Baader Diamond Steeltrack® Focuser

General Specifications for all Baader Diamond Steeltrack^® (BDS) focusers:

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 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
