Dear ZWO,
Could you please do something with this kind of error when images are continuously discarded because of "Not enough stars"? I don't really understand this error at all, because it is only present when trying to shoot a few stars as Alkaid and Spica. It's OK that there are no other bright stars in the field of view near the object, but it is the same with ALL the stars which can be, however, captured normally without this error.
You can see in the following photos that there are other stars near the object, but it was very hard to capture them reaching at least a 3 minute exposure time, it took about half an hour or more:
