Last night, having learned how to set up and polar align, I tried to start a session for the first time.
After SharpCap polar align I went to NINA and wanted to start out by letting it get me through some flats/dark with its "Wizard".
But it reported a main camera download data issue, as in, no download data.
This morning I have brought the camera and laptop inside, where I hookup power (A/C) and a different data cable, a USB 2.0 instead of a 3.0.
But I can't get NINA to let me take a test exposure with the cooler not enabled and the telescope not connected.
I also have SharpCap, is there a simple way to take a test exposure and just confirm that there is not a problem with my ASI533?
If it was the cable, or just my newbie software issues, that would be a relief.
