Thanks Matt - it's difficult for me to get to dark skies. I'm hoping to go to a local club's star gaze this weekend. In the meantime, last night I shot Markarian's Chain with a wider field. Used a 300mm lens on my Canon 40D @ ISO800. Five 4 minute subs, two darks, two flats stacked in DSS and processed in PSE4. Again used the Hutech light pollution suppression filter on the camera.
