Focuser Diamond Steeltrack BDS-RT 2"

Real diamonds form a high-precision, micronised gear system – that's what makes the Diamond Stelltrack so unique!

Unlike conventional Crayford or rack and pinion drives, the micronised gear of this focuser ensures completely smooth movement, completely free of slippage and twist!

Additional features:

• Diamond Steeltrack focusers have a vertical load capacity of 6 kg in the basic setting without slipping and without strong bearing preload (this can even be increased if necessary).
• The bearing system includes indestructible, 10 mm wide roller bearings instead of narrow ball bearings, allowing heavier loads to be carried with maximum precision and torsional rigidity (completely without Teflon).
• 1:10 reduction gear made of stainless steel, prepared for optional Steeldrive motor drive using the toothed fine drive knob for the Steeldrive toothed belt
• Removable drive block for left- or right-handed fine focusing and for connecting the temperature-compensating Steeldrive motor block
• Shortest mechanical design, maintaining the optimum balance between minimum overall length (= gain in back focus) and maximum rigidity
• "Zero-Shift" axis brake for adjusting the braking effect depending on the instrument load – without pressure on the extension tube

Adaptation to telescope:

• Internal connection: M60 thread
• External connection: M68, S88
