Aligning the Finderscope

To make the alignment process a little easier, you should perform this task in the daytime when it is easier to locate objects in the telescope without the finder. To align the finder:

1.Choose a conspicuous object that is in excess of one mile away. This will eliminate any possible parallax effect between the telescope and the finder.

2.Point your telescope at the object you selected and center it in the main optics of the telescope.

3.Lock the azimuth and altitude clamps to hold the telescope in place.

4.Check the finder to see where the object is located in the field of view.

5.Adjust the nylon thumb screws on the finder bracket, tightening one while loosening another, until the cross hairs are centered on the target.

6.Tighten each thumb screw a quarter of a turn to ensure that they will not come loose easily.

The image orientation through the finder is inverted (i.e., upside down and reversed from left-to-right). Because of this, it may take a few minutes to familiarize yourself with the directional change each screw has on the finder

Powering the NexStar

The NexStar can be powered by the supplied 12v AC adapter or optional car battery adapter (see Optional Accessories section in the back of this manual). Use only the AC adapter supplied by

Celestron. Using any other adapter may damage the electronics and will void your manufacturer's warranty.

1.To power the NexStar with the 12v AC adapter (or car battery adapter), simply plug the round post into the 12v outlet on the bottom portion of the drive base and plug the adapter into a wall outlet (or cigarette lighter outlet for the car battery adapter).

2.Turn on the power to the NexStar by flipping the switch, located next to the 12v outlet, to the "On" position.
