I just purchased a new cooled mono camera the QHY163M. I did a test run to see if there were any issues. To my disappointment I see that there is a blemish spot that I have circled - Is this on the cover of the sensor or the sensor itself I cannot see anything when I look at the sensor/glass. Is this a concern and should I return the camera? I have attached three downsampled images which show that the spot must be located on the sensor or sensor glass because the spot has not shifted within the frame.
