Took this last night, tough ask from my light polluted site. 14 x 10 mins ISO200, modded 350D no filters so near IR light recorded as well, 10 inch f5.6 hand guided.

Been doing this myself for a few outings now - only get around 1hr at a time given my trees. It actually responds quite well to the 8300 CCD chip - better than I expected, and given the amount of background noise still, it's brighter than I thought.
Gonna be a long time till I show mine. Might not even get 8hrs this season before its too late for me.
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.
