CONGRATULATIONS ON YOUR PURCHASE OF THE CASSINI C-90080EQ1 TELESCOPE.

C A S S I N I

PRODUCED TO PRECISE SPECIFICATIONS.

PRIOR TO USING YOUR NEW CASSINI TELESCOPE, PLEASE READ THE FOLLOWING SETUP

AND USAGE INSTRUCTIONS. IT IS IMPORTANT TO PROPERLY ASSEMBLE YOUR TELESCOPE

IN ORDER TO ALLOW IT TO FUNCTION PROPERLY.

CONSIDER USING THE TELESCOPE FOR EARTH (TERRESTRIAL) VIEWING BEFORE

ATTEMPTING TO VIEW ASTRONOMICAL OBJECTS. THIS WILL FAMILIARIZE YOU WITH HOW

POWERFUL EACH EYEPIECE WILL BE, AS WELL AS INTRODUCING YOU TO THE FUNCTIONS

OF YOUR ACCESSORY LENSES.

DUE TO THE DIAGONAL MIRROR POSITIONED IN THE FOCUS HOUSING, THE IMAGE YOU

SEE WILL ALWAYS BE RIGHT SIDE UP. BUT LEFT AND RIGHT ARE REVERSED.

WE RECOMMEND YOU BEGIN WITH THE LOWEST POWER EYEPIECE, 25MM, WHEN USING

YOUR TELESCOPE. AS YOU INCREASE THE POWER TO 10MM, YOUR POWER WILL BE HIGHER,

BUT THE IMAGE WILL APPEAR DARKER; THIS IS DUE TO THE BASIC PHYSICAL PROPERTIES OF

THE TELESCOPE. THE HIGHER THE POWER YOU USE THE DARKER THE IMAGE WILL

APPEAR AND YOUR VIEWING FIELD WILL BE MORE NARROW.

PLEASE BE PATIENT WHEN USING YOUR TELESCOPE. IT IS A VERY SENSITIVE INSTRUMENT

THAT IS CAPABLE OF USING HIGH POWERS. HOWEVER, THE MORE POWER YOU USE, THE

MORE SENSITIVE THE TELESCOPE BECOMES. AS A RESULT, THE SLIGHTEST MOVEMENT OF

THE TELESCOPE COULD CAUSE YOU TO LOSE THE IMAGE YOU HAVE IN YOUR EYEPIECE.

PRACTICE WILL ENABLE YOU TO KNOW HOW MUCH MOVEMENT TO EXPECT WITH EACH

EYEPIECE AND IT'S CORRESPONDING POWER.

THIS TELESCOPE HAS BEEN CORRECTED AGAINST CHROMATIC ABERRATION AND

FOCUSING HOUSING.

3) EYEPIECE INSERTION

STARTING WITH THE LOWEST POWER AND

THEN GOING UP.

4) BARLOW LENS

THE BARLOW LENS IS USED TO ACHIEVE

THE MAXIMUM POWER FROM YOUR

TELESCOPE. FIRST, REMOVE THE DIAGONAL

MIRROR FROM THE FOCUSING TUBE AND

INSERT THE BARLOW LENS DIRECTLY INTO

THE FOCUSING TUBE. YOU WILL HAVE TO

READJUST YOUR FOCUSING DUE TO THE FACT

THAT YOU HAVE INCREASED/DECREASED THE

POWER OF YOUR TELESCOPE DRAMATICALLY.

TAKE THE TIME TO BECOME FAMILIAR WITH YOUR NEW TELESCOPE. LEARN THE NAMES

OF THE VARIOUS PARTS, WHERE THEY ARE LOCATED AND THEIR FUNCTION. IT IS BEST TO

PERFORM THESE FUNCTIONS DURING THE DAY TIME.

WHEN SETTING UP FOR A VIEWING SESSION, PLACE THE TELESCOPE IN AN AREA

SHELTERED FROM THE WIND IF POSSIBLE. THE BEST NIGHT TIME VIEWING WILL BE AWAY

FROM CITY LIGHT AND WHEN THE ATMOSPHERE IS "STEADY".

WITH A LITTLE PRACTICE YOU WILL LEARN TO JUDGE WHEN VIEWING CONDITIONS ARE

GOOD. LOOK FOR THE NIGHTS WHEN THE STARS SHINE BRIGHTLY WITH LITTLE OR NO

TWINKLING.

USE LOW POWER TO TAKE ADVANTAGE OF THE WIDER FIELD OF VIEW AND BRIGHTER

IMAGE. RESERVE YOUR HIGHER POWERS FOR THOSE NIGHTS WHEN VIEWING

CONDITIONS ALLOW FOR DETAILED OBSERVATIONS.

THE EYEPIECES BY 3 TIMES.

TO USE SIMPLY INSERT THE BARLOW LENS INTO THE MAIN FOCUSING TUBE AND THEN PUT

THE DESIRED EYEPIECE INTO THE RECEIVING END OF THE BARLOW LENS.

PLEASE REMEMBER, THE HIGHER THE POWER YOU USE THE DARKER THE IMAGE WILL

APPEAR.
