INSTALLING THE DELUXE LATITUDE ADJUSTER
Latitude Adjust Assembly Installation.
• Remove the screws marked A in figure 2-5 from both sides of the wedge.
• Place the wedge in front of you upright and with the Celestron logo facing you. Place the wedge on its
left side. There should be a hole right next to the fourth hex head screw. This is where the azimuth
adjust screw will go. Loosen all of the hex head screws on the side of the wedge which is upright now.
Loosen them about three turns. There is no need to remove them completely.
• On the back of the tilt plate there are four 1/4-20 tapped holes. Place an angle bracket on the lower set
of holes with the bracket facing up. Use two of the 1/4-20 screws to attach the bracket.
• Take the latitude adjust assembly, shown in figure 2-4, and place one end of the swivel pin in the hole
of the mounted angle bracket. Now take the second angle bracket and slip it over the exposed side of
the swivel pin and mount the bracket.
• The crossbar needs to be adjusted so that it lines up with and slips into the recess on the inside of the
wedge side plate. Rotate the cross bar on the adjust screw until it approximately lines up with the
recess on the lower side of the wedge. This is the one inch diameter counter sunk hole that looks silver
since it is not coated. It is facing up at you since the wedge is on its side.
• Since the upper plate is loose it can be moved to allow the crosssbar to fit into place. The upper and
lower ends of the crossbar should fit into the recesses on the sides of the wedge. If the top side doesn't
quite fit, rotate the adjust screw till it does.
• Tighten all the screws of the side plate and replace the screws marked A being sure to tighten down the
slotted Latitude Support Arms in figure 2-5. Be sure the nylon washers are between the Latitude
Support Arms and the side of the wedge.
Azimuth Adjust Assembly Procedure
• Remove the block assembly from the threaded rod of the Azimuth Adjust Assembly.
• Remove the collar from the threaded rod by loosening the set screw.
• Attach the block assembly to the bottom of the baseplate of the wedge using the 10-24 x 3/4” screw.
The tapped hole should be facing the toward the left side of the wedge if the wedge is upside down. Do
not tighten the screw all the way. The block assembly should be able to slide back and forth.
• Put one nylon washer on the threaded rod and place the rod through the hole on the side of the wedge.
• Once the threaded rod is through the side of the wedge, place the other nylon washer on and then the
lock collar on.
• Now thread the threaded rod into the tapped hole on the side of the block assembly.
• Push the handle of the threaded rod flush against the side of the wedge and place the lock collar against
the inside of the wedge.
• Tighten the set-screw in the collar.
• Now if you rotate the threaded rod, the block assembly should move. If it is hard to rotate, then loosen
the screw holding the block assembly to the baseplate of the wedge.
