Omegon Crayford-Focuser 2 inch Newton Dual Speed 1:10: precisely focus with 1:10 fine adjustment<\/strong><\/h2>\n\n\n\n

The standard focus mechanism on a Newton is often the weakest part of the telescope. It is sluggish, has play, and shifts under the weight of a heavy camera. This Omegon Crayford focus mechanism replaces that mechanism with a ball-bearing system that moves smoothly and without play.<\/p>\n\n\n\n

The dual-speed gearing is the difference you notice immediately: with the large button you set the focus coarsely, with the small button ten times more precisely. At high magnification and when shooting astrophotography, that is exactly what you need to hit the focus point exactly.<\/p>\n\n\n\n

Bullet-proof Crayford design<\/h4>\n\n\n\n

A Crayford focus lens works without a cam. The pull tube rests on ball bearings and is driven by a smooth shaft. This eliminates any play and ensures no jerky movement.<\/p>\n\n\n\n

You set the friction yourself. If you use a heavier camera, you can tighten the clamp a little so that nothing falls out.<\/p>\n<\/div>\n<\/div>\n\n\n\n

Fine adjustment of 1:10<\/h4>\n\n\n\n

The reduction of 1:10 means that ten turns of the fine knob are equivalent to a single turn of the coarse knob. Each touch therefore results in a slight displacement.<\/p>\n\n\n\n

The focusing distance is 33 mm. That is more than enough for eyepieces, cameras, and extenders on a Newton.<\/p>\n<\/div>\n<\/div>\n\n\n\n

Connections for visual and photographic work<\/h4>\n\n\n\n

The ocular side accepts both 2-inch and 1.25-inch accessories. On the camera side there is a T2 thread (M42 x 0.75) and an M54 thread, so you can connect a camera directly and without vibrations.<\/p>\n\n\n\n

The telescope connection measures 78 mm. That is the standard screw spacing for many Newton tubes, including the Omegon Advanced series.<\/p>\n<\/div>\n<\/div>\n\n\n\n
