1. CEM60 Overview ® Welcome to a new type of EQ mount- The iOptron Center-Balanced Equatorial Mount, CEM! Its unique balance design puts the payload at the center of gravity allowing for greater natural stability. This also means the mount is extremely light compared to its payload—a nice benefit when setting up at a remote site. The adjustable counterweight bar prevents the counterweight from getting in the way of the tripod or pier when operating at a low latitude position. Polar align

2.4. CEM60 Gear Switches The CEM gear system utilizes a magnetic force system for optimal gear meshing. Fully turn the Gear Switch clockwise to disengage the worm from the worm wheel. Turn the Gear Switch counterclockwise to engage the worm to worm wheel, as indicated on the mount. The Gear Switch MUST NOT be left in a position that is in between the Engaged and Disengaged positions. Setting the Gear Switch in between states may damage the worm or worm wheel. WARNING: Never disengage or a

3. CEM60Mount Assembly 3.1. Introduction You have just purchased a telescope mount that is capable of taking you to a new level of astronomy. No matter which telescope or optical tube assembly (OTA) you select to install on the mount, the overall performance will be greatly enhanced. In order for you to get the optimum performance from the mount and OTA combination, you must assemble and set up the mount correctly. The following fundamentals of telescope mounts are included to help you u

WARNING: DO NOT rock the counterweight shaft rigorously. Worm system damage due to improperly gear mesh/slippage will not be covered by warranty. WARNING: The new Gear Switch will allow you to achieve the most precise weight balance. This also means the mount or OTA will swing FREELY when the Gear Switch is disengaged. Always hold the OTA or mount when releasing Gear Switch or adjusting gear tension. STEP 1. Removing the Mount from the Carrying Case The mount is shipped with both R.A. G

STEP 6.Balancing the Payload After attaching the scope and accessories, the mount head assembly must be balanced in both the R.A. and DEC axes to ensure minimum stress on the mount driving mechanism. WARNING: The telescope may swing freely when the R.A. or DEC Gear Switch is disengaged. Always hold on to the telescope assembly before releasing the Gear Switches to prevent it from swinging, which can cause personal injury and/or equipment damage. The CEM gear system utilizes a magnetic f
