Celestron Ultima Series User Manual

Tripod Balancing Platform (for Ultima 100 models)
This is used on Ultima 100 models to properly balance your spotting scope on top of a photo/video tripod.
To use the tripod balancing platform:
Mount the platform to the top of your photo tripod using the ¼"-20 threaded hole on the bottom side of the platform.
Attach your spotting scope to the platform using the ¼"-20 mounting screw located on the top side of the platform. Thread the mounting screw in as far as it
will go. Slide the attached spotting scope along the slotted cutout until your spotting scope is balanced on the tripod.
Tighten the locking ring to hold the spotting scope in place.
Maintenance
To protect your spotting scope when not being used, put on all lens covers and the lens cap to keep the optics clean and then put
the scope in the soft carrying case. If your optics could use cleaning, use an optics cleaning kit and follow the instructions.
