I tried a 200mm lens at openings of 2.8 and 4, and an 85mm at 1.4 and 2.8. The best exposures seemed to be about 20 sec at 2.8. Any more than that, I started to see too much start trailing. If I had a clock drive on my tripod, longer exposures would have been possible, except that the brightness of the city sky creates a limit as too how far I could go. I think that 1 min. would have been the maximum possible. Dan C.
