Using the LX65 with Two Optical Tubes
APPENDIX E:
The LX65 is equipped with a second dovetail
saddle to allow attachment of a second optical tube
assembly. The optical tube must have a Vixen-style
dovetail plate to attach to the LX65. The practical
weight limit for the second optical tube is 7 lbs.
Loosen the Dovetail Locking Knob and insert the
optical tube. Make sure the dovetail plate is at
against the saddle and tighten the Dovetail Locking
Knob.
Aligning the Second Optical Tube
You may need to make small horizontal and vertical
adjustments to the second optical tube’s positioning
so that both optical tubes are aligned to one another.

select a distant target such as a power pole during
the day or a bright star at night.
1. Center your target in the eyepiece of the main
LX65 optical tube.
2. Carefully rotate both Vertical Adjustment
Knobs in the same direction at the same time
(the front knob uses left-handed threads and the rear
knob uses right-handed threads). Turn the knobs
very gradually. Only a small amount of adjustment
should be needed so that the two optical tubes are
aligned vertically.
3. Check that the Dovetail Locking Knob is still
secure after the vertical alignment adjustment and
retighten if necessary.
4. Slightly loosen the Horizontal Lock Knobs.
5. Turn the Horizontal Adjustment Knob as needed
so that the target is centered in the eyepiece of
both optical tubes.
6. Retighten the Horizontal Lock Knobs. Check that
both optical tubes are secure with both Dovetail
Locking Knobs securely tightened.
NOTE: Always rotate Vertical Adjustment Knobs
in the same direction, at the same time, and with
the same magnitude.
Always take caution when making the vertical
adjustment and to support the OTA as needed.
Only small adjustment should be needed.
