Refractor Focuser 2" Rack and Pinion
http://www.gs-telescope.com/admin/disk/Focuser/gs300-r&p.jpg
Art No.: FC38001- 2" R&P Focuser
A very strong and precise 2" focuser for refractors, the metal focuser drawtube is guided by three strips of Teflon and with 117mm focus travel. Shifting and friction can be adjusted easily. An adaptor from 2" to 1.25" is already included, you will still be able to use your 1.25" eyepieces or Barlow lens.
On the top of locking thumbscrew will tightly secure focus for astronomical imaging even use the heavy Camera install with this focuser. Also this 2" focuser has a mostly slide finder quick exchange device.
Precision Crayford style 2" Focuser for Newtonian Telescopes
http://www.gs-telescope.com/admin/disk/Focuser/gs880-crf.jpg
Art No.: CRF001- 2" Refractor Craford Style Focuser
This advantage of the Newtonian Crayford design focuser, constructed of strong aluminum with a black anodized finish, the drawtube glides on 4 bearing wheels with 40mm travel, a built-in tension knob for adjusting the "feel" to match your preference to gives zero image shift and zero backlash, offer ultra smooth and finely adjustable.
The friction can be adjusted with a large thumbscrew, a second thumbscrew can lock the focuser tightly in position. Feature 2" brass compression ring, adaptor from 2" to 1.25" with brass compression ring and 2" filter thread.

Art No.: M-CRF230- 10:1 Micro Edge 2" Craford Style Focuser
The focuser is the most "visible" part of any telescope with the exception of the optics themselves. You touch the focuser all the time, the focuser is responsible for holding your eyepieces or camera in position and moving them precisely into focus in the first place. This way ultra-precise focus motion is possible for both visual and particularly photographical applications.
The features:
* Load capacity up to 2.7kgs
* Ultra smooth focus motion with 10:1 Microfocus knob
* Constant movement
* 2" compression ring
* 2" to 1.25" adaptor with compression ring and 2" filter thread
Aside from this feature the same specifications apply as with the regular version of the above Newtonian Crayford style focuser.

Art No.: M-MLP230- 10:1 Micro Photographic 2" Craford Style Focuser
The main field of use is of course astro imaging. Here a very smooth 22mm travel, high precision focuser is essential for the overall success of your astro photographical efforts. This focuser will solve the focusing problems with standard Newtonians that frequently don't have enough intra-focal focus travel.
