I must admit that I had wondered about the glass on the front of my SBIG CCDs.
The number of "cosmic ray" hits that I get with my ST10XME is vastly higher than my ATIK camera. I know they are different CCDs but this shouldn't be a major factor. Also my home made genesis CCD with a kodak 0401E chip that is similar to the kodak ones in my SBIG cameras has very few CRH.
Does the cover glass emit small amounts of radiation?
