been waiting for months for a focuser to come up on AM don't have one at all right now as i have sold my JMI. too late as i have paid the seller on AM

. according to moonlites website:
The dual rate Tri-knob option is a 2-speed configuration with a regular knob on one side and a fine and coarse knob on the other. Both coarse knobs are 1.2" OD, and the fine knob is 1" in size. The fine knob uses an oversized 8 to 1 reduction unit featuring a preloaded, all ball bearing planetary reduction design that has no backlash or play. The inline unit can simple be rolled by the slightest touch of your finger to make very fine focus movements plus has an auto brake when focus is stopped. No scope wiggles here and perfect collimation plus an 5 lb weight capacity make this option ideal for typical visual or imaging use. The fine knob is on the right by default, but can be made a lefty if needed. If increased lifting capacity is needed, please consider one of our motor options below. The motor option give the CR focuser a 8 lb lifting capacity rating. $100 option.
ideal for typical visual or imaging use. Are they referring to a Meade DSI or a Toucam? or unless maybe i can drill a hole on the turning knob and put a screw in to hold it? *shurgs*
