High ISO on older sensors is going to produce noisy shots, unfortunately. I wouldn't use anything over 400. You can remove some noise later in post-processing (as long as it's not done at the expense of sharpness and level of good detail). Or you secure your camera on a solid sturdy tripod, protect it from wind, increase exposure time to 20-25 sec and shoot wide-open with a super-fast lens at 1.2 or 1.4. But as you get over 10 sec, Earth movement comes into play and stars start producing trails. Night shooting has a lot of variables. But a good shot is quite achievable even using older DSLRs.
