USING THE TELESCOPE
RED DOT VIEWFINDER ALIGNMENT
Look for different features on the Moon. The most obvious features are craters. In fact you can see craters within craters. Some craters have bright lines about them. These are called rays and are the result of material thrown out of the crater when it was struck by a colliding object. The dark areas on the Moon are called maria and are composed of lava from the period when the Moon still had volcanic activity. You can also see mountain ranges and fault lines on the Moon
SOME OBSERVING TIPS
Barlow lens You can also change magnification by using a Barlow. Remove the eyepiece from the diagonal mirror and slide in the Barlow. And then place the eyepiece into the Barlow. Tighten the thumbscrews to secure the Barlow lens and the eyepiece in place. A Barlow lens doubles the power of your telescope
