Product Description

Baader steeltrack dual speed 2" steeltrack focuser for Newtonian Telescopes, ultra low profile design with 30mm of back focus. Includes a universal adaptor suited to most tube diameters and sits a minimum 50mm height above the tube when fitted.

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).

Further details

The 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. The 1:10 Stainless Steel fine-focus mechanism, ready for attachment of the optional Steeldrive temperature-compensating motor drive system, see related products below. The detachable drive block assembly is reversible for right hand or left hand fine-focus operation and for attaching the Steeldrive motorblock onto Diamond-NT-Steeltracks for newtonian telescopes. Shortest possible mechanical design features achieve optimum balance between focuser height (backfocus) and rigidity requirements and a zero shift locking knob to precisely stop any movement without affecting optical axis adjustment.

Focusing Drawtube:
Each bearing individually adjustable for precise alignment of mechanical vs. optical axis
Ultra-hard subzero coated bearing races – precision milled and much harder than anodizing or stainless steel
Oversized 55mm inner clear diameter, to prevent vignetting, with anti-reflection knife-edge baffles

Clamping System
S58 Dovetail ring-clamp built into focusing tube for accepting optional T-2 / M48 / M68 and other S58 direct-thread adapters to enable direct thread connection of accessories and cameras without 2" clamp
2" eyepiece clamp with hardened bronze clamp ring (length of clamp: 12.5mm / ½") included as standard
Optionally available 2" Baader Clicklock-clamp w. integrated S58 dovetail (added length: 16mm / 5/8")
Two auxiliary threads (M60x1 and M55x0,75) cut into the RT & NT focusing-tube for attachment of dedicated field flatteners or focal reducers/correctors

Customer Reviews

10/10  Solid focuser worth the money  I have a 12 inch Revelation Dob and decided to upgrade the focuser as i'm now using heavier better quality eyepieces. Harrison telescopes delivered the item very promptly and well packaged. It has a top quality feel and smooth action. It holds focus with heavy eyepieces very well. Worth the money.  (17/05/2019) Steve - Walsall
