Star Pointer Operation The star pointer is powered by a long life 3-volt lithium battery (#CR2032) located underneath the front portion of the Star Pointer. Like all finderscopes, the Star Pointer must be properly aligned with the main telescope before it can be used. This is a simple process using ...

The NexStar 4 has a removable hand controller built into the side of the fork arm designed to give you instant access to all the functions the NexStar has to offer.

4. Catalog Keys: The NexStar has a key on the hand control to allow direct access to each of the catalogs in its 40,000 object database. The NexStar contains the following catalogs in its database: Messier – Complete list of all Messier objects. NGC – Select list of all the deep-sky objects in the R...

Each alignment method is discussed in detail below. Sky Align Sky Align is the easiest way to get your NexStar aligned and ready to observe. Ev...

5. If the finderscope has been properly aligned with the telescope tube, the alignment star should now be visible inside the field of view of the eyepiece. The hand control will ask that you center the bright alignment star in the center of the eyepiece and press the ALIGN button. This will accept t...

Never look directly at the sun with the naked eye or with a telescope (unless you have the proper solar filter). Permanent and irreversible eye damage may result. 1. Select Solar System Align from the alignment options. 2. Press ENTER to accept the time/site information displayed on the display, or ...

7. The telescope then asks you to center in the eyepiece the alignment object you selected. Use the direction arrow buttons to slew the telescope to the alignment object and carefully center it in the finderscope. Press ENTER when centered. 8. Then, center the object in the eyepiece and press ALIGN....

D D i i r r e e c c t t i i o o n n B B u u t t t t o o n n s s The NexStar has four direction buttons in the center of the hand control which control the telescope motion in altitude (up and down) and azimuth (left and right). The telescope can be controlled at nine different speed rates. 1 = .5x 6...

This rate compensates for the rotation of the earth by moving the telescope at the same rate as the rotation of the earth, but in the opposite direction. When the telescope is polar aligned, this can be accomplished by moving the telescope in Right Ascension only. When mounted in Alt-Az mode, the te...

Up to this point, this manual covered the assembly and basic operation of your NexStar telescope. However, to understand your telescope more thoroughly , you need to know a little about the night sky. This section deals with observational astronomy in general and includes information on the night sk...

Figure 6-3 This is how the telescope is to be set up for polar alignment. The tube should be parallel to the fork arm which should be pointed to Polaris.

Based on your current alignment, NexStar will slew to where it thinks Polaris should be. Use the tripod’s tilt plate adjustment to place Polaris in the center of the eyepiece. Do not use the hand control’s direction buttons to position Polaris. Once Polaris is centered in the eyepiece, press ENTER; ...
