Explore Scientific’s dual speed, 2" Air-Spaced Triplet Focuser comes with a 1.25" compression ring eyepiece adapter for added versatility. This adapter or your 2" eyepiece or barreled accessory locks securely into place with three set screws so everything stays put. The heavy-duty focuser has 10:1 micro-focusing knobs as well as a rough focus knob. This 10:1 ratio means that you would have to rotate the micro-focusing knob ten times to get the same focus movement with just one rotation of the larger knob. The focus knobs themselves are large and knurled, so that you can grip them easily, even when your hands are cold or you are wearing gloves.
The focuser also offers tension adjustment that allows you to lock and/or adjust the tension on the drawtube. This is a nice feature that comes in handy when you increase or decrease the weight of eyepieces, cameras or other accessories.
