I just used the ST7E + CCDOps and centered the guidebox on the comet nucleus.

No-brainer (once its all hooked up, configured, calibrated, focused, film wound, timer set, etc etc etc)

Hopefully tonight (if weather gods allow it) I'll be shooting w/ provia 400F.

And yes, the tail does go out of the fov, but with the skyglow its washed out.
