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.
2. CEM60 Terms 2.1. Parts List1 SHIPPING CONTENTS There are two shipping boxes for a CEM60 mount. One box contains an aluminum carrying case with a mount, either CEM60 (#7200) or CEM60-EC (#7201) mount head, a hand controller, a counterweight shaft and accessories, including a counterweight pin and locking screws. The other box is for a 21lbs (9.5kg) counterweight.

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.
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.
the Nylon washer. Put the azimuth locking nuts onto the mounting studs, hand tighten them. Adjust tripod/pier to level the mount. Azimuth adjustment knob Mounting stud Nylon washer Figure 14. Attaching the mount STEP 3. Setting the Latitude This step requires you to know the latitude of your current location. This can be found from your 8407 hand controller after the embedded GPS receives the signal from the satellites.
(2) Insert CW Shaft into the CW Mounting Housing. Make sure the rounded top of the shaft is fully engaged in the slot; (3) Insert the CW Shaft Locking Screw into the TOP hole and thread it onto the CW shaft; (4) Tighten the CW Shaft Position Screw. Low latitude position screw Shaft locking screw Shaft position screw Threads on CW shaft Figure 16.
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.

4. Getting Started In order to experience the full GOTO capability of GOTONOVA® technology it is very important to set up the mount correctly before observation. 4.1. Setting the Mount and Performing Polar Alignment Assemble your CEM60 mount according to Section 3.2. Make sure the mount is leveled. Turn the mount power switch on. When the GPS receiver is connected to satellites, the hand controller LCD will display GPS OK. The mount will have correct time and site information.
4.5. Star Identification Function The 8407 hand controller has a star identification function. After Polar Alignment and Set Time & Site, slew the telescope to a bright star manually or using the GOTO function. Press ? (Help) button to identify the star that the telescope is pointing to, as well as nearby bright stars if there are any. 4.6. Turning Off the Mount When you have finished your observation, just simply turn the mount power off and disassemble the mount and tripod.

From the main menu select “Select and Slew.” Select an object that you would like to observe and press the ENTER key. The Go2Nova® 8407 hand controller has a database of about 358,000 objects. Use the ► or ◄ buttons to move the cursor. Use the number buttons to enter the number, or the ▼ or ▲ buttons to change the individual number. Hold on a button to fast scroll through the list.
5.1.6. Constellations This catalog consists of 88 modern constellations. They are listed alphabetically. A list is attached in Appendix E. 5.1.7. Custom Objects It can store up to 60 user-defined objects, including comets. 5.1.8. Enter R.A. DEC Here you can go to a target by entering its R.A. and DEC numbers. 5.2. Sync to Target This operation will match the telescope's current coordinates to Target Right Ascension and Declination. It can be used to correct GOTO pointing error.
The telescope will now slew back to Star A to repeat the above steps. The iteration can be stopped when it is determined that the alignment error has been minimized. Press BACK button to exit the alignment procedure. NOTE: It is highly recommended to use an eyepiece with illuminated crosshairs for accurate centering. NOTE: The movement of the alignment star in your eyepiece may not be perpendicular but crossed, depends on its location in the sky. 5.3.3.
5.4. Settings 5.4.1. Set Time & Site Refer to STEP 8 in Section 3.2. 5.4.2.
The guide port wiring is shown in Figure 26, which is same as that from Celestron / Starlight Xpress / Orion Mount / Orion Autoguider/ QHY5 autoguider pinout. If you have an autoguider that has a pinout similar to ST-i of SBIG, such as Meade/ Losmandy/ Takahashi/ Vixen, make sure a proper guiding cable is used. Refer to your guiding camera and guiding software for detailed operation. DO NOT plug your ST-4 guiding camera cable into any iOptron port or HBX port.
5.6. PEC Option This function only works for a non-high precision encoder version of CEM60 mount. 5.6.1. PEC Playback You can turn “PEC Playback On” while you do the tracking, especially for long time astrophotography. The default status is “PEC Playback Off when the mount is turned on. 5.6.2. Record PEC All equatorial mounts have a small variation in the worm gears which can be corrected by using Period Error Correction or PEC.
5.8. Edit User Objects Besides various star lists available in the hand controller -- you can add, edit or delete your own user-defined objects, especially newly found comets. You can also add your favorite observation object into the user object list for easy sky surfing. Up to 60 comets and other user objects can be stored. 5.8.1. Enter a New Comet Press “MENU =>Edit User Objects” to set user objects.
Select “Add a New Record”. A screen will display asking to Enter R.A. and DEC: Enter R.A. and DEC R.A.: 00h00m00s DEC: +00d00m00s You may enter the R.A. and DEC coordinates of the star you want to watch, and press ENTER to confirm. A more useful application of this function is to store your favorite viewing objects before heading to the field. When the “Enter R.A. and DEC” screen appears, press the MENU button. It brings up the star catalogs that you can select the star from.
6. Maintenance and Servicing 6.1. Maintenance The CEM60 mount is designed to be maintenance free. Do not overload the mount. Do not drop the mount, this will damage the mount or degrade the GOTO tracking accuracy permanently. Use a wet cloth to clean the mount and hand controller. Do not use solvent.
