About this product

Model:  baad_st-nt-diamond_2957230
Part Number:  2957230

Features Baader's unique 'Diamond form' micro-geared drive system for zero backlash, zero cogging and zero flexure. 

Fits Newtonian telescopes 8" inch and larger. (Will also fit most 6" Newtonians if the telescope's original focuser is a 2" type). 

Whilst the mounting plate has been optimised for SkyWatcher/Celestron/Synta reflector telescopes it can also be used to upgrade most other Newtonian telescopes. 

Diamond Form Drive System

  • 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)
  • Bearing system utilises unbreakable Instrument Grade Roller-Bearings instead of simpler Ball Bearings handles higher loads with greater rigidity and accuracy. No Teflon-pads anywhere
  • 1:10 Stainless Steel fine-focus mechanism, ready for attachment of the optional Steeldrive temperature compensating motor drive system
  • Detachable drive block assembly is reversible for right hand or left hand fie-focus operation and for attaching the Steeldrive motorblock onto Diamond-NT-Steeltracks for newtonian telescopes
  • Shortest possible mechanical design achieves optimum balance between focuser height (backfocus) and rigidity requirements
  • 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 anodising 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

Quality focuser
Monday, 31 December 2018  | 

The quality is far superior to the dual speed one I had on my 200P, which used to flop about when the scope was moved. Just waiting for a clear night to try it out.
I will say it comes with no instructions, I watched a video on how to do it on youtube, which helped but the holes did not match up with the ones on my scope. Luckily I'm quite handy at DIY.

Baader Diamond Steeltrack NT
Friday, 30 November 2018  | 

Recently purchased and fitted the Diamond Steeltrack NT to my
Quattro 12S and what an upgrade. No slippage or flexure whatsoever, the build quality is superb, carries camera, filter wheel and OAG with ease, a fantastic upgrade from the standard Skywatcher standard unit which is not up to the task of F4 imaging. I also fitted a DIY stepper motor to the focuser for imaging which works perfectly. As a test I sat 5.5kg directly on top on the drawtube and lifted it up and down vertically with zero slippage and perfect repeatability so Baaders capacity claim stands up. Unfortunately the mounting holes are not Skywatcher compatible thus requires redrilling the OTA but that's an easy task for anyone with basic mechanical skills. As usual first class service from FLO, a pleasure to do business with.

Beautiful piece of engineering

If you're used to stock focusers as I am then it's easy to appreciate how much better than the standard one that came with my Skywatcher 200P this is. So smooth and solid, lovely design and with no sign of slipping even without using the lock screw. Handles a CCD camera and filter wheel with ease.

The installation instructions on the Baader site are wrong though! The focuser is designed to replace the one on an 8 inch Newtonian, especially Skywatcher, and there's no way the attachment holes on the focuser line up with the existing holes on the tube - so you can't position the focuser using them. Also you need one set of shims to pack it out as well. Maybe it's an age/model thing - my old focuser was the single speed Crayford.

That said, it's still fairly easy to install.
