Congratulations on your purchase and welcome to the Celestron world of amateur astronomy. Some of the terms

and parts described in these instructions may be new to you, so a few commonly used terms you'll want to be

familiar with are defined below.

Altazimuth mount - the simplest type of mount, with two motions: altitude (up and down) and azimuth (side-to-

side). "Mount" refers to the part of the telescope that supports the tube, which carries all the telescope's optics.

Altitude lock - allows the telescope tube to be locked into place once a focused image has been set up, by tightening

the two screws on the outside of the altazimuth mount.

Focal length - the distance from the optical center of the lens to the point where the incoming light rays converge,

creating a clear, focused image.

Objective lens - the front lens of the telescope. It gathers incoming light to create a sharply focused image.

Refracting telescope - a long, thin tube where light passes in a straight line from the front objective lens directly to

the eyepiece at the opposite end of the tube.

First, you need to take the time to familiarize yourself with the parts of your PowerSeeker telescope, then assemble

it, following the easy instructions provided. Next, read over the operating instructions and become familiar with how

your telescope works, to prepare for hours of viewing enjoyment.

CAUTION: READ THIS SECTION BEFORE USING YOUR TELESCOPE

Your PowerSeeker telescope is designed to give you hours of fun and rewarding observing. 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'RE 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, OR USE AN

EYEPIECE SOLAR FILTER OR A HERSCHEL WEDGE. 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.

ALWAYS COVER THE FINDERSCOPE 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.
