{"product_id":"ac0054067","title":"Baader Diamond Steeltrack BDS-NT 2\" Focuser","description":"From the renowned brand Baader Planetarium, the BDS-NT 2\" Diamond Steeltrack Focuser for Newtonian Telescopes with 40mm Focus Travel is a durable and high-quality piece of astronomical equipment. This innovative focuser is designed with a true diamond micro-geared high precision drive system, a first in the industry. Unlike conventional crayford or rack \u0026amp; pinion drives, this advanced system eliminates backlash, cogging, and flexure, ensuring smooth and precise adjustments.The Diamond Steeltrack 2\" focuser is capable of lifting a payload of 6kg (13 lbs) vertically without slipping, thanks to its robust bearing system that uses unbreakable Instrument Grade Roller-Bearings. This superior system offers greater rigidity and accuracy, handling higher loads without the need for excessive bearing preload.Equipped with a 1:10 Stainless Steel fine-focus mechanism, this focuser is ready for the optional Diamond Steeldrive temperature-compensating motor drive system. The drive block assembly is detachable and reversible, allowing for both right and left-hand fine-focus operation.The BDS-NT 2\" Diamond Steeltrack Focuser boasts the shortest possible mechanical design, striking the perfect balance between focuser height (backfocus) and rigidity requirements. It also features a zero shift locking knob, allowing you to stop any movement precisely without affecting the optical axis adjustment.The focuser's clamping system includes an S58 Dovetail ring-clamp built into the focusing tube. This allows for the direct thread connection of accessories and cameras without a 2\" clamp. The focuser also comes standard with a 2\" eyepiece clamp with a hardened bronze clamp ring.The focusing drawtube of the BDS-NT 2\" Diamond Steeltrack Focuser is designed with individually adjustable bearings for precise alignment of mechanical vs. optical axis. The ultra-hard subzero coated bearing races are precision milled and significantly harder than anodizing or stainless steel. With an oversized 55mm inner clear diameter, this focuser prevents vignetting and includes anti-reflection knife-edge baffles for optimal performance. In summary, the BDS-NT 2\" Diamond Steeltrack Focuser for Newtonian Telescopes with 40mm Focus Travel is a user-friendly, stylish, and innovative solution for precise telescope focusing.","brand":"Baader Planetarium","offers":[{"title":"Default Title","offer_id":55217225793875,"sku":"AC0054067","price":792.63,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0980\/2294\/9203\/files\/File_13b3c8d2-c26b-4a71-9bc2-efa6b44f621e.jpg?v=1791242473","url":"https:\/\/shopyourproduct.com\/products\/ac0054067","provider":"Shopyourproduct","version":"1.0","type":"link"}
