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
