Omegon Alpha Crayford Focuser 2-inch for Newton

Omegon Alpha Crayford Focuser 2 inch Newton: the affordable step to smooth focusing

Anyone who owns an entry-level telescope knows the problem: the included focuser is jerky and you keep overshooting the focus point. The Alpha Crayford is the cheapest way to solve that without replacing the rest of the telescope.

The Crayford mechanism works without a rack and pinion, so the movement is smooth and free of backlash. You find the focus point faster and hold it.

Ample focusing travel of 59 mm

With 59 mm of drawtube travel, you have plenty of room to achieve focus with eyepieces of varying heights. A Barlow lens or star diagonal also fits within the range without the need for extension tubes.

To bend friction to one's will

With a set screw, you determine the tension of the focuser. A light setting is nice for light eyepieces, while a heavier setting prevents slipping with a heavier accessory.

The compression ring holds the eyepiece all the way around instead of with a single screw. That prevents tilting and protects the barrel of your eyepiece.

Where this focuser ends

The payload capacity is 1 kg and there is no fine adjustment. For visual work, that is fine. If you want to photograph with a DSLR or astro camera, look at a dual-speed model.

Featured accessories

After installing a new focuser, your Newtonian telescope needs to be re-collimated. A 1.25-inch laser collimator is the fastest solution for this.
