4 1. ZEQ25GT Overview Welcome to a new type of EQ mount! The iOptron “Z” des ign mount puts the payload weight at the center of gravity allowing for greater natural stability. Thi s also means the mount is extremely light compared to its payload—a nice benefit when setting up at a remote site.
5 2. ZEQ25 Terms 2.1. Parts List 1 There are two shipping boxes for a regular tri pod version. One box contains a ZEQ mount, hand controller, one 10.4 lbs (4.7kg) cou nterweight, counterweight shaft, tripod spreader and accessories. The other box contains a tripod.

10 3. ZEQ25GT Mount 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.
11 WARNING: Please DO NOT rock t he counterweight shaft rigorously. You’ll degrade the performance of the spring loaded gear meshing system, or even damage it. WARNING: The new Gear Sw itch will allow you to have most precise weight balance. This also means the mount or OTA will swing FREELY when the Gear Switch is disengaged.

13 (1) Remove CW Shaft Locking Screw from the CW Mounting Nose. (2) Insert CW shaft into the CW Mounting Nose as indicated in 2nd photo below. (3) Lock it using CW Shaft Locking Screw from the other side of the CW Mounting Nose. Tighten the Front CW Positioning Screw which is located in front of the CW Mounting Nose.
14 Rotate the DEC axis to horizontal position. Adjust the CW position to balance the mount in R.A. axis (Figure 14a) and move the OTA position to balance the mount along DEC axis (Figure 14b).
15 To set up the controller, press MENU button on the hand controller. From the main menu, scroll down and select “ Set Up Controller ” Press ENTER and select “Set Up Time and Site” Press ENTER. A time and site information screen will be displ ayed: Set Local Time The time will be updated automatically when the GPS has picked up a signal.
16 Set Observation Site Coordinate The third and fourth lines display th e longitude and latitude coordinates, respectively. The longitude and latitude coordinates will be automatically updat ed when the GPS picks up satellite signals.
17 If a ZEQ25GT mount equipped with an iOptron’s AccuAligning TM polar scope, you can do a fast and accurate polar axis alignment with iOptron’s Quick Polar Alignment procedure.
18 NOTE: If you are located in southern hemisphere, Sigma Octantis will be chosen for Polar Alignment. For example, on May 20, 2010, 20:00:00 in Sydney , Australia (Lat S33º51’36” and Long E151º12’40”), 600 min ahead of UT, the Sigma Octantis Position is 1hr21.

23 5.1.7. User Objects It can store up to 60 used entered 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.
24 Press ENTER. A R.A. anti-backlash screen will display: To adjust steps move the cursor to each digit and use the number keys to input number directly. Press ENTER – “DEC anti-backlash” will display: Move the cursor to each digit and use the number keys to set the anti-backlash.
25 5.3.9. Upgrade RA & DEC Use this operation to upgrade 8408 hand controller, R.A. and DEC motor controller firmware. Please refer to iOptron online documents for ZEQ25 firmware upgrade details. The password is 9999 . 5.4. Align This function is used for aligning the telescope.
