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 temperaturecompensating
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 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 fit a wide variety of refractor telescopes
Newtonian-BDS (NT): Includes Baader Versabase, for perfect fit onto most tube diameters.
Optional flat mounting base available soon
SC/HD-BDS (SC/HD): Includes adapter to fit all C14/C11/C9Ό/C8/C6/C5 OTAs
