LX600 12" Primary Mirror Lock
They forgot to pack one feature into the feature packed LX600 12" SCT:
A mirror lock! Most SCTs suffer to some extent from mirror shift, flop,
drift, settle, etc, even while just tracking. Focusing and slewing adds
to the list of words that describe the behaviour of a heavy, unruly mirror.
Fortunately Meade provides a hole and bolt to lock the primary mirror for
shipping the LX600 12", just like in the original LX200 Classic scopes.
With the shipping bolt removed, our mirror lock clamps to the rear cell
and connects to the primary mirror cell thru the shipping bolt hole.
When properly installed and aligned, a twist of the lock knob stabilizes
the position of the mirror.
No modification of the scope! The lock assembly is mounted and aligned
with the supplied Allen wrench. And Mike Weasner has supplied great
instructions for installation, adjustment and use. Many thanks to Mike
for inspiration, testing and feedback for this slick gizmo!
Cautionary note: The mirror lock really locks the mirror! Be sure to
unlock before turning the focus knob! Forcing the focus knob with the
mirror locked will void at least two warranties, just before something
The mirror lock can be completely removed from the scope in seconds
for transportation or shipping, but it would require realignment when
being reinstalled. So, we supply a locking bolt and capnut so the mirror
lock can stay on the scope and double as a transport lock.
