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:
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.
Phillips Screwdriver
1/16" Hex-Head Wrench (Not required for NexStar 11 GPS)
