HI

I image in suburban Sydney where light pollution is a problem. For the past year or so good clear skies are a rarity when clarity appears to be affected
by high atmospheric moisture. I find that to image object such as the Horsehead and Pleiades that I have to use 500sec images. I am using a modified Canon 400D, ISO 1600, light pollution filter, on a 200mm RC at f8. The 500sec images come out with quite milky and no amount of stacking or stretching etc can produce a decent composite. Shorter image durations just do not show much feint nebulosity. My thoughts are now wandering to getting a QHY8-L ccd camera. Would this give me significant improvement over the Canon 400D in current sky conditions?

Cheers Peter
