More product information
This JMI Motofocus electric focuser is designed for use with all Meade Cassegrain telescopes (except ETX models and 16" scopes) that have a round focusing knob 0.865" in diameter. See the feature image to confirm this is the shape of the focusing knob on your scope.

It appears that ALL Meade 14" SCTs have a ROUND knob with a LARGER diameter than the smaller SCTs and so require the #2405H electric focuser.  To verify this with your 14" Meade SCT, measure the knob diameter.  It should be 0.975" and would require the #2405H Motofocus.  However, if the diameter is only 0.865", then order this #2405 focuser.

The focuser consists of a plastic replacement focus knob, a plastic focus collar, a variable speed DC motor, a hand control, and all necessary mounting hardware.

The telescope focus knob is removed using the supplied Allen wrench and the supplied JMI plastic focus knob is installed in its place. The focus collar attaches in minutes to the rear cell of the telescope, around the new focus knob, using a supplied Allen wrench. The push-on DC motor slips over the focus collar. The motor has electromagnetic braking for very precise focus control. A rubber O-ring inside the motor provides a secure grip on the focus knob centered within the focus collar. The O-ring gripping the focus knob acts as a slip clutch to prevent damage if the normal telescope focuser travel is exceeded. The motor is held in place on the focus collar by a nylon thumbscrew in the motor housing. The motor can be easily removed for traveling or storage. The telescope focuser can still be used manually if the electric focus motor is removed from the focus collar, which can be done in only 10-15 seconds.

The cable permanently attached to the motor plugs into the supplied hand control. The hand control holds a 9-volt battery (supplied) that will power the focuser for 6 to 8 months of normal use. Pushbuttons control the direction of focuser travel, while a slide switch changes the focus speed from standard to ultra-fine. In addition, if a major focus change is needed, holding down either directional focus pushbutton for more than two seconds will switch the motor into a very high speed mode for gross focus changes until the push button is released. The motor reverts to its fine-focusing speed the next time the pushbutton is depressed.
