Brand new open box - Dobsonian Focuser
The dual-speed Crayford focuser features a focus control with 1:1 and 10:1 speed ratios allowing superbly smooth and precise focusing at all magnifications.
The focuser attaches to the telescope via four holes positioned in each corner of the mounting plate.
The focuser is fully 360 degrees rotatable when fitted to the telescope. The focuser has adjustable tension and stiffness making it ideal for carrying heavy eyepieces and cameras. And allows the focus point to be locked by actually disengaging the focus control knob via a thumb knob. This is a beautifully engineered focuser and it functions every bit as well as it looks
