Celestron STAR HOPPER Instruction Manual page 4

The Pinnacle mirror cell features a mirror adjustment system that allows for fast collimation when using the
supplied collimation tool.
Our unique and heavy duty, single vane secondary mirror bracket creates minimal obstruction. This allows more
light to reach the primary mirror, which in turn provides a brighter image and better resolution.
Inner Diameter Tubes
Celestron's Star Hopper® Dobsonians (6"and 8") have their primary mirrors housed in oversized, flat black,
anti-reflective painted tubes, which reduce light scatter and tube currents, increasing image sharpness. These large
telescope tubes also increase image contrast and improve "seeing" when viewing planets and the moon.
Rack and Pinion Focuser
1
The Star Hoppers use a Rack and Pinion focuser which accepts 1 / " oculars. This type of focuser is more
4
convenient to use than helical focusers, which many other Dobsonians feature.
CAUTION: READ THIS SECTION BEFORE USING YOUR TELESCOPE
Your Celestron Star Hopper telescope is designed to give you hours of fun and rewarding observations.
®
However, there are a few things to be aware of before using your telescope that will ensure your safety and protect
your equipment.
NEVER LOOK DIRECTLY AT THE SUN WITH THE NAKED EYE OR WITH A TELESCOPE. NEVER
POINT YOUR TELESCOPE AT THE SUN UNLESS YOU ARE USING THE PROPER SOLAR FILTER.
PERMANENT AND IRREVERSIBLE EYE DAMAGE MAY RESULT.
NEVER USE YOUR TELESCOPE TO PROJECT AN IMAGE OF THE SUN ONTO ANY SURFACE.
INTERNAL HEAT BUILD-UP CAN DAMAGE THE TELESCOPE AND/OR ANY ACCESSORIES THAT
MAY BE ATTACHED TO IT.
NEVER LEAVE YOUR TELESCOPE UNSUPERVISED, ESPECIALLY WHEN CHILDREN ARE PRESENT.
THIS ALSO HOLDS TRUE FOR ADULTS WHO MAY NOT BE FAMILIAR WITH THE CORRECT
OPERATING PROCEDURES FOR YOUR TELESCOPE.
NEVER USE AN EYEPIECE SOLAR FILTER OR A HERSCHEL WEDGE. INTERNAL HEAT BUILD-UP
WITHIN THE TELESCOPE CAN CAUSE THESE DEVICES TO CRACK, BREAK OR DAMAGE YOUR
TELESCOPE. ANY SOLAR FILTER USED SHOULD BE A FILTER FOR THE PRIMARY LENS, SUCH AS
CELESTRON'S SOLAR SKREEN (SEE OPTIONAL ACCESSORIES ON PAGES 23- 24 ).
ALWAYS COVER A FINDERSCOPE (IF INSTALLED) WHEN USING YOUR TELESCOPE WITH THE
CORRECT SOLAR FILTER. ALTHOUGH SMALL IN APERTURE, THIS INSTRUMENT HAS ENOUGH
LIGHT GATHERING POWER TO CAUSE PERMANENT AND IRREVERSIBLE EYE DAMAGE. THE
IMAGE PROJECTED BY THE FINDERSCOPE IS HOT ENOUGH TO BURN SKIN OR CLOTHING.
