Hello All, I've recently acquired a Hassy, and I know i'm eventually going to want to do star trails, night exposures, etc. In the past, I've used a Speed graphic with a Sportsfinder, or the Sportsfinder in a Yashica. However, the hassy dosen't seem to have one of these, so I thought I'd ask how you all do it? Not just with a hassy, but with any camera when it's too dark to see what you're aiming and don't have a sports finder (can I get one though, with my 60mm?) If it helps, it's a 500CM and Distagon 60mm is what i'll probably be using for these shots, but hopefully there will be some techniques which work with other cameras too.
