Cleaning - ZWO ASI071 Series Manual

7. Cleaning

The camera is sealed and comes with an AR protect window to protect the sensor from dusts
and humidity. We don't recommend customer to open the camera for cleaning. The dusts can be
removed by post processing with flat frame.
To see the dusts, you just need to set up your telescope and point it to a bright place. A
Barlow is required to see these dusts clearly. Then attach the camera and adjust the exposure to
make sure not overly exposed. You can see an image like below if it's dirty.
