Observe the Moon: When you feel comfortable with the finder, the eyepieces, the locks and the adjustment controls, you will be ready to try out the telescope at night.

Pick a night when the Moon is a crescent. - Page 13 Use a neutral density filter (sometimes called a “moon filter”) when observing the Moon. Neutral density filters are available from Meade as an optional accessory. Spend several nights observing the Moon. Some nights, the Moon is so bright that it makes other objects in the sky difficult to see.
