I have a 2 inch Baader Diamond Steeltrack RT. Can you please confirm the function of the tension brake screw? When this screw is loosened, both the coarse and fine focus knobs can be turned. However when I tighten this screw, the coarse focus knob locks, but the fine focus knob can still be turned and the drawtube and the fine focus knob move as normal. Also when I tighten this screw, focus shifts. Is this correct behaviour, or should tightening this screw lock both knobs and the drawtube. This is not clear in the manual. Thanks.

Is there an 2" BDS-RT Baader Diamond Steeltrack Focuser Adapter for Explore Scientific ED APO with a 54mm 0,75 outer thread? (I have a clicklock 54i that is the fitting Im looking for also for the focus adapter). If not, I’d like to put that up on the wishlist.

I would like to replace the factory fouser on my Sky-Watcher Evostar ProED 80 mm f/7.5 ED APO refractor telescope with your Diamond Steel focuser, but can't find the proper adapter. The factory focuser inserts into the optical tube and is secured with three screws. The screws pass through holes in the optical tube and then thread into the factory focuser. The focuser insertion depth into the optical tube 15mm and the inside diameter of the optical tube is 96,66mm.
Please advise

Can you please advise on the necessary adapter to use in order to connect my Baader diamond steeltrack focuser to my TS 102 doublet APO refractor (TSAPO102F7) - https://www.teleskop-express.de/shop/product_info.php/info/p9868_TS-Optics-Doublet-SD-Apo-102-mm-f-7---FPL53---Lanthan-Objective.html

I have an old Vixen FL102S refractor that I'd love to fit with a Steeltrack focuser. The original focuser fits the optical tube internally and is held in place with 3 screws (around M4 size holes), evenly spaced, 120 degrees apart. The focuser flange outside diameter measures 111.7mm and is a snug fit for the optical tube, which I'm guessing has an internal diameter of 112mm. Do you have an adapter for the Steeltrack that might fit this telescope? Thanks

Reading the manual of the focuser I found that the one for newtonian has an auxiliary m55x0.75 thread cut into the focuser tube.
Can you confirm that? I would need to turn that m55 (female I guess?) to m54 (female). That would be possible?

I have Baader Steeltrack focusers on all my telescopes with the steeldrive motor and would like to fit the 2" Baader Steeltrack-RT to my Skywatcher Esprit 100ed Pro which currently has the stock 3" rack and pinion focuser, which has an M117x1mm thread on the telescope side. Is there a connection you do to allow this or are you likely to do a 3" version of the Steeltrack-RT i the future that would fit.

I would like to use this focuser on a Sky-Watcher Equinox 80ED. I realize this question may have been asked before however, I have additional information. The OTA to which the focuser needs to fit ends with an M84x1 male thread. Do you have an appropriate adapter or can one be custom built? I can send detailed photographs if necessary...

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?

I have a Scopos TL 805 and I would like to change my eyepiece because I have tilt.
I would like to have a clarification concerning the fixing of the BDS-RT (# 2957210).
Indeed, I have contradictory information. In the specifications, I see that the fixing is possible in 88mm dovetail but on this site:
https://agenaastro.com/baader-2-diamond-steeltrack-refractor-focuser-2957210.html
72mm dovetail receiver permits 360-degree rotation of focuser with single-screw locking.
He's talking about a 72mm dovetail.
Can you clarify this point or offer me a fixing solution?
cordially

Do you manufacture a Steeltrack to fit onto a flat plate of larger telescopes? I need one to fit a 20" RC telescope that has a machined flat back-plate that fits flush onto the telescope and is then drilled to accommodate different equipment. Ideally we would like a Steeltrack attached to a flat plate with mounting holes that we can then attach to the telescope back-plate by four screws.

Details
Application example of BDS-SC Diamond Steeltrack
The BDS-RT allows mounting of a finder base and holder (example: MQR-III #2457020)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
Mounting of BDS-Adapters on the example of BDS-NT Diamond SteeltrackClamping 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-RT: all views
Imaging / eyepiece projection on the example of BDS-RT Diamond SteeltrackFocusing 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
