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 have a particularly high load bearing capacity can support up to 8kg of accessories.
So attach all your accessories, whether light or heavy with impunity - you don't need to don't worry. You can simply get on with enjoying the night sky.
Fixing focus position for astrophotography
A lock-screw is provided for locking the focus in place for astro-photography. The focusing mechanism is now locked out, meaning you cannot accidentally change the focusing. And, once again, this focuser has the edge over the traditional Crayford design - the screw only locks the focusing mechanism, NOT the inner tube. The focuser hence remains centred as the inner tube is not put under any pressure.
Suitable for a wide range of telescopes
The base plate of the focuser does not have a fixed radius fitting. There is a good reason for this, namely that it allows you to attach the focuser to a wider range of Newtonians. It is suitable for telescopes with an aperture of 200mm upwards.
Tune your telescope, convert it and improve it with the new Tiger Omegon focuser.
The advantages in a nutshell:
- very low-profile design : eliminating many focusing problems
- built-in extension tube : allows length to be adjusted between 50mm and 100mm
- linear Crayford ball bearing focuser, additional rack-and-pinion for firmer hold
- 1:11 reduction ratio - easier focusing for astro-photography
- load-bearing capacity up to 8kg
- compression ring clamping for 1.25" and 2" accessories - providing optimal protection
- drill hole spacing : approx. 55mm left-right and 90mm up-down
- overall dimensions of base plate: 90x115mm
