Installation Instructions – Celestron 11” Telescopes

Important: The telescope optical tube must be positioned horizontally before removing the original focus assembly. If the telescope is not horizontal the primary mirror could move during the installation.

Required Tools:	Phillips Screwdriver
	1/16” Hex-Head Wrench (Not required for NexStar 11 GPS)

Step 1 Remove Focus Knob

NexStar 11 GPS telescopes have a rubber knob which can be pulled off. Older 11" telescopes will have a metal focus knob which must be removed using a 1/16” hex-head wrench to loosen a small set screw. Once the knob is removed you will see the brass focus shaft as shown below.
