I have tried storing it in a plastic bag with dessicant or with the heater and it still happens.

Hi Grey, that looks pretty cool. You got no reflections there.
Regarding the camera. I leave mine opened in the case with the heatbox all the time when not using it. When I'm going to use it I get a hair dryer and blow warm aie inside and all the tubes, spaces I assemble between the CCD and the MPCC or filters. The body of my QHY8 is also taped around the outside to stop light leaks and air leaks. I also re-siliconed around the plugs to improve it and make it air-tight. Never had frost/dew problems since then, even with the hyperstar camera facing down.

I then ended up with blocky stars- is that what is called undersampling?
I would like to find an answer, as I'm getting ticked off and am considering selling the QHY8, or perhaps we need some collective pressure on QHY to help resolve the problem.

The squares are not undersampling. Not sure what it is.
