Setup went well. Starting taking the remaining images of the Fireworks Galaxy. Then I woke up in time to check if SGPro started imaging the Trifid. Looked good. Went to bed.
Next morning, I checked the images. Fireworks looked good. Luminance of Trifid looked good:
I guess, the battery that powered the imaging equipment and the laptop wasn't fully charged and the camera or the USB hub dropped pixels.
After something major went bad every night, I decided to call it quits and not stay for a fourth night. Also, I was really yearning for a warm bed!
