Thanks all. Light pollution sure is a pain, here is a single 10 minute ISO200 sub. Thank goodness flatfielding removes the dust bunnies. I cleaned the sensor the next day.

To try and get some advantage over the light pollution I didnt use the UV/IR filter, the Hutech modded 350D only has clear AR coated glass on the sensor, thus allowing near infrared light in as well, adding slightly to the exposures.
