For other parts of the world, time zone information can be found online such as http://www.timeanddate.com/worldclock/.

DO NOT COUNT DAYLIGHT SAVING TIME.

If your mount is equipped with a GPS receiver only Daylight Time Saving and Time Zone settings are needed. However, the local time and site info can still be manually entered (in case the GPS signal is too weak from clouds or buildings). It is always recommended to get the GPS coordinates before traveling to a new observation site.

4.2.2. Using your telescope

Selecting an Eyepiece:

1.Always begin viewing with the lowest power eyepiece. (Note: a 25 mm focal length eyepiece has a lower power than a

10mm one.) A formula can be used to determine the power of each eyepiece: Telescope focal length divided by eyepiece focal length equals magnification. Ex. 400mm ÷ 25mm = 16X (magnification)

2.Included with this telescope is a 45° Erecting Diagonal Prism. The Erecting Diagonal Prism is used to erect the image you will see. Astronomical telescopes are designed in such a way that the image you see may be UPSIDE DOWN and REVERSED. This is acceptable for viewing celestial bodies. However, it will feel strange when observing a land object or a bird.

Focusing Telescope:

1.After selecting the desired eyepiece aim the telescope tube at a land-based target at least 200 yards away (e.g. A telephone pole or building). Fully extend focusing tube by turning the focus knob.

2.While looking through selected eyepiece, slowly retract focusing tube by turning focusing knob until object comes into focus.

4.2.3. Go to the Moon

After performing these setups, the mount is ready to GOTO and track objects. The most common object will be Moon.

Press MENU button, select “Select and Slew” by press ENTER button. Select “Planets, Sun, Moon”, and using ▲ or ▼ button to select Moon. Press ENTER. The telescope will automatically slew to the Moon and lock on. Press BACK key to stop GOTO. It will automatically begin to track once it locks on to it. Use the arrow keys to center the Moon in your eyepiece, if it is not centered. Press ENTER key to stop the tracking.

4.2.4. Initial Star Alignment

A simple alignment/synchronization can be performed to improve the GOTO and tracking accuracy. To do so, press MENU button, scroll down to “Align”, select “Solarsys Align” and press ENTER. The screen will list Moon, Sun and other planets for you to select from. Select an object using ▲ or ▼ key. Then press ENTER. The mount will slew to the object. Use ◄ ► ▲ or ▼ key to center the object in your eyepiece. Press SPEED button to change the slew speed if needed. Then press ENTER to complete the alignment. Or press the BACK key to cancel the process.

An alternate way is performing “Sync to Target”. To do so, press MENU button, select “Select and Slew” and press ENTER. Then select a known sky object, such as Moon from “Planets, Sun, Moon” menu and press ENTER. The mount will slew to the Moon. When the mount stopped slewing, the Moon could be just inside your eyepiece or way off. Press MENU button and scroll down the menu to “Sync to Target” and press ENTER. Follow the instruction, use ◄
