With the internal GPS, just choose any 3 bright stars or planets in the sky and the telescope is aligned and oriented. For the intermediate to advanced viewer, the Celestron CPC 800 XLT Goto that can take you to any of more than 40,000 objects.
It's accurate and easy to set up. It has a lot of control capabilities. On my first night I enjoied seeing Saturn, a couple of galxies (faint images but still overwelming just to know that you are looking at one) and the butefull Hercilues cluster (thisone realy suprised me). It's protable but it is not light. Buy. A 12 volt battery source and get a set of good moderate to high power eye pices. Alighned the finder properly and it will help you a lot. It is easy to alighn the scope the sky allign method. Do it carefully (follow all the steps carefully) and it will work like magic when you use the go to control (you may stil need to center the objects in the eye piece). Worth the money.
