Moonlite's Ultra light/small foot print CR line of crayford focusers feature extream smooth focus action. All aluminum to bearing riding surfaces are polished to a near mirror surface then anodized hard. This gives the focuser a very smooth buttery feel. Add the 8 to 1 ratio planatery reduction system for dual rate action. The CR2 dual rate uses an state of the art all bearing drive planetary reduction system. No backlash and very smooth action is gained by such systems.
Focusers start at $165 and we offer curve adapters to retrofit 7" to 19" round OTAs. Need more focuser height, just add our optional 1/2" and 1" spacers to get the perfect fit. Optional draw tube lenghts are availible as well. See URL above to order on line.
