I would recommand a focal length of approx 150mm or less and exposure times of less than 10 seconds. Edit: suggest aiming for ~80mm and go from there.
My shots last night were mostly with the tracking turned off so that the foreground wasn't trailed, and the exposure times were between 2 and 10 seconds at 800ISO and between F/4 and F/10. It all depends on the stage of twilight as to when the sky background will over expose.
Hopefully you have a cable release or such, that's probably the most critical other factor I think.
If you had a tracking mount you could do longer focal length and longer exposures but you won't miss it in this case I don't think  |
Thanks Roger for the tips. Hopefully the clouds part on the western horizon and can get something decent. Have you had a chance to image Panstarrs with the astrotrac?
