Installation Instructions

WARNING:
Never disengage Gear Switches without holding the mount firmly! Personal injury and/or equipment damage may happen.

1. Remove mount head from package: The RA axle is locked by an Allen wrench (blue circle) for a mount with iPolar or without polar scope. Make sure it is inserted all the way in. Check the R.A. and DEC Gear Switches and make sure they are at the unlock position before removing it from the box.
   If the mount has an AccuAlignTM optical polar scope, the Allen wrench will NOT be inserted here.

2. Set up tripod: The mount has a 102mm base. Thread the Alignment Peg onto the tripod head, on top of a tripod leg, or between two legs depending on the latitude. Insert the Accessory Tray through the center rod and secure the setup by tightening the Locking Knob from underneath.

3. Attach mount head: Before put the mount onto the tripod, make sure the RA gear switch is at lock position to prevent the mount head free swinging by accident! Retract the 2x Azimuth (Azi) Adjustment Screws from both sides to leave ample space for the alignment peg to be fitted in between the 2x Azi Adjustment Screws. Remove the 2x Azi Locking Screws from the mount base. Secure the mount head by tightening the Azi Locking Screws into the M6 holes on the tripod. After tighten the Azi Locking Screws, store the Allen wrench at the bottom of the mount altitude support.
   Level the mount by adjusting the tripod legs. Use the built-in Bubble Level Indicator or an external leveler for this purpose.

4. Adjust latitude: Loosen the Latitude Locking Lever. Turn Latitude Adj. Knob to adjust the latitude until the arrow points to the current latitude on the Latitude Scale. Tighten the Latitude Locking Lever.
   [TIP: You may lift the handle by pushing the button on this ratchet lever to disengage gear teeth and rotate freely for quick adjustment.]

5. Install counterweight (CW) shaft: Thread the CW shaft into the CW shaft mounting holes. For low latitudes (<10°), a special CW mounting house is needed. (Contact iOptron for more information)

6. Install counterweight: Before putting on CW, make sure the mount is at its zero position, i.e., CW shaft points to the ground. Insert Allen wrench to lock the RA axle and disengage the R.A. Gear Switch to set the R.A. axis free before loading the CW. Remove the CW Safety Cap at the end of CW Shaft. Glide the CW over the shaft with the larger opening facing down.
   Tighten the CW Locking Screw to hold the CW in place. Place the Safety Cap back onto the shaft. Move the CW to the bottom of the shaft and tighten the CW locking Screw.
   [TIP: CEM26 comes with a 10.4 lbs (4.7 kg) CW, which should be sufficient for an 8” scope with total payloads up to about 13 lbs (6kg). Use extra CW or CW Extension Bar to balance higher payloads.]

7. Install telescope: CEM26 has a Vixen dovetail saddle, with center adjusting block. Release the dovetail Saddle Locking Knob and slide the telescope dovetail plate into the saddle. Tighten the Saddle Locking Knob.

8. Balance payload: After attaching the scope and accessories, the mount head assembly must be balanced in both DEC and RA axes to ensure minimum stresses on the mount driving mechanism.
   CAUTION: The telescope may swing freely when the R.A. or DEC Gear Switch is disengaged. Always hold on to the mount and/or telescope assembly before releasing the Gear Switches to prevent it from swinging, which can cause personal injuries and/or equipment damage. Set the mount at Zero Position. Disengage both RA and DEC gear switches and move the mount to a horizontal position to check balance. Return to Zero Position for balance adjustment. Balance the DEC axis by moving the scope with accessories back and forth in the mount saddle or within the scope mounting rings. Balance the assembly in the R.A. axis by moving CW along its shaft. Repeat the process until both DEC and RA axes are balanced.
   CAUTION: The balancing process MUST be done with Gear Switch at the total disengaged position! Otherwise, it might damage the worm system.
   Return the mount to Zero Position after balancing and engaging the gear switches.

9. Install hand controller battery: The hand controller uses a CR2032 button battery to keep the Real Time Clock running. The HC is shipped without a battery installed due to shipping restrictions. Open the HC back cover. With the battery + sign facing up, slide the battery under two small metal hooks on the positive side first. Then push the battery down to make good contact.

10. Connect cables: Use the short RJ11 cable to connect the DEC control unit to the DEC port of the RA/main control unit.
    Connect the Go2Nova® 8409 Hand Controller to the HBX port on the main unit. Plug in a 12V DC power supply to the DC12V IN socket next to the HBX port, not the DC12V OUT next to the GUIDE port.
    Plug the optional GPS module into the iPORT with a coiled cable. When powering on, the GPS ON sign should be displayed at the upper right corner of the hand controller. You may disconnect the GPS module after it picks up satellite signals and displays GPS OK. (It takes about 1 to 2 minutes in normal conditions).

11. Set controller: Press the MENU button; then “Settings” => “Set Time & Site”.
    Enter the current date or wait for the GPS to connect to the satellites. Enter the time zone offset to the UTC; for example:

    • Boston is “UTC -300 minutes”
    • Los Angeles is “UTC -480 minutes”
    • Rome is “UTC +060 minutes”
    • Sydney is “UTC +600 minutes”
      Toggle the Daylight Saving Time (DST) between N(No) and Y(Yes) using the arrow key. Move the cursor to the end of the screen to select the Northern or Southern Hemisphere.
      [TIPS: All time zones in N. America is “UTC -XXX minutes”. Latitude and longitude coordinates can be obtained from GPS-equipped devices (navigator, phone), or from the internet if you are entering them manually. “W/E” = western/eastern hemisphere; “N/S” = northern/southern hemisphere; and “d” = degree; “m” = minute; and “s” = second. Use arrow and number keys to enter location information.]

12. Polar alignment: A CEM26 mount may be equipped with an iPolarTM electronic polar scope or an AccuAlignTM optical polar scope. Please refer to CEM26 User’s Manual for detailed polar alignment procedures.
    iPolar Polar Alignment
    For a CEM26 with an iPolar, refer to iPolar Operation Manual from iOptron’s website to perform the polar alignment, or the steps briefly outlined below:

    • Download and install iPolar Software (first-time use);
    • Connect a mini USB cable between the iPolar and a computer USB port;
    • Click Connect and start polar alignment by following on-screen instructions.
      Quick Polar Alignment
      Fast and accurate polar alignment can be performed for a mount with an AccuAlignTM optical polar scope.
    1. Thread the polar scope LED onto the polar scope. Connect the LED cable between the LED and DC12V OUT socket from the DEC unit.
    2. Use the Hand Controller (MENU => “Align” => “Pole Star Position”) to display the Polaris Position on the LCD screen, as indicated in the left side of the figure below. For example, on June 22, 2014, 20:19:42 in Boston, US (alt N42°30’32” and long W71°08’50”), 300 min behind UT, the Polaris Position is 0h45.8m and 40.4m.
    3. Use the Azimuth and Latitude Adj. Knobs to adjust the mount in both directions and put the Polaris in the location on the Polar Scope Dial (same as indicated on the HC LCD), as shown in the right side of the above figures.
       BrightStar Polar Alignment
       When the pole star is not in sight, refer to the online Instruction Manual for BrightStar Polar Alignment.

13. Manual operation: The mount can now be used to observe astronomical objects with the HC. Use arrow keys (►, ◄, ▼, and ▲) to point the telescope to the desired object. Use the number keys to change the slewing speed. Press the STOP/0 button to start tracking.

14. Set Zero Position: The Set Zero Position command registers the current position as zero position. So before registering, the mount should be physically set at Zero Position either manually or slewed by hand controller. The Zero Position is defined as the telescope being on top of the mount head and pointing to the North Pole, with the CW shaft pointing to the ground. To register, press MENU => Zero Position => Set Zero Position. Press ENTER to confirm.

15. One Star Alignment: Perform One Star Align to correct the Zero Position discrepancy and improve GOTO accuracy. Refer to User’s Manual for more details about improving GOTO accuracy.

16. Go to an object: The mount is now ready for GOTO and tracking targets. Press MENU, select and ENTER Select, and Slew. Select a category (e.g., Solar System), then select an object of interest (e.g., Moon). Press ENTER and the telescope will slew to the object and automatically start tracking.

17. Sync to Target: If the object is not in the center of the eyepiece, use this function to center and synchronize the object to improve local GOTO accuracy. Press MENU and select and ENTER Sync to Target. Follow the on-screen instruction to perform the sync.
    [TIP: After slewing to an object, a list of nearby bright object(s) can be displayed by pressing the? button.]

18. Put the mount back into the package/carrying case: It is recommended to return the mount to Zero Position at the end of the observing session. Lay the mount into the carrying case. Disengage the gear system for transportation. Insert Allen wrench to lock the RA axis.
