Description

After drying out my desiccants to remove the moisture buildup many screws in the camera wouldn't tighten anymore as if they had been overtightened when manufactured. I've worked with zwo support to diagnose the issue and it's now on its way in for repair.

Wanted to share the results of the camera tilt adapter using only two out of the three screws. Notice how uniformly the stars have res halos on the bottom half and blue halos on the top half... Also notice the stars flaring outwards on the bottom two corners and the stars circling around on the top corner.

With the 135mm f2 lens (at f2) this shows the two different mis-focus regions caused by the tilt.
