Baader 2" NT Steeltrack Precision Crayford Focuser for Newtonian Telescopes with 30mm Back Focus and Ultra Low Profile
(Shown with optional Pushfix 2-inch to 1.25-inch Low Profile Reducer)


There is a Steeltrack® Crayford Focuser available to fit nearly all telescope types including Refractors, Newtonian telescopes and SCTs (Schmidt-Cassegrain Telescopes) in both 2-inch and 3-inch sizes. If you have a different from above, special telescope then it's very likely that a Steeltrack® Crayford Focuser can be adapted to it through the available various extensions and adapters.
 

 

All Baader Steeltrack® Premium Crayford Focusers have the following characteristics in common:

 

  • Highest precision and quality from Baader Planetarium.
  • A drawtube locking screw with rotatable pressure plate blocks unwanted longitudinal movement or flexure when the Crayford focuser is loaded with a heavy eyepiece or camera.
  • The eyepiece holder is fitted with a 2" or 3” clamping device (depending on the model). A brass/bronze clamping ring/compression ring protects your eyepieces and accessories from falling out as well as scratches and marking.
  • Contrary to simple Crayford focusers, instead of aluminium, a laser-cut hardened and polished stainless steel (V2A) plate serves as a driveway for the precision ball bearings.
  • The entire extract is much more stable than simple Crayford focusers where the steel ball bearings can wear out the aluminium ways thus making the movement softer, lousier and less accurate with time.
  • Precision 1:10 reduction gearing in professional quality completely made of V2A stainless, hardened and polished steel. The Precision Pinion Drive runes on precision laser cut hardened and polished stainless steel way. No backlash.
  • The inner drawtube surfaces are provided with antireflection and high-quality blackened ribs to eliminate stray light reflections.
  • Especially important for CCD and DSLR Photography: No more blurry corners, since the storage of the barrel sleeve is designed so that the optical axis of the focuser can be adjusted if necessary for precision.
  • All Steeltrack® Focusers are designed for long-term operation and motor drive (permits addition of a motor drive that will be available in 2010). 
  • The reducer of the focuser is prepared for a fine drive by a motor, later to be acquired by means of belt drive.

Hole positions:

1. distance between two holes alongside: 54mm (one hole is closer and another one is further away from the primary mirror...)
 
2. distance between two holes opposite each other: approximately 90mm (one hole is on the side of the knobs, the other hole is on the side where there is no knob)
 
The latter is much more difficult to measure as there is an angle between these, so from the top the distance is about 100-102mm, but from the bottom it's about 90mm
 
Drawtube diameter: 58mm
