objective lens, tilt the objective (front) lens face down, and wait until the telescope reaches room
temperature.
With the diagonal mirror already attached and in place, we recommend starting your viewing with the
low power 20mm eyepiece because it gives you the widest angle with the brightest and sharpest
views. To adjust the angle of the telescope, loosen the azimuth lock knob by turning it
counterclockwise. Adjust the telescope to the desired angle, then tighten the azimuth lock knob.
NOTE: When using the diagonal mirror, objects will appear right-side up in your telescope, but
reversed, like a reflection in a mirror. This is normal, and does not indicate a defect.
USING YOUR TELESCOPE FOR TERRESTRIAL (LAND) VIEWING:
The brightest images will be seen when you use the 20mm eyepiece in conjunction with the diagonal
mirror. The mirror reversed image, however is confusing. This can be corrected with the included 2X
Image Erector. Te choice is yours.
To use the 2X Image Erector, remove the diagonal mirror. Insert the 2X Image Erector. Then insert
the 20mm eyepiece into the 2X Image Erector. The image seen will now be right side up and
correctly oriented.
As well as providing proper image orientation the 2X Image Erector also doubles the magnification
power of the eyepiece used. The effect is shown below. Remember that the brightness of the viewed
image decreases as the magnification power increases.

CARE AND CLEANING OF OPTICS:
Optical components of a telescope get dirty over time. Dirt or dust on a lens should be removed only
with the utmost care. A considerable amount of dirt or dust would have to accumulate on the optical
surface before your view would be compromised.
1.) Keeping any dust caps on during storage and transport will reduce dust collection.
2.) Condensation may collect on the optical surfaces when the telescope is not in use. Remove the
dust caps and allow the moisture to evaporate naturally. Point the telescope downwards to minimize
the accumulation of airborne dust.
3.) Once all moisture has evaporated, replace the dust caps.
