TIP:

A GPS module makes life a lot easier. It automatically sets the time and location for you.

TIP:

The controller automatically skips those stars below the horizon of your current time and location.

0.2 Getting Started

For most beginner users who may not need a lot of astronomical detail this chapter gives just enough information to set up the controller. After the easy-to-follow setup you will be ready to point your telescope to wherever you want in the night sky.

After assembling the telescope [Refer to our Assembling Chart] turn on the power button located on the mount. You will see the iOptron logo displayed for a few seconds. Then you will see the zero position screen. By default, it works in Alt-Az mode:

When the power is turned on you will see “G_ON” (GPS turned on) in the upper right corner of the screen. In about a minute, after the internal GPS communicate with the satellites, you will see “G_OK” on the screen. Both time and location are automatically set. If there is no GPS module connected you will need to set up time and location manually. Press MENU button. Then you will see this screen:

TIP:

Spend some time familiarize yourself with those bright stars in the night sky

www.iOptron.com

Press ENTER to select “Set up local time”, and you will see this screen:

Set Local Time:

2007-06-18 14.49.18

Daylight Time saving√

Use the LEFT and RIGHT keys to move the cursor, and use the number keys to adjust the numbers. When the correct local time has been entered, press ENTER. Then you will see this screen:

Set up site Info: Longi: W071d27m47s Latit: N42d15m40s 300 Min. behind UT

Again, use the LEFT and RIGHT keys to move the cursor, and use the number keys to adjust the values. You need the longitude and latitude values of your location. These values can be obtained from the internet (for example: http://www.latlong.com/) or your GPS device. The last line is the time zone information. Check your time zone and enter properly. For example, Boston lags Universal Time (UT) by 5 hours, which means 300 Minutes behind UT. Use the UP or DOWN key to switch between “ahead of” and “behind”.

Press MENU button, then you will see this screen:

Z 221°20.0′

Center the target then press “ENTER” 2X

Use “UP” and “DOWN” arrow buttons to select a star and press ENTER. Use SPEED button to select a speed, and use arrow buttons to center the star in your telescope. Press ENTER when finished. Now your GoToNovaTM is ready to direct you to any location in the night sky (provided that the object is in the database and above the horizon). Simply choose any object in the menu and press ENTER. Although not required, we strongly suggest that you double check your initial alignment with additional bright objects in the night sky, For example, in the menu, select “Venus” (if it is indeed in the sky) and press ENTER. When the motor stops check to see if

Venus is in the center of your eye piece. If your previous steps were correct, it should be.

You may need to make some minor adjustments to center the object. Otherwise, use “two-star align”.

What’s Next?

Most beginner users are now ready to explore the night sky without needing to refer to the manual any further. The function you will need most is “Select and slew” in the main menu. From there you can select and explore planets, stars, galaxies, nebulae, comets, asteroids, etc.-- virtually all of the most common celestial objects are included.

If there is no GPS connected refer to 0.2 Getting Started on how to manually set up time and location.

The mount can also work in equatorial mode. Tilt the mount to the appropriate angle and point it to the polar star. Go to “Set up GotoNova”, select “Set Mount Type”, and select Equatorial mode.

1.2 Align

1.2.1One-Star Align

From the main menu, select “Align”. The system provides for “one-star align” and “two-star align”.

Select “one-star align”. You will see this screen:

press “ENTER” 2X

Use “UP” and “DOWN” arrow buttons to select a star and press ENTER. Use SPEED button to select a speed, and use arrow buttons to center the star in your telescope. Press ENTER when finished.

1.2.2Two-Star Align

If your mount is not horizontal one-star align is usually not accurate enough. You will need to do two-star align. Select “Two-star align” from the previous menu. Select one bright star from the menu. Use the arrow buttons to center it in the telescope and press ENTER. Select a second bright star and use the arrow keys to center the second star. Press ENTER. Two-star align is finished.
