The Meade
LX200 Classic, shown above piggybacking the Tak
FSQ-106, is a Schmidt-Cassegrain GOTO scope useful
for a wide variety of applications including visual,
astrophotographic, and for use in an observatory. I
modified this scope myself with upgraded declination bearings
in the fork arms to give frictionless movement. This
mod allows for better dec performance with heavier
piggyback loads and less pressure on the drive for basic
use.
While
the LX200 is capable of piggybacking some good sized
loads, doing so with 4" or larger refractors are
not recommended
for astrophotography, especially in polar alignment
mode when using an equatorialwedge. It will work for visual observations if the LX200
is in its ALTAZ configuration, but it should not be
considered an worthy alternative to a solid German Equatorial
mount. In general, these fork mounted scopes are
not stable enough to hold excessive amounts of weight,
especially in the wind. Once the fork arms start
to vibrate, an oscillation develops that take many seconds
to settle, if at all.
As
for the Meade Superwedge, it cannot recommend it for
astrophotography due to flexure issues. Any one
of the third party wedges, while more expensive, would
be better alternatives. I would also recommend
an upgrade to the larger Super Field Tripod that is
standard with the 12" scope, or foregoing the tripod
altogether and placing the SCT on a permanent pier.
The standard tripod that comes with the
10" LX200, especially when used with the Superwedge,
is a large source of vibration and instability when
doing astrophotography.
