Meade Instruments LX850 - Manual (Page 3)

WARNING!
Never use a Meade ® LX850
Telescope to look at the Sun !
Looking at or near the Sun will cause
instant and irreversible damage to your
eye. Eye damage is often painless, so there
is no warning to the observer that damage
has occurred until it is too late. Do not point
the telescope at or near the Sun. Do not
look through the telescope or Finder Scope
as it is moving. Children should always
have adult supervision while observing.
Travel Screw:
The LX850 f/8 ACF optical tube assembly (OTA) is
shipped from the factory with the focusing mechanism
protected by a travel screw. This screw secures the
primary mirror in a fixed position during travel thereby
protecting the focusing mechanism from shock
damage. This screw is on the back cell of the OTA,
near the Crayford Focuser, and is identified by a dab of
red paint.
This screw must be removed before attempting to focus
the OTA. Failure in removal can result in damage to the
Crayford Focusing mechanism. Retain this screw for
future use as it is suggested that mirror be locked down
anytime the OTA is shipped.
Move the primary mirror to the travel position by rotating
the focuser knob counter clockwise until its travel limit
is reached. Reattach the travel screw and tighten until
firm. Do not over tighten.
