User manual for the JMI Telescopes EV-3C Focuser for Cassegrain Telescope EV3C
The user manual for the JMI Telescopes EV-3C Focuser for Cassegrain Telescope EV3C provides
necessary instructions for the proper use of the product Optics - Telescopes - Focusers.
The JMI EV-3C is a fine rack-and-pinion focuser designed to work with Cassegrain Telescopes from 6" to 16" diameter. It is a 2" black-anodized aluminum focuser equipped with knurled knobs, standard brass ring and reducer to accept 1.25" eyepieces. The EV-3C can support up to 4 pounds. It features manual control for focusing, which is over 1 1/2 times finer than any other products of its class. This version comes with the SCT threaded output adapter to allow use of standard (SCT and Mak-Cas) equipment. The hand unit has an electronic brake to stop the motor during usage. Some older Meade LX200 telescopes do not supply enough power to run the motor on the low setting.
