Omegon Pro 2″ Newton Crayford 1:10 focuser
If you have ever experienced the frustration of being unable to achieve a sharp image simply because your existing focuser behaved unpredictably or failed to hold a heavier eyepiece in place, then the Omegon Pro 2″ Crayford focuser with 1:10 dual-speed mechanism is made precisely for you. Designed for Newtonian telescopes, it combines a robust construction with smooth two-speed mechanics that allow precise focusing even at high magnifications or when using heavy eyepiece combinations.
Precise focusing with 1:10 dual-speed mechanism
At the heart of this focuser is a gear mechanism with a 1:10 ratio - a key feature for demanding observers and astronomers. In practice, one full turn of the fine-adjustment knob moves the drawtube only a fraction of what the main knob would produce. This makes it possible to achieve critical focus when using short focal length planetary eyepieces or when shooting astrophotos - situations where millimeter-level precision determines the final result.
The drawtube travel is 50 mm, which provides a sufficient range for comfortable focusing with various eyepiece combinations, including when using a coma corrector or a Barlow lens.
High load capacity and reliable clamping
One of the most important qualities of a good focuser is its ability to hold the eyepiece in the exact position without slipping. The Omegon Pro Crayford 2″ handles a load of up to 2.5 kg at zenith, a specification that will be especially appreciated by astrophotographers working with heavy CCD or CMOS cameras, filter wheels, or binocular viewers.
The ring clamp clamping mechanism ensures even grip and minimizes the risk of the eyepiece rotating or drooping under load. The total weight of the focuser is 802 g, which reflects its solid all-metal construction.
Compatibility and design
The focuser features a standard 78 mm telescope-side connection diameter, matching common Newtonian optical tubes. On the eyepiece side, it supports both the popular 2″ format and standard 1.25″ accessories - the adapter is included, so you do not need to limit your choice of eyepieces.

The black finish is both aesthetically fitting and functionally useful - it minimizes unwanted internal reflections inside the tube. The focuser is entirely manual, with no motor or rotation mechanism included. For visual observing as well as basic astrophotography, this is a perfectly sufficient solution that adds no electronic complexity.
An upgrade for astronomers who demand quality mechanics
The Omegon Pro range is designed for astronomers who refuse to compromise on mechanical quality. Omegon as a brand has long been built on the principle that quality accessories extend the useful life of your entire optical system and significantly improve the observing experience.
The Crayford Pro 2″ focuser is not just a replacement part - it is an upgrade that transforms an average Newtonian into an instrument that is a genuine pleasure to use, whether you are at the eyepiece visually observing or processing astrophotos at your monitor. For everyone who takes astronomy seriously and wants the confidence that the mechanics will not fail at the moment when perfect seeing finally arrives, Omegon Pro is the clear choice.
