ADJUSTING THE HORIZONTAL AND
VERTICAL TENSION OF THE OPTICAL TUBE
If the horizontal and/or vertical movement of
the optical tube seems to be too loose or too
tight, you can adjust the amount of tension in
the movement of the optical tube to suit your
own preference. To adjust the horizontal
tension of the optical tube, use an adjustable
wrench or nut driver to tighten or loosen the
horizontal adjustment nut located under the
base of the telescope. See F
Fiig
g.. 7
7.
To adjust the vertical tension of the optical
tube, first loosen the attachment knobs (11)
and remove the optical tube from the bracket.
Use an adjustable wrench or nut driver to
tighten or loosen the vertical adjustment nut
located on the inner side of the bracket. See
F
Fiig
g.. 8
8. Check the amount of tension by moving
the bracket up and down before
reattaching the optical tube.
OPTIONAL ACCESSORIES
#928 45° Erecting Prism (1.25 O.D.):
Correctly orients the telescopic image
during terrestrial observing and yields an
image position at a 45° angle to the main
telescope tube, resulting in a more
comfortable observing position in
most cases.
Additional Eyepieces (1.25 inch barrel
diameter):
For higher or lower
magnifications with the telescopes that
accommodate 1.25 inch eyepieces, Meade
Series 4000 Super Plössl eyepieces,
available in a wide variety of sizes, provide a
high level of image resolution and color
correction at an economical price. Contact
your Meade Dealer or see the Meade catalog
for more information. Visit us on the web at
www.meade.com.
Looking at or near the
Sun
will cause
irreversible
damage to your eye. Do not point this telescope at or near the Sun. Do not look through the telescope as it is moving.
