Baader Diamond Steeltrack Newtonian Focuser

Baader Diamond Steeltrack Newtonian Focuser

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

  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

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).
