Anybody tried them and had any success with dealing with the noise?
How long have you been able to keep the lens open?
The d70 was 30 min of course since it didn't have the 10 pin terminal. With the D200 (and 2 batteries in the vert. grip) I think I've done about 90 minutes without running out of juice. Chris (cgaengineer) and I talked about this awhile back and he was going to pursue the limits of this further, but I never heard what he came up with so you might pm him and see how far he was able to push the batteries.
Glad I can help out, Thom. I plan on doing a lot of star trail images up at the lake this summer. The city is far too bright for this stuff.
We should have a time-lapse contest at the end of the summer!! :biggrin:
