" is not reset
- at the start of the sequence the autofocus procedure just pause the guiding, this again not reset the value
- guiding resume
- dithering exit immediately because of this value, he think you stopped guiding now and it must not wait for settling anymore.

This is fixed by resetting "FStopGuiding=False" in the Pause and Dither command:

New version 0.9.43 is compiling now and will be available in 30 minutes.

I close the issue now but please reopen if you get it again.
I let the extra trace message in place for a few more week.
