Attempted to refocus on fainter stars - clouded over
Lost stars in camera.
Moved to Capella to refocus.
Returned to target.
Target was out of focus again.

This was because the focus of camera 2 was unstable in an upright position due to the weight of the camera. To fix, the camera was focused on other unidentified stars in the North East, and the focus was locked in place before returning to target.

Returned to target, refocused camera 1.
Took image with camera 1, exposure time 4s.
Took image with camera 2, exposure time 15s.

Images attached.
