Description
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 pre-load (bearing pre-load 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 Diamond 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 Diamond Steeldrive motor block
- 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
Multiple Adapters available for shortest possible connection to most cameras / eyepieces

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

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
- Over-sized 55mm inner clear diameter, to prevent vignetting, with anti-reflection knife-edge baffles
