iOptron IEQ45TM Turn Off the Mount, Initial Star Alignment, Go to the Moon and Other Stars

convert them into d:m:s format by multiplying the decimal numbers by 60. For example, N47.53 can be changed to N47º31'48”: 47.53º = 47º +0.53º, 0.53º=0.53x60'=31.8', 0.8'=0.8x60"=48". Therefore, 47.53º=47º31'48" or 47d31m48s.

N/S Hemisphere Selection

If the polar axis is aligned to North Celestial Pole, then set the mount to Northern Hemisphere. If the polar axis is pointing to South Celestial Pole, set the mount to Southern Hemisphere. Press ◄ or ► key to move the cursor and using ▲ or ▼ key to toggle between “Northern Hemisphere” and “Southern Hemisphere”.

Select Northern Hemisphere if you are located in US and press ENTER to go back to the main menu.

The time and site information will be stored inside the HC memory chip. If you are not traveling to another observation site, they do not need to be changed.

4.3.2. Initial Star Alignment

A simple star alignment/synchronization can be performed to improve the GOTO accuracy.

To perform “One Star Align,” press MENU button, scroll down to “Align”, select “One Star Align” and press ENTER. The screen will display a list of bright objects for you to select from. Select an object using ▲ or ▼ key. Then press ENTER. After the mount slews to the target, use the arrow keys to center it in your eyepiece. Then press ENTER. (More align details in 5.6)

An alternate way is to perform “Sync to Target.” Press the MENU button, select “Select and Slew” and press ENTER. Browse over the catalogs and select an object, such as “Stars” Æ“Named stars” Æ140 (Polaris), and press ENTER. After the mount slews to Polaris, press the MENU button, scroll down to “Sync. To Target”, follow the on-screen instruction to center Polaris and press ENTER. You may need to use the number keys to change the slewing speed to make the centering procedure easier.

4.3.3. Go to the Moon and Other Stars

After performing these set-ups the mount is ready to GOTO and track objects. One of the most common objects is the Moon.

To slew to the Moon press the MENU button. Select “Select and Slew” by pressing the ENTER button. Select “Solar System”, and use the ▲ or ▼ buttons to select Moon. Press ENTER. The telescope will automatically slew to the Moon and lock on it. It will automatically begin to track once it locks on. If the Moon is not centered in your eyepiece, use the arrow keys to center the Moon. Or for better performance use “Sync to Target.”

You may also select other bright celestial objects to start with, such as Jupiter or Saturn.

4.3.4. Star Identifying Function

The 8407 hand controller has a star identifying function. After Set Up Time and Site, slew the telescope to an bright star, manually or using GOTO. Press ? (Help) button to identify the star name telescope is pointing to, as well as nearby bright stars if there are any.

4.4. Turn Off the Mount

When you have finished your observation, just simply turn the mount power off and disassemble the mount and tripod. If the mount is set up on a pier or inside an observatory, it is recommended that you return the mount to Zero Position, or Park Position before powering down. This will ensure that there is no need for you to perform the initial setup again when you power up the mount subsequently, if the mount is
