CARBON FIBER SERIES
Welcome To Our ED Triplet Carbon Fiber Series
Designed to deliver crystal clear imagery rich in contrast, the premium telescopes
in our ED Triplet Carbon Fiber Series are the ideal optical instruments to capture the
universe’s breathtaking sights. Available in four apertures ranging from a grab-and-
go 80mm to a far-reaching 152mm, these apochromatic refractors produce stunning
views of countless celestial treasures like the Moon’s chiseled craters, Saturn’s
elegant rings or the churning spiral of the face-on Pinwheel Galaxy. To provide you
a true view of the cosmos, the telescopes in this series feature an air-spaced triplet
optical design that virtually eliminates chromatic aberrations. In addition, they use a
combination of genuine HOYA extra-low dispersion (ED) glass and proprietary EMD
enhanced multi-layer coatings on all optical surfaces to generate brilliant high-contrast
images with crisp definition. The quality of the optics also allows those seeking to push
magnification based on their choices of eyepieces or focal extenders to do so without
sacrificing clarity. To further guarantee precision performance, these telescopes include
a three-point collimation cell that allows for pinpoint adjustments of the objective lens
and a carbon fiber optical tube assembly that eliminates focus change attributed to
shrinking or expansion caused by temperature fluctuations. Your ED Triplet Carbon
Fiber Series telescope offers all of these benefits and more. This set-up manual and the
accompanying materials will guide you through a basic assembly process that will have
you at the eyepiece and under the stars in no time.
SUN WARNING
DO NOT use this telescope or any accompanying finder scope to look at or near the Sun!
Even momentary visual contact with the Sun’s light rays can instantly cause irreversible
damage to your eye(s). Eye damage can be painless, so there is no warning to the
observer that damage has occurred until it is too late.
Take extra care when using the telescope or a finder scope during daylight hours, and
do not point either at or near the Sun. Do not look through either when you are moving
the instruments during the daytime. Never allow anyone to use the telescope or a finder
scope during the daytime without warning them of the hazards of aiming either at or
near the Sun. Make sure that they are adequately trained on the use of these instruments
before allowing them to start observing. Children should always have informed and
trained adult supervision while observing.
PROPER CARE WARNING
Your telescope is a precision optical device and keeping the optics free of dust and dirt
is crucial for optimal performance. However, the use of improper cleaning techniques,
tools and/or solutions can cause irreparable damage to your telescope. In terms of
solutions, use distilled water and/or pure isopropyl alcohol (99%). Do not eat, drink
or smoke while using this substance, wear protective gloves and eyewear, use in a
ventilated area and follow proper disposal techniques. Only use pure cotton swabs/balls
or white, unscented, lotion-free tissues for wiping down optics after you have removed
as many particles as possible with forced air or a photographic-grade camel hair brush.
DO NOT use optical lens cleaning tissues as many contain fiberglass particles that can be
abrasive.
