perating the HEQ5/EQ6 mount

The EQ6 mount has controls for both conventional altitude (up-down)

and azimuthal (left-right) directions of motion. Use the altitude

adjustment T-bolts for altitude adjustments. The two T-bolts work

against each other to move the mount in altitude or azimuth. It is

important to loosen one T-bolt before tightening the other. Over-

tigtening can cause the bolts to bend or break. The azimuthal axis is

changed by the two azimuth adjustment knobs located near the tripod

head. These provide fine-adjustment of azimuth for polar aligning

(Fig.c).

In addition, this mount has direction controls for polar aligned

astronomical observing. These directions use Right Ascension

(east/west) and Declination (north/south) axis. There are two options

to move the telescope in these directions: For large and quick

movement, loosen the R.A. lock lever or the Dec. lock lever (Fig.c-1).

For fine adjustments, use the motor drive hand control (see "Using

the Hand Control").

There are three numerical scales on this mount. The lower scale on

the side of the mount is used for polar alignment of the telescope to

your local latitude. The R.A. (Right Ascension) scale measures hour

angle and is adjustable to your local meridian. The declination scale is

located near the top (EQ6) or the counterweight rod (HEQ5) of the

mount.

The N/Off/S switch acts as a power switch as well as controller for

the directions of the motors. The "N" position allows R.A. motor to

track for the Northern Hemisphere observations and the "S" position

is suitable for the Southern Hemisphere (Fig.d). When the EQ6 Hand

Control is turned on and all buttons are depressed, the R.A. motor

will rotate at the proper speed to compensate for the earth's rotation.

The Dec. axis does not automatically rotate. When the mount is

correctly polar aligned, you only need to turn the R.A. slow-motion to

follow or track objects as they move through the field. The Dec.

control is not needed for tracking.

The four push buttons control the directions of the motors. The up-

down buttons control the declination motor while the left-right buttons

change the R.A. axis.

The rate switch allows for changes to the speed rate of the motors

from high speed slew rate (16X or fast) to slow micro-adjustment

(2X) and the speed in between (8X). When the rate switch is set on

"2X", pressing the right R.A. button will rotate the telescope forward at

twice the tracking speed or approximately ½º per minute. The left

R.A. button stops all motion and allows stars to drift by at their

normal rotation rate of approx. ¼º per minute. The "8X" setting moves

the telescope forward at 8 times the tracking rate and the left button

moves the telescope backwards at 7 times the tracking rate. The

"Fast" or "16X" setting allows forward at 16 times the tracking rate and

the left button moves the telescope backwards at 15 times the

tracking rate. When the reverse switches on the side of the hand

control are set on "REV" (Fig.d-1), the four push buttons act in

reverse. For example, when the upper switch is set to "REV",

pressing the left R.A. button moves the telescope forward, and the

right R.A. button moves the telescope backwards.
