Where precision and durability meet, the BDS-SC 2" Diamond Steeltrack Focuser is a high-quality, innovative accessory designed specifically for Schmidt-Cassegrain and EdgeHD Telescopes. This stylish, user-friendly focuser boasts a 30mm focus travel, ensuring smooth and precise focusing for your astronomical observations.The BDS-SC 2" Diamond Steeltrack Focuser is equipped with a true diamond micro-geared high precision drive system, a first of its kind. This system offers zero backlash, zero cogging, and zero flexure, outperforming conventional crayford or rack and pinion drives. The focuser can lift a payload of 6kg (13 lbs) straight up without slipping or excessive bearing preload, thanks to its robust bearing system that utilizes unbreakable Instrument Grade Roller-Bearings instead of simpler ball bearings. This ensures higher load handling with greater rigidity and accuracy.The focuser features a 1:10 Stainless Steel fine-focus mechanism, ready for attachment of the optional Diamond Steeldrive temperature-compensating motor drive system. The drive block assembly is detachable and reversible, allowing for right or left hand fine-focus operation and for attaching the Diamond Steeldrive motor block.The BDS-SC 2" Diamond Steeltrack Focuser is designed with a short mechanical structure to achieve the perfect balance between focuser height (backfocus) and rigidity requirements. It also includes a zero shift locking knob to precisely stop any movement without affecting optical axis adjustment.The focuser's clamping system includes an S58 Dovetail ring-clamp built into the focusing tube, enabling direct thread connection of accessories and cameras without a 2" clamp. It also comes with a 2" eyepiece clamp with a hardened bronze clamp ring. The focusing drawtube of the BDS-SC 2" Diamond Steeltrack Focuser is adjustable for precise alignment of mechanical vs. optical axis. It features ultra-hard subzero coated bearing races that are precision milled and much harder than anodizing or stainless steel. The oversized 55mm inner clear diameter prevents vignetting, and the anti-reflection knife-edge baffles ensure optimal performance. In summary, the BDS-SC 2" Diamond Steeltrack Focuser is a durable, high-quality, and user-friendly accessory for Schmidt-Cassegrain and EdgeHD Telescopes, designed to enhance your stargazing experience with its innovative features and superior performance..
