Focusing screen can make a big difference here. My Meade 1000/11 focuses 
easily with a 1-7, certainly easier than a 2-4. The split image and 
microprisms of the regular, 'for most lenses' screens are useless with 
it. Still pretty shallow DOF for fast moving targets, but pretty easily 
usable for most subjects. I recently got a 1-8, but haven't tried it on 
the 1000mm yet. I need to sit down with tripod and 2 bodies to compare 
1-7 and 1-8. The hawks are hanging around the nest across the street 
again, so I may have subjects soon.

The .Celestron can of course, also be used as a super telephoto lens 
with a simple adapter.
