Instruction Manual

Observe the Moon

Point your telescope at the Moon (note that the Moon is not visible every night).

Use the handbox to practice using the arrow keys and the slew speeds to view

different features. The Moon contains many interesting features, including cra-

ters, mountain ranges, and fault lines. The best time to view the Moon is during

its crescent or half phase. Sunlight strikes the Moon at an angle during these

periods and adds a depth to the view. No shadows are seen during a full Moon,

making the overly bright surface to appear flat and rather uninteresting. Consider

the use of a neutral density Moon filter when observing the Moon. Not only does

it cut down the Moon‘s bright glare, but it also enhances contrast, providing a

more dramatic image.

Tracking Objects

As the Earth rotates beneath the night sky, the stars appear to move from East

to West. The speed at which the stars move is called the sidereal rate. You can

setup your telescope to move at the sidereal rate so that it automatically tracks

the stars and other objects in the night sky. The tracking function automatically

keeps an object more or less centered in the telescope’s eyepiece.

To automatically track objects, you first need to learn how to set the polar home

position of your telescope and then how to select „Targets: Astronomical“ from the

Handbox Setup menu.

Setting the Polar Home Position

1. Level the mount, if necessary, by adjusting the length of the three tripod

legs.

2. Unlock the R.A. Lock (17, Fig. 1a). Rotate the Optical Tube Assembly until

the counterweight shaft is pointing straight down over the mount. See Figs.

16a and 16b.

3. If you have not already done so, lift the telescope assembly and turn it so the

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

faces North (or South in the Southern Hemisphere). Release the Dec. lock

(1, Fig. 1a) of the tripod, so that the optical tube may be rotated. Rotate the

optical tube until it points North (or South in the Southern Hemisphere). Then

re-tighten the lock. Locate Polaris, the North Star, if necessary, to use as an

accurate reference for due North (or Sigma Octantis in the Southern

Hemisphere). See LOCATING THE CELESTIAL POLE, page 30.

4. If you have not already done so, determine the latitude of your observing

location. See APPENDIX C: LATITUDE CHART, page 41, for a list of latitudes of

major cities around the world. Use the latitude T-handle screws (10, Fig. 1a)

to tilt the telescope mount so that the pointer indicates the correct latitude of

your viewing location on the latitude dial (12, Fig. 1a). See step 4, page 10

for more information.

5. If steps 1 through 4 above were performed with reasonable accuracy, your

telescope is now sufficiently well-aligned to Polaris, the North Star, for you

to begin making observations.

Once the mount has been placed in the polar home position as described above,

the latitude angle need not be adjusted again, unless you move to a different

geographical location (i.e., a different latitude).

Important Note: For almost all astronomical observing requirements,

approximate settings of the telescope’s latitude and other settings are

acceptable. Do not allow undue attention to precise settings of polar

home position of the telescope to interfere with your basic enjoyment

of the instrument.

Note: If you wish to

perform a more precise

polar alignment for the

purposes of astrophotog-

raphy, see „Appendix B,“

page 31.
