Crayford - Extremely low-profile design for perfect focusing
With the Omegon 2 inch Newtonian focuser, you have perfect focusing at your fingertips. The extremely low-profile design eliminates the all-too-common focusing problems.
Rotate the focus ring and you will immediately notice that the inner focusing tube slides satin-smoothly and has no play. The entire focuser has a very elegant black anodised exterior design. The interior has a mat black coating with machined-in grooves which suppress unwanted reflections.
Low-profile focuser design
The incredibly low-profile design - a squat 50mm - now allows you to pull any object into focus. And if your eyepiece or camera has to be moved a little further out? No problem - simply pull out the built-in extension tube to the length required.
Tiger Crayford - The improved Crayford focuser
'Bearing Type' is the name of the new, improved, Crayford design. The Crayford focuser design already had the advantage of a backlash-free focusing. The secret of the Omegon focuser is the use of roller ball bearings: 8 large rollers keep the inner tube firmly in position and allow the tube to slide smoothly into the desired position. An additional rack-and-pinion allows the focuser to 'stay where it's put' - the tube does not slip out of position as easily as with traditional Crayford focusers.
1:11 reduction ratio for sensitive focusing
An additional planetary gear provides 1:11 reduction for the Omegon Bearing Type. Adjustment in the 1/10 millimetre range is provided, making focusing on astronomical objects particularly straightforward as the optimal focus position can always be easily located.
High load capacity of up to 8kg
What do SLR cameras, large CCD cameras, Off-Axis guiders and large 2 inch eyepieces have in common? The answer is that they often quite heavy, especially when used in combination. For this reason, the Omegon Crayford focuser has been designed to
