Chapter. 4 How to Observe

4.1Land Objects

If you want to observe land objects, such as a mountain top or a bird, you should use “Land” mode. Simply point the telescope to your target and look through the eye piece. For certain models, such as Newtonian, the image you see in the eye piece is up-side down.

If you don’t want to turn on power and use hand controller, then you need to loosen the telescope’s tripod base lock knob and Altitude lock so that the telescope can move freely in both directions. Next, use the viewfinder to locate your target. Center the target in your eyepiece and tighten the base and Altitude locks. Then adjust focus.

You can also use the hand controller to observe land objects. Turn on the power and from the main menu choose “Land Objects”. If you already have land marks saved in your system and you want to go to one of those land marks (this is assuming that the tripod is not moved since you recorded those land marks), select “GoTo Land Mark” and pick the land mark you want to observe. If you want to record new land marks, select “Record New Land Mark”, on the next screen, use “SPEED” button to choose an appropriate speed, then use arrow keys to move your telescope to your target. When the target is centered, press “ENTER”, then give it a name(with “UP” and “DOWN” arrows you can input alphabets, with “LEFT” and “RIGHT” to move the cursor). Push “ENTER” to confirm you input. Next time, you can go to this land mark by selecting its name in the list under “GoTo Land Mark” menu.

If you use “Land” mode to observe celestial objects in the night sky, you will notice that stars drift away slowly from your eyepiece field, and you have to keep adjusting your telescope to re-center your target. This drift is caused by the rotation of the Earth. This drift can be countered by using the automatic tracking feature of GoToNovaTM.

4.2Using Arrow Keys

On our GoToNovaTM controllers, there are four arrow keys. You can use these keys to adjust and fine tune your telescope. To use this function, make sure you tighten both the Altitude and base locks. Then turn on the power.

With the “User position” screen, press ENTER button to switch between “Land” and “Cele” mode (upper right corner). Use SPEED button to adjust the speed (lower right corner). Use higher speed for initial adjustment. Use lower speed for fine tuning.

Center your target in your eye piece then adjust the focus.
