For greater sharpness
Simple rack-and-pinion focusers often wobble, making focusing a test of patience. This Crayford focuser puts an end to that. What can it do? Because it runs on ball bearings, you can focus on the object smoothly and without play – even at very high magnifications. In addition, you can use the locking screw to fix the focus at any time if you want to ensure it does not shift from its position. You can now find the perfect focus immediately and right from the start. For customised use with your specific telescope tube, please contact our customer service.
