Midnight_Odyssey76 No, but it's a common way they fail when conditions aren't ideal. My longest Mosaic is about 110 minutes of total exposure time, but I've had a bunch of them fail around 20-25 minutes, having completed less than one full pass. They tend to have issues finishing off the top left corner for reasons I've explained in other posts.
ZWO will suggest it's due to clouds, trees, ground vibrations... when it's none of those things. All I can say is, it does help to get away from city lights more than you'd normally have to.
