What causes redness in parts of an image

Hi all,

I have had a few images lately with red to the side of the images. Always the same side. Seems to get worse as the night goes on (I think). What causes this? Is it that my darks are not taken at the same temperature as the image? My camera is an ATIK 320E. I used a stack of images plus darks and bias frames...

(Yes - there is a dust bunny there too)...

Please shed some light on this for me...
