Our Description

Drive System:

  • In comparison to conventional crayford or rack & pinion drives, this micro-geared movement has zero backlash, zero cogging, and zero flxure
  • 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 Tefln-pads anywhere
  • 1:10 Stainless Steel fie-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 fie-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-reflction knife-edge baffles

Clamping System:

  • S58 Dovetail ring-clamp built into focusing tube for accepting optional T-2 / M48 / M68 and other S58 directthread 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

Telescope Adapters:

  • Refractor-BDS (RT): Adapters available or under development to fi a wide variety of refractor telescopes
  • Newtonian-BDS (NT): Includes Baader Versabase, for perfect fi onto most tube diameters.
    Optional flt mounting base available soon
  • SC/HD-BDS (SC/HD): Includes adapter to fi all C14/C11/C9¼/C8/C6/C5 OTA’s
