2" BDS-SC Baader Diamond Steeltrack® Focuser

Baader Planetarium's 2" SC Diamond Steeltrack Focuser gives Schmidt-Cassegrains 30mm of velvety smooth focusing travel. Easily adaptable to all popular SCTs.

  • Baader Diamond Steeltrack® (BDS-SC) for Schmidt-Cassegrains (incl. EdgeHD) with 30 mm focus travel
  • Minimum height (as supplied – incl. 2" clamp): 93 mm
  • Minimum height (with optional S58 direct-thread adapters): 80 mm
  • Focuser weight (as supplied – incl. 2" Klemme): 1.040 g (36.7 oz)
  • Includes 2" and 3.3" adapter to fit all C14/C11/C9¼/C8/C6/ OTA’s

      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
