Omegon Alpha Crayford Focuser 2 inch Newton: the affordable step to smooth focusing<\/strong><\/h2>\n\n\n\n

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.<\/p>\n\n\n\n

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.<\/p>\n\n\n\n

Ample focusing travel of 59 mm<\/h4>\n\n\n\n

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.<\/p>\n\n\n\n

To bend friction to one's will<\/h4>\n\n\n\n

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.<\/p>\n\n\n\n

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.<\/p>\n\n\n\n

Where this focuser ends<\/h4>\n\n\n\n

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.<\/p>\n\n\n\n

Featured accessories<\/h3>\n\n\n\n

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.<\/p>\n\n\n\n

For whom yes and for whom no<\/h3>\n\n\n\n
