Explore Scientific AR Series Focuser - 2" - FOCDAR-00

The Explore Scientific Focuser is available in several different models, and while there are some differences, especially on the "telescope end", there are a lot of similarities as well. All Explore focusers are 2", and come with 1.25" compression ring eyepiece adapters. The adapter, or your 2" eyepiece or barreled accessory, locks securely into place with three set screws so everything stays put.

All of the Explore Scientific Focuser have 10:1 micro-focusing knobs as well as a rough focus knob. 10:1 means that you would have to rotate the microfocusing knob ten times to get the same focus movement with just one turn, or 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. A tension adjustment feature is included on all focusers. The ability to lock and/or adjust the tension on the drawtube is a nice characteristic, and you''ll appreciate it when you increase or decrease the weight of eyepieces, cameras, or other accessories.

If you are buying a replacement Explore Scientific Focuser for your Explore Scientific telescope, please refer to the product numbers and descriptions to make your choice. If you are thinking about buying one of these focusers for a different telescope, measure carefully, and unless you know for sure, give Customer Service a call and double-check to make sure your telescope and the focuser will match up nicely.
