Designed to give the perfect image field when imaging with your Altair, Orion or Astro Tech 10" or 12" Ritchey Chretien, by making the focuser completely orthogonal to the telescope's optical axis.

Adjustment to fractions of a millimeter are possible for a perfectly flat field with optimal off-axis image sharpness. No more hunting the "sweet spot" for your particular setup. The focuser collimation adjuster is ideal for use with larger CCD chips (APS and above) as well as field flatteners and reducers, where deviation from the focal plane edge is more critical.

The Camera / Focuser Tilt Adjuster fits between the focuser and telescope. It can be adjusted in real-time for best results, using the easily accessible push-pull collimation screw system at the sides. It will not foul the standard RC focusers, nor the Starlight Feather Touch focuser upgrade. For the perfectionist, it's possible to use CCD Inspector to derive the exact amount of focal plane tilt as a numerical value, and to adjust it out completely.

The Focuser Collimation Adjuster adds 15mm to the optical path.

Mounting the focuser collimation adjuster is easy:
1) Remove the focuser.
2) Screw on the collimation adjuster.
3) Re-attach the focuser or RC focuser extension tubes, should you require them.
4) Use an Altair v2 Laser Collimator and Altair Self Centering Adapter to adjust the push-pull screws, placing the laser beam on the secondary mirror centre-spot.
5) Now you can fine-tune using the CCD camera preview mode or CCD inspector.
