Baader Planetarium 2 Inch Steeltrack Crayford Focuser for Refractor Telescopes

Description

• The drawtube is equipped with massive steel rails as counter bearing for the adjustable travelling mechanism
• The counterpart for the Crayford driving shaft is a laser-cut plate made of stainless V2A steel instead of aluminium
• A stopper screw with turnable beared pressure pad blocks unintended travel even at high load
• All joints between drawtube and outer case run steel-on-steel with ball bearings. The results is a stress-resistant focuser suitable for heavy cameras
• All steel parts and gears are designed for long-term and motorized operation. The whole focuser is much more solid than standard Crayfords whose steel/aluminium pairings wear in with the time
• Heavy 1:10 reduction gear, completely machined from V2A and hardened steel
• Essential for CCD and DSLR photography: No tilted focal planes because the whole bearing system is designed completely adjustable
