With a setup consisting of an ASI1600 main camera and an ASI178 secondary camera, no way to achieve more than thirty poses without arriving at an infinite loop of a given pose.
A stop, then immediate recovery causes a new looping from the first pose.

However, if I stop the ASI178, and I restart my series, then I see no problem.

This is obviously related to the cohabitation between the 2 cameras ZWO.
Indeed with a setup consisting of an SX694 and the ASI178 I have no problem.
Same with the ASI1600 alone without the ASI178.

Have you limited the USB bandwidth? Had troubles, too, when using 1600MM photo + 120MM guide....
What's a pose?

The nightly KStars release _might_ help if you're willing to give it a go

Sorry for the bad translation, I meant "capture" or "frame".

I have just collected the images of this night, and all have passed without problem
The only difference: I gave an old USB cable.
I had indeed changed both camera and USB cable. It is obviously my USB cable which is defective.

The incident is closed.
