Attaching your Guide Camera
The 50mm Guide Scope can attach to your guide camera either by 1.25” slip fit connection
or a T-thread connection. Cameras that only have a 1.25” nosepiece, or camera bodies that
are 1.25” in diameter, can fit the 1.25” holder at the back of the helical focuser and are se
-
cured in place with the thumbscrews. The Meade LPI-G series cameras attaches this way.
Cameras with T-thread connections can thread directly to the back of the helical focuser.
To attach by T-thread connection, remove the 1.25” nosepiece from the guide camera (if
necessary), and thread the camera body to the back of the Helical Focuser on the 50mm
Guide Scope.
Some camera configurations may have difficulty achieving focus when attached directly
to the helical focuser. If this problem occurs, use the included extension tube between the
focuser and camera to allow your camera to reach the focal plane.
1. Thread the 1.25” Extension Tube to the back of the helical focuser.
2. Insert the 1.25” nosepiece of your guide scope to the 1.25” opening on the Extension
Tube and tighten the two thumbscrews, or, thread the T-threads on the guide camera (if
equipped) to the T-threads on the back of the Extension Tube.
Focusing
The Meade LPI-G and LPI-G Advanced cameras will reach focus when used with the 1.25”
Extension Tube. Different guide cameras may require removing the extension tube to reach
focus. Locate a bright star and center it using the Adjustment Thumbscrews. If necessary,
you can use a standard 1.25” eyepiece to help locate a star before installing your guide
camera. Rotate the Helical Focuser until the star comes into focus. It might require several
turns of the helical focus knob the first time you reach focus. When focused, tighten the
Focus Lock Thumbscrew.
Additional focus adjustment can be made by loosening the Objective Focus Lock, then ro
-
tating the objective lens assembly, however this is not necessary unless you need additional
focus travel.
