I have noticed it on the darks as well,HOughy.

Here is a image that is a stack of subs and darks (four minutes each).I have manipulated the image to show the artifacts along top.I am told the long 'dark ridge' is from the light going through the view finder,but still not sure what the 'pink' is-is it amp glow?? or caused from something else that needs to be addressed.

Assuming the 'long dark' ridge' was caused by light coming through the view finder-that can be solved fairly simply.The 'pink' is much less noticeable after the darks have been added in DDS.Are there any other thoughts on this 'pink' splodge and how it can be eliminated??

I have non of these things when using 50D.

Thanks for any suggestions-Chris
