Up at the College of San Mateo where I teach students the fundamentals
of CCD imaging we use a 10" LX200 OTA on a Losmandy G-11 mount.

The mount is much more stable than the fork mount on my LX200 at my
observatory from a tracking standpoint. This allows us to image at F/10
on a steady evening and get great results. The best I can do with my
fork mount is image at f/6.3 and the tracking results are as good as the
G-11 at F/10.

Piggybacking a 4" Refractor would be pushing the mount to its limits,
but I think it could handle it if you balance just right.

Thanks for all your responses. I'm still curious as to what people
think
about switching from a fork to EQ mount, say if I take my 10"LX200 OTA
and put it
on a new or used Celestron CGE 1400 or Losmandy G-11 mount. Would such
an EQ
mount solve the problems we've discussed, and could they handle a
piggybacked
4" refractor?
