Baader Planetarium



The Baader Diamond Steeltrack 2" Focuser for SC is a high capacity, high precision micro-geared focuser for use with Schmidt-Cassegrain telescopes. Unlike standard Crayford or rack & pinion drives, the true diamond micro-geared mechanism has zero backlash and zero flexure. It is natively compatible with the Prima Luce Lab Sesto Senso 2 or ZWO EAF electronic focusers. The SC focuser includes both 2" and 3.3" SC adapters.

The Diamond Steeltrack 2" focuser can lift a payload of 6kg in a fully vertical position without slipping or excessive bearing preload (bearing preload can be increased further if necessary). The bearing system utilized unbreakable Instrument-grade roller bearings instead of simpler ball bearings, allowing it to handle high loads with greater rigidity and accuracy. Each bearing is individually adjustable for precise alignment of the mechanical vs optical axis. The ultra-hard subzero coated bearing races are precision milled and much harder than anodized or stainless steel. 

The 1:10 stainless steel fine focusing mechanism includes a detachable drive block assembly for reversible right or left hand operation. The zero-shift locking knob precisely stops any movement without affecting optical axis alignment. The drawtube has an oversized 55mm inner diameter to prevent vignetting, with anti-reflection knife-edge baffles.

The built-in S58 dovetail clamp allows you to connect optional T2, M48, M68 and other threaded adapters for direct connection of accessories and cameras without using the 2" clamp. The 2" hardened bronze eyepiece clamp is included as standard. Optionally available is a 2" Clicklock clamp with integrated S58 dovetail for even more precise securing of accessories. The focus tube includes both M60 x 1 and M55 x 0.75 threads for direct connection of some flatteners/reducers.

Worth the $$$

This is an exceptional piece of precision kit. Added it to my Edge HD8 with the ZWO EAF. Eliminating mirror flop, ease of pin point focusing. Highly recommended.

Awesome upgrade to Edge11

Removed the mirror flop issue with moving the primary mirror when focussing during the night. Now rejecting very few subs. Highly recommended product.

I bought the Baader 2” diamond steeltrack dual speed focused to augment focusing on my 10inch Meade LX200gps SCT. I couldn’t be happier. Easy to mount, easy to adjust, very tight and rigid assembly, no backlash, smooth operation, positive feel when making adjustments. I removed the 2inch adaptor plate and attached it with the 3.3inch thread as the Meade thread is 3.25inch it fits just about perfect tightens up great. My scope is fork mounted when pointed to the zenith i have 20mm clearance with the Meade 2inch Diagonal attached to the focuser. Highly recommended.
