7. Cleaning
The camera is sealed and comes with an AR protect window to protect the sensor from dusts
and humidity. We donât 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 itâs dirty.
The big dim spot on the image (at right ) are the shadows of dust on the protect window.
The very small but very dark spot in the image (at left) are the shadows of the dusts on the sensor.
The suggested way to clean them is try to blow them away with a manual air pump. To clean the
dust on the sensor you will need to open the camera chamber.
We have a very detailed instruction on our website:
