[QUOTE=Lowell Goudge;242897]not with the digital.
the problem is that at 1000mm, and the crop factor, vibration is a nightmare. There are 2 problems, first is any tripod vibration and the second is that the T-Mount and attachment are prone to a little movement. I have now gotten a long lens stabilizer that should help this situation out a little and hope to test it soon.

I shot the moon tonite and found that i had to stay off the deck to prevent vibration (2second delay). i can imagine that another 4 inches in legth on this lens would be a huge problem. Heres the crop from tonites shoot, f8 at 125th; 2nd pic is pp in cs3. i am very pleased with the resolution on this lens:
