Instruction Manual

4. The handbox then chooses three stars from its database to align upon. When the

telescope slews to a star for alignment, it may not appear in the field of view in the

eyepiece. Use the Arrow keys to move the telescope until the star is visible and

centered in the eyepiece. The alignment star should be easily recognized and be

the brightest star in the area of the sky where the telescope is pointing. See

WHICH

ONE‘S THE ALIGNMENT STAR

, page 13, for more information. When the star is

centered, press ENTER. Repeat the procedure for the second and third alignment

stars.

Note: The handbox locates alignment stars based on the date, time, and

location entered. The alignment stars may change from night to night.

All that is required is for the observer to center the selected star in the

eyepiece when prompted.

Method #2: Axis Alignment Procedures

In order for the equatorial mount to accurately point to astronomical objects using

the GO TO feature of the handbox, the optical axis of the optical tube must be

aligned with the R.A. axis of the mount. In most cases, the telescope will perform

adequately without making any adjustments, but performing one of the following

alignment methods before the initial use of the telescope, and periodically thereafter,

will increase the mount’s pointing accuracy.

When the optical axis is perfectly aligned to the R.A. axis and the declination set to 90°,

all objects will rotate about a point in the center of the eyepiece, as the mount is rotated

about the R.A. axis. A misalignment in elevation results in the center of rotation shifting

up or down. A misalignment in attitude results in the center shifting left or right.

The telescope is moved manually in Method #1 to correct for attitude misalignment

and then for elevation misalignment. The handbox moves the telescope in Method

#2.

Procedure #1: To correct for attitude misalignment

Important Note: Throughout the following procedures, the directional refer-

ences up/down/left/right are used. No matter which type of telescope model

you are using, these directions are to be interpreted relative to real-world

targets. For example, left/right moves the image along the horizon, and up/

down moves the image vertically.

Perform this procedure during the daytime. You will need to have a clear line of

sight to a wide, distinct landmark with a clear, horizontal feature.

1. Plug in the handbox and turn on the power as described previously in this

manual. You will use handbox‘s Arrow keys in the course of this procedure.

2. Loosen the R.A. Lock (17, Fig. 1a) and the Dec. Lock (1, Fig. 1a). Point the

tube so that the tripod leg below the Fine Azimuth Control Knobs (11, Fig. 1a)

approximately faces North (or South in the Southern Hemisphere). Retighten the

Dec. Lock. Move the counterweight shaft and mount so that it is parallel to the

horizon. This is position A. See Fig. 45. Retighten the R.A. Lock.

3. Rotate the optical tube (you will need to loosen the cradle ring lock knobs to do

so) to make sure the focuser extends horizontally from the optical tube while in

position A and do not rotate the tube for the remainder of the alignment proce-

dure.

4. Adjust the tripod legs, polar axis altitude and/or polar axis azimuth so that the

wide, horizontal object you have chosen as a target is positioned across the

middle of the eyepiece.
