Product Questions

Please, where in this focuser should my f/6.3 Celestron focal reducer (CFR) go? Currently, my imaging train would be:
C11 --- (¿CFR?) --- BDS-SC --- (¿CRF?) --- ASI174

Thanks,
Martin.

Do you think that 2" BDS-SC Focuser can replace the Zero Image Shift Microfocuser on 10" LX-200-ACF (GPS + AutostarII / Dated 2009) from Meade ? Or can you propose another solution with fine-focus mechanism, even it is in manual mode ? Thank you very much for your answer.

In one of the questions above, you recommend placing the 0.63x reducer/corrector after the Steeltrack focuser. Which adapter would I need to thread the reducer/corrector directly to the Steeltrack focuser?

Is there an adapter that will fit the male threads of Celestron 925 Edge HD on the rear cell and also fit the back of the @"BDS-SC female threads with the 2" adapter removed.
Second question: Is this advisable?
Thank You for any information that you may provide.

I have a BDS-SC/HD which I am using on a Meade LX-85 6" ACF with a Pentax KP camera attached via a T2 adapter. It works very well, thank you.

My question is, will your UHC-S / L-Booster-Filter 2" fit internally in the BDS-SC/HD? If not, do you have another method to use the UHC-S filter with the setup mentioned above?

Can the Baader Diamond Steeltrack® (BDS-SC) Focuser for Schmidt–Cassegrains be used with Maksutov–Cassegrains (specifically Orion Optics (UK)'s OMC200 (https://www.orionoptics.co.uk/OMC/omc200maksutovca.html)? If so, I'll order the focuser straight away! Many thanks. – Peter Gill

Does the S58 dovetail mean that the steeltrack effectively has a rotator built in? I mean, if I use an S58 dovetail to M48 adapter for example to thread into my imaging train, I could then clamp it down onto the steeltrack in any chosen orientation of the camera?

Do you know if we can use the BDS-SC with the Celestron Edge HD focal reducer for Edge HD 8"?

Can I confirm that the focuser can be easily rotated to frame a desired field of view? The "specifications" section indicates that it is rotatable, but I see nothing in the instruction manual to indicate how this is achieved.

We do not have the technical data of all telescopes, so you should have to check the manual of your telescope or contact the manufacturer to be sure. However, the BDS-SC comes with adapters to 2" UNC (SC-thread) and 3,3".

The Sky-Watcher 180 *should* be equipped with a standard SC-thread (2), so you should be able to attach the BDS-SC without any problems - if the description I have found onlie (still) applies to your specific model; technical data can change over the years.

The Mak127 seems to have only a T-2-thread (and a clear aperture of 1,25"), so a 2"-focuser may be a bit over-sized. But you should be able to attach the focuser with the Baader Expansion Ring 2"a/T-2i with 1mm optical path length (T-2 part #28) #2958242. Please check the manual und Downloads for the dimensions the the steeltrack, to see if you get problems with the focussing knob of your telescope.

You can still use the main mirror focuser of your telescope when the SteelTrack is installed.

Application example of BDS-SC Diamond Steeltrack®

General Specifications for all Baader Diamond Steeltrack^® (BDS) focusers:

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 utilizes 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 Diamond Steeldrive temperature-compensating motor drive system
Detachable drive block assembly is reversible for right hand or left hand fine-focus operation and for attaching the Diamond Steeldrive motor block
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

Multiple Adapters available for shortest possible connection to most cameras / eyepieces

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

BDS-SC: all views

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
