Operation

The EZ Finder II works by projecting a tiny red dot onto a lens mounted in the front of the unit. When you look through the EZ Finder II, the red dot will appear to float in space, helping you locate even the faintest of deep space objects. The red dot is produced by a light-emitting diode (LED) near the rear of the sight. A 3-volt lithium battery provides the power for the diode.

Turn the power knob clockwise until you hear the “click” indi- cating that power has been turned on. Look through the back of the reflex sight with both eyes open to see the red dot. Position your eye at a comfortable distance from the back of the sight. In daylight you may need to cover the front of the sight with your hand to be able to see the dot, which is purposefully quite dim. The intensity of the dot is adjusted by turning the power knob. For best results when stargazing, use the dimmest possible setting that allows you to see the dot without difficulty. Typically a dimmer setting is used under dark skies and a bright setting is used under light-polluted skies or

daylight .

When you have located your target, be sure to turn the power knob counterclockwise until it clicks off to preserve your bat- tery. When the white dots on the EZ Finder II’s body and power knob are lined up, the EZ Finder II is turned off.

Attaching the Hand Control

The StarSeeker hand control has a phone jack type connec- tor at the end of its cord. Plug the phone jack connector into the outlet at the base of the telescope’s fork arm (Figure 4). Push the connector into the outlet until it clicks into place and place the hand control into its holder as described previously in the Assembly section of the manual.

Powering the StarSeeker

The StarSeeker can be powered by the supplied battery pack, or an optional 12v AC adapter or Dynamo Pro Field Battery. The battery pack requires 8 user supplied AA size alkaline batteries. To power the StarSeeker, insert the plug of your desired power supply into the 12v jack located on the side of the fork arm. Once the power supply is plugged in, the

StarSeeker will power on and the hand control will display the message NexStar GT. To turn the StarSeeker off, simply dis-

connect the power supply from the jack on the mount.

Important: The first time the StarSeeker is used, it will request information to help identify the model of telescope.

Once powered on, the hand control will display the message Select Model. Use the Up and Down menu keys (10) to scroll

through the different StarSeeker models. Press ENTER when your StarSeeker model is displayed on the hand control. This information will be retained for future use and will not be dis- played again. If for some reason the incorrect model was selected or you wish to use your hand control on a different StarSeeker model, the Select Model utility feature allows you

The Hand Controller

This section describes the basic hand control procedures needed to operate the StarSeeker. These procedures are grouped into three categories: Alignment, Setup and Utilities. The alignment section deals with the initial telescope align- ment as well as finding objects in the sky; the setup section discusses changing parameters such as tracking mode and tracking rate; finally, the Utility section reviews all of the addi- tional features such as adjusting the telescopes slew limits and backlash compensation.

1.Liquid Crystal Display (LCD) Window: Has a dual-line, 16 character display screen that is backlit for comfortable viewing of telescope information and scroll- ing text.

2.Align: Instructs the StarSeeker to use a selected star or object as an alignment position.

3.Direction Keys: Allows complete control of the StarSeeker in any direction. Use the direction keys to move the telescope or center objects in the EZ Finder II and eyepiece.

4.Catalog Keys: The StarSeeker has a key on the hand control to allow direct access to each of the catalogs in its 4,000+ object database. The StarSeeker contains the following catalogs in its database:

Messier - Complete list of all Messier objects.

NGC - Many of the brightest deep sky objects from the Revised New General Catalog.
