Skywatcher 150/750 back cover for a 80mm fan to avoid dew

The backplate stops light to enter in back part of the telescope during flat acquisition and helps to avoid dew

It's designed for a common 80mm fan. I use a USB powered one with three levels of fan speed.

If you want, you can clue the cable holder on one of the clips to have a better cable management.

No requirements for this print

It is better printed in black filament. I used PLA/ PLA+
