Well, I've tried pointing the scope at other objects and frankly a lot of
nebulas and deep sky objects are just fuzz balls unless you are
photographing them. The eye can't capture enough photons to make a good
visual. Thats why we need to take long exposures, so we can capture them, no?

Well, my main source of information is Covington's Astrophotography for the
Amateur.

I'm a computer programmer by nature. If I can point at object A now, why
can't I point at it now+5? I understand the rotational stuff, but if the
software is smart enough, it should be able to adjust for the
rotation. The problem, I assume is the software isn't smart enough.

Possibly not, but I'm not getting anywhere new with fixed tripod shots
either. I shot some stuff this week. I got some good 8-15 second
exposures of constellations, on my D1 (it was cold enough that the dark
current noise wasn't too bad). I shot some 3-5 minute exposures pointed at
Polaris on film so I have to wait and see what came out there. I'm hoping
for some nice star trails.
I guess I need to read Covington some more.
Thanks,
Rob
