Starlight Instruments Feather Touch Micro Focuser for Celestron CPC-9.25

 

If your telescope is less than a few years old, check the style of the back cell to see which version of the Feather Touch® SCT Micro Focuser you need: If your telescope has a flat back (left picture), you need the standard "C" Micro Focuser. If your telescope has a triangular pattern on the back (right picture), you will need the "CPC" version of the Micro Focuser.

Starlight Instruments is proud to annouce that with the coordination from Dean Koenig from Starizona that on July 27th 2012 one of the FTM-CPC9.25 micro focusers will have landed at the International Space Station on a brand new Celestron C9.25 Edge HD.

Installation Instructions:

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.

  • Feathertouch SCT MicroFocuser
  • Spacer plate
  • (3) M3-14 Hex-Head Screws
  • 2mm Hex-Head Wrench

 

Additional Tools

  • Phillips Screwdriver
  • Wrench 1.50" Adjustable

 

Step 1 - Remove Focus Knob


Starlight Instruments Feather Touch Micro Focuser Celestron Step 1

 

Begin by removing the black rubber focus knob from the scope.  This knob simply pulls off the brass focus cylinder.


 

Step 2 - Remove focus Assembly Cover


 

There are 3 small Phillips-head screws which hold the orange focus assembly cover in place.  Remove these screws and take off the flat cover plate, exposing the inside of the focus assembly.

 

Step 3 - Move Mirror Back to Expose Screw


 

Rotate the brass portion of the focus assembly clockwise.  This will bring the mirror back and expose the threaded portion of the focus shaft.  At the tip of this threaded bolt will be a small Philips-head screw.  Remove this screw, but keep it handy as it will be reinstalled later.

 

Step 4 - Remove Focus Bearing Assembly


 

Rotate the brass portion of the focus shaft counterclockwise.  This will unthread the brass cylinder and bearing assembly from the threaded rod.  Remove these parts entirely (you will have to turn the brass shaft quite a few times to remove it).

 

Step 5 - Remove Stop from Microfocuser


 

Unthread the stop from the end of the MicroFocuser.  This stop prevents the telescope mirror from falling off the baffle tube inside the  telescope.  Thread the stop onto the focus shaft of the telescope.  Be sure to thread the stop on far enough that the end of the threaded rod is exposed.

 

Step 6 - Reattach Screw


 

Thread the screw back into the end of the focus shaft.

 

Step 7 - Attach MicroFocuser to Stop


 

Thread the MicroFocuser into the brass stop.  Hold the stop with a wrench and the black focus knob with the other hand to tighten the stop.  This stop MUST be tight to secure the MicroFocuser to the focus shaft.

 

Step 8 - Attach SCT MicroFocuser


 

Use the three included screws to attach the SCT MicroFocuser to the telescope.  You are now ready to head out under the stars!  Use the black knob for coarse focus and the brass knob for fine focus (10:1 ratio).  Note that the telescope will likely be pretty far out of focus, so you may need to turn the focus knob quite a few times to reach focus.
