2" BDS-RT Baader Diamond Steeltrack® Focuser

Baader Planetarium's 2" Refractor Diamond Steeltrack Focuser gives refractors a full 3" (76mm) of velvety smooth focusing travel. Easily adaptable to popular refractors.

  • Overall length fully retracted 80mm (backfocus length).
  • Drawtube is fully internally baffled and blackened to eliminate off-axis stray light.
  • 72mm dovetail receiver permits 360degree rotation of focuser with single-screw locking.
  • Optional adapters available to fit a variety of other refractors.

      All Baader Diamond Steeltrack (BDS) Focusers have the following specifications:

      Drive System

      • True diamonds form a micro-geared high precision drive system never accomplished before
      • In comparison to conventional crayford or rack & pinion drives, this micro-geared movement has zero backlash, zero cogging, and zero flexure
      • Diamond Steeltrack 2" focusers lift a payload of 6kg (13 lbs) straight up, without slipping, without excessive bearing preload (bearing preload can be increased further if necessary)
      • Bearing system utilizes unbreakable Instrument Grade Roller-Bearings instead of simpler Ball Bearings - handles higher loads with greater rigidity and accuracy. No Teflon-pads anywhere
      • 1:10 Stainless Steel fine-focus mechanism, ready for attachment of the optional Steeldrive temperature-compensating motor drive system
      • Detachable drive block assembly is reversible for right hand or left hand fine-focus operation and for attaching the Steeldrive motorblock onto Diamond-NT-Steeltracks for newtonian telescopes
      • Shortest possible mechanical design achieves optimum balance between focuser height (backfocus) and rigidity requirements
      • Zero shift locking knob to precisely stop any movement without affecting optical axis adjustment

      Focusing Drawtube

      • Each bearing individually adjustable for precise alignment of mechanical vs. optical axis
      • Ultra-hard subzero coated bearing races – precision milled and much harder than anodizing or stainless steel
      • Oversized 55mm inner clear diameter, to prevent vignetting, with anti-reflection knife-edge baffles

      Clamping System

      • S58 Dovetail ring-clamp built into focusing tube for accepting optional T-2 / M48 / M68 and other S58 direct-thread adapters to enable direct thread connection of accessories and cameras without 2" clamp
      • 2" eyepiece clamp with hardened bronze clamp ring (length of clamp: 12.5mm / ½") included as standard
      • Optionally available 2" Baader Clicklock-clamp w. integrated S58 dovetail (added length: 16mm / 5/8")
      • Two auxiliary threads (M60x1 and M55x0,75) cut into the RT & NT focusing-tube for attachment of dedicated field flatteners or focal reducers/correctors

      Excellente pièce d'équipement

      Selon moi, cette pièce d'équipement vaut le prix qu'elle m'a coûté. J'ai fait affaire avec David Astro (David Brodeur) et je ne le regrette pas, comme c'est toujours le cas. Très satisfait du service que j'ai trouvé impeccable.
