Grid on top of image

Hi Sam

I have a new camera ASI071. when I take a picture after the camera gets cold I get a grid on top of the picture.

The grid disappears when I take a picture after the camera gets hot.

What is the reason for that grid on the picture and what is the solution ?

Sincerely

Uri Bezaleal

this is dew on sensor

please use the external desiccant tube and put dry desiccant inside

we also provide upgrade service for 071 camera

please hurry up if you wish to upgrade to 071 Pro
