    STOP/0 Key: Stop the mount during GOTO. Also toggling between start and stop tracking.  HBX (Handbox) port: connect the HC to the CEM60 mount using a 6-wire RJ11 cable.  Serial port: connect the HC to a Computer via a RS232 to 4-wire RJ-9 cable. The pin out of the serial port is shown in Figure 9.

  • Page 13 There are two sets of mounting studs and azimuth locking nuts. Thread the two studs onto an iOptron tripod/or pier (if you are using one). Use the pair of mounting holes that are closest to the edge and thread the studs using the shorter thread side. Use the lever to tighten the mounting studs. Make sure that two studs are aligned eastern-western side by turning the tripod or pier.

Setting Hand Controller The CEM60 mount is equipped with a GPS receiver, which will receive the time, longitude and latitude information from satellites after the link is established. However, there are still some parameters which need to be entered to reflect your location, such as time zone info and daylight saving time.

  • Page 18 STEP 9. Performing Polar Alignment One of the CEM60’s unique features is that the polar scope can be accessed at anytime. It will not be blocked by DEC axle as in a German equatorial mount. This makes it possible to adjust the polar alignment during the tracking.
  • Page 19 Quick Polar Alignment (1) Level the CEM60 mount and set it at Zero Position. Make sure the telescope is parallel to the pole axis (R.A. axis) of the mount. If a finder scope is used, adjust it to be parallel to the telescope optical axis.
  • Page 20 Figure 24. Polaris Position shown on HC (a) and where to put on polar scope dial (b) NOTE: If you are located in the southern hemisphere, Sigma Octantis will be chosen for Polar Alignment. For example, on May 20, 2010, 20:00:00 in Sydney, Australia (LatS33º51’36” and Long E151º12’40”), 600 min ahead of UT, the Sigma Octantis Position is 1hr21.8m and 64.4m.
