Omegon Crayford 2″ focuser for Newtonian telescopes
If you want to get the most out of your Newtonian telescope, start with the basics - the focuser. The stock focuser that comes with a telescope is often the weakest link in the entire system. The Omegon Crayford 2″ focuser for Newtonian telescopes from the Advanced series is precisely the component that allows you to focus smoothly, reliably, and without any unwanted eyepiece movement. Whether you are observing planets at high magnification or photographing deep-sky objects, precise focusing is the key to sharp results.
Crayford design - smooth and backlash-free movement
The focuser operates on the Crayford principle - instead of a rack and pinion, it uses friction rollers that provide perfectly smooth drawtube movement with no play or jerking. This approach is popular among astronomers precisely because it eliminates mechanical vibrations during focusing, which would otherwise blur the image or disturb a frame during astrophotography.

Designed for both visual observers and astrophotographers
Generous drawtube travel and wide light path
The drawtube travel of 35 mm is more than sufficient for the vast majority of eyepieces and cameras. The light path diameter of 50.5 mm ensures no restriction of the light cone even with fast Newtonian telescopes with a low focal ratio.
Dual eyepiece barrel compatibility
The eyepiece-side connection supports both the standard 1.25″ and the full 2″ format, so you can use wide-field eyepiece systems or 2″ filters without any issues.
2.5 kg load capacity - ready for heavy equipment
The 2.5 kg load capacity at zenith is a parameter that astrophotographers in particular will appreciate. The focuser can comfortably support heavier eyepiece systems such as Nagler or Ethos, as well as compact planetary or deep-sky cameras combined with a collimator or filter wheel.
Ring clamp for secure eyepiece retention
The focuser includes a ring clamp that holds eyepieces firmly in place and prevents unwanted slippage - another major advantage during astrophotography, when the focus position must not shift during an exposure.
Compact yet robust construction
With a total weight of 575 g and a housing length of 85 mm, the Omegon Crayford 2″ is a compact yet solid component without unnecessary added bulk. It attaches to the telescope via a standard 78 mm mounting hole, making installation straightforward on most compatible Newtonian reflectors.
Who is this focuser for?
The Omegon Crayford 2″ is an ideal choice for:
- Visual observers who want smooth and precise focusing with 2″ eyepieces
- Beginner and advanced astrophotographers working with Newtonian telescopes
- Users upgrading from a stock focuser to improve their overall optical system performance
If you are considering adding a motorized focuser in the future, please note that this model does not include a motor drive as standard. For automated focusing, you would need to look at a different model within the Omegon range.
