efore you begin
B
Follow the instructions for your specific
model in the manual. Read the entire instructions
carefully before beginning. Your telesope should
be assembled during daylight hours. Choose a
large, open area to work to allow room for all
parts to be unpackaged.

Never use your telescope to look directly at the sun.
Permanent eye damage will result. Use a proper solar
filter for viewing the sun. When observing the sun,
place a dust cap over your finderscope to protect it
from exposure. Never use an eyepiece-type solar filter
and never use your telescope to project sunlight onto
another surface, the internal heat build-up will damage
the telescope optical elements.

Telescope should be balanced before each observing session. Balancing reduces stress on telescope mount
and allows precise control of micro-adjustement. A balanced telescope is specially critical when using the
optional clock drive for astrophotography.
The telescope should be balanced after all accessories (eyepiece, camera, etc.) have been attached. Before
balancing your telescope, make sure that your tripod is balanced and on a stable surface. For photography,
point the telescope in the direction you will be taking photos before preforming the balancing steps.
telescope
1) Focus the telescope eyepiece on a distant object.
2) Once the object has been centered in the telescope
view, ensure the locking screws are tightened.
3) Use the three alignment screws to center the
finderscope crosshairs on the object seen in the
telescope view (Fig.a).
Depending on telescope design, the object may appear
inverted in the telescope view.
Do not over-tighten the three alignment screws
on the finderscope mount.
R.A. Balancing
1) Adjust altitude of the mount to between 15º and 30º by
using the altitude adjustment T-bolt.
2) Slowly unlock the R.A. and Dec. lock knobs.
Rotate the telescope unitl both the optical tube
and counterweight rod is horizontal to the ground,
and the telescope tube is to the side of the mount. (Fig. b)
3) Tighten the Dec. lock knob.
4) Move counterweight along counterweight rod until
telescope is balanced and remains stationary when released
5) Tighten counterweight thumb screws to hold the counterweight
in its new position.
Dec. Balancing
All accessories should be attached to the telescope before
commencing with balancing the declination axis. The R.A.
axis should be balanced before proceeding with Dec. balancing.
1) Adjust altitude of the mount to between 60º and 75º.
2) Release the R.A. lock knob and rotate R.A. axis so that the
counterweight rod is in horizontal position. Tighten the R.A. thumbscrew.
3) Unlock the Dec. thumbscrew and rotate telescope tube until it is paralled to the ground.
4) Slowly release telescope and determine which direction the telescope rotates. Loosen
telescope tube rings and slide telescope tube forward or backward in the clamps
to balance Dec. axis.
5) Once telescope no longer rotates from its parallel starting position, re-tighten tube rings
and the Dec. lock knob. Reset altitude axis to your local latitude.

the EQ1 mount
The equatorial mount has controls for both conventional
altitude (up-down) and azimuthal(left-right) directions of
motion. These two directions are recommended for large
direction changes and for terrestial viewing. Use the large
knurled knob near the base of the mount for azimuthal
adjustments, and the altitude adjustment T-bolts for
altitude adjustments. (Fig. c)
In addition, this mount has right ascension (hour angle)
and declination direction controls for polar-aligned
astronomical observing. Loosen the lock knobs to
make large direction changes. Use the control cable
for fine adjustment after the lock knobs have all
been locked. (Fig. d)

To magnify images in the telescope, you need to insert an eyepiece (ocular) into the end of the focuser
assembly. Insert the desired eyepiece and lightly tighten the thumbscrews to hold the eyepiece in place.
Barlow lens can be used to increase magnification of the eyepiece. Install the barlow lense directly into
the end of the focuser, then insert the eyepiece into the barlow lense. (Fig. f)
To locate an object in the eyepiece, first locate the object in the
finderscope view. The finderscope allows magnification of a
larger area than the higher power telescope view. Finderscope
should be aligned during daytime before use.
The focus knobs at the base of the focuser uses a rack-and-pinion
system to focus the magnified images seen through the telescope.
Eyepiece
Turn the knobs slowly until the objects are in focus.
roper care for your telescope
P
Replace the dust cap over end of telescope whenever not in use. This prevents dust from settling on mirror
or lens surface. Do not clean mirror or lens unless you are familiar with optical surfaces. Clean finderscope
and eyepieces with special lens paper only. Cleaning and aligning of optical elements should be preformed
by an experienced technician every two years. Eyepieces should be handled with care, avoid touching
optical surfaces.

Telescopes require about 30 minutes to equalize with surrounding temperature and humidity. This minimizes
heat wave distortion inside telescope tube and allows telescope to adapt to ambient moisture conditions.
