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. These
allow fine-adjustment for setting the mount to your local
latitude. The azimuthal axis is changed by the two azimuth
adjustment knobs located near the tripod head. These allow
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 under the R.A. shaft or the Dec. lock lever near the
top of the mount (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 is measures hour angle and is adjustable
to your local meridian. The declination scale is located near
the top of the mount (Fig.c-2).

The N/Off/S switch acts as a power switch as well as
controlling 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 changes to the speed rate of the
motors from high speed slew rate (16X) 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" settings allows
forward at 8 times the tracking rate and the reverse button
moves the telescope backwards at 7 times the tracking rate.
The "16X" setting allows forward at 16 times the tracking rate
and the reverse button moves the telescope backwards at 15
times the tracking rate.
