yeah, I could have given it more room on the right, but . . . was a very difficult set-up, couldn't move back to give the shot more breathing room, couldn't pan more right without losing the trails around Polaris, etc. Also, it can be a little difficult setting up in the dark! Oh well . . .
dennismock: I shot this somewhere in the realm of f/8. The adapter is made by a fellow FMer, here's his site: http://www.16-9.net/nikon_g/
The adapter has focus confirm but autofocus does not work. Also, the aperture has to be set manually (which is not a problem for me because I only use the lens for landscape work). BTW, the exposure was 30 minutes, not 30 seconds.
