Hi,

I just got my new camera and tried it out on Jupiter. There is a green dot near the centre of the captured video frames which I am assuming is a faulty pixel. It spoils the animation I made because there is a green dot dancing around in space. Is this normal or should I return the camera?

Hello,
       It depent on the gain and also the exposure time. More high gain and more long exposure time you will see more hot pixels. Also the temperature is a reason.

       If you set to 30ms and gain =0.  There is such pixel appears , We can consider have a replacement.  Otherwise you can use some defect tools to process it.

Hi,

Thanks for the reply but I decided to return the camera for a refund.
