I think you would have lots of trouble with longer exposures and your mount would have to have near perfect tracking. I thought the best you could hope for was about 2 arcsecs/per pixel due to atmospheric turbulance, even on a very good night. Still they claim seeing is about 1 arcsec if you are sitting on top of a great big mountain like the himalayas .
