9.Manual Operation of the Mount: Now you can observe astronomical objects using the arrow keys of a Go2NovaTM hand controller. Flip the I/O switch on the telescope mount to turn on the mount. Use ►,◄,▼ or ▲ buttons to point the telescope to the desired object. Use the number keys to change the slewing speed. Then press STOP/0 button to start tracking.
10.Setup Controller: The iEQ30 is equipped with a GPS receiver, which will receive the local time, longitude and latitude information from satellites after the link is established. However, In order to make hand control reflect your correct local time, time zone information and Daylight Saving Time still need to be entered.
Turn on the power. Wait for controller lights on. Press the MENU button. Move the cursor to “Set Up Controller” and press ENTER. Select “Set Up Time and Site” and press ENTER. Enter the date and check if it is Daylight Saving Time using arrow keys and number keys. Enter your time zone (add or subtract 60 minutes per time zone) by entering minutes “behind” UT or “ahead of” UT, such as:
•Boston is 300 minutes “behind” UT
• Los Angeles is 480 minutes “behind” UT | Figure 6 | ||
• | Rome is 60 minutes “ahead” of UT | ||
| |||
• | Sydney is 600 minutes “ahead” of UT |
| |
Move the cursor to the bottom of the screen to select Northern or Southern Hemisphere.
11.Adjust the Mount to Zero Position: The Zero Position is the position where the counterweight shaft points to ground, telescope is at the highest position with its axis parallel to the polar axis and the telescope is pointing to the Celestial Pole. Loosen the DEC and R.A. Clutches to adjust the mount to the Zero Position. Tighten the screws after each adjustment. Power cycle the hand controller.
12.Star Alignment: Star alignment will improve the GOTO accuracy. From the main menu select “Align”. Select “One Star Align” and press ENTER. Make sure your scope is at Zero Position. A list of align stars that are above the horizon is computed based on your local time and location. Select a star and press ENTER. Use arrow buttons to center the star in your eyepiece. Using number key to adjust the slew speed while centering the object. (1 for slowest, 9 for maximum). Press ENTER when finished. You may also choose two star or three star alignment to increase the go to accuracy of the mount.
13.Go to an Object: The mount is now ready to GOTO and tracking targets. Press MENU button, select “Select and Slew” and press ENTER. Select a category (ex. “planets, sun, moon”). Then select an object (ex. “moon”). Then press ENTER. The telescope will automatically slew to the object and lock on. It will automatically begin to track once it locks on to the object.
14.Sync to Target: One can also use this function to center and synchronize the object from Step 12 to improve the local GOTO accuracy. This is more helpful if you are looking for some faint object near a bright star. A Select and Slew has to be performed before “Sync to Target” operation. Press MENU button and select “Sync. To Target.” Press ENTER. Next use the arrow keys to move object until it is centered in your eyepiece. Then press ENTER again on the hand controller. “Sync to Target” is similar to one star alignment.
