INTRODUCTION
THIS TELESCOPE HAS BEEN CORRECTED AGAINST CHROMATIC ABERRATION AND
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 MIRROR DIAGONAL 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, 20MM, WHEN USING
YOUR TELESCOPE. AS YOU INCREASE THE POWER TO 6MM, 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.
TO MOUNT:
1) REMOVE MARS-EYE ELECTRONIC FINDER FROM BOX.
2) LOOSEN THUMB SCREWS ON SIDE OF FINDER AND SLIDE FINDER ONTO DOVETAIL
MOUNT LOCATED AT TOP OF MAIN TELESCOPE TUBE.
3) TIGHTEN THUMB SCREWS.
TO CHECK ALIGNMENT WITH MAIN TELESCOPE:(IMPORTANT!)
1) THE MARS-EYE ELECTRONIC FINDER IS NOT PRE-SET AT FACTORY. THE FOLLOWING
WILL ALLOW YOU TO ADJUST THE ALIGNMENT.
2) DURING THE DAY LIGHT HOURS, AIM THE MAIN TELESCOPE AT AN OBJECT AT LEAST 1/4
MILE OR MORE IN THE DISTANCE AND BRING IT INTO FOCUS.(VERY IMPORTANT)
3) ONCE YOU HAVE CENTERED THE REFERENCE ITEM IN THE MAIN TUBE, TIGHTEN ALL
KNOBS AND ADJUSTMENTS TO PREVENT ANY MOVEMENT.
4) REMOVE CIRCULAR BATTERY SAVER LOCATED BENEATH FRONT OF FINDER (BE SURE.
TO SAVE AND REPLACE THE BATTERY SAVER WHEN NOT IN USE.)
5) TURN FINDER ON BY SLIDING ON/OFF SWITCH FORWARD. ON/OFF SWITCH IS LOCATED
ON THE RIGHT SIDE OF THE FINDER.
6) LOOK THROUGH THE FINDER AND LOCATE THE RED DOT.
7) IF THE OBJECT IN THE MARS-EYE FINDER IS NOT THE OBJECT YOU SEE THROUGH THE
MAIN TELESCOPE TUBE, ADJUSTMENT IS REQUIRED.
8) TO MOVE THE RED DOT UP AND DOWN, SIMPLY TURN THE ELEVATION SCREW LOCATED
ON THE REAR BOTTOM OF THE FINDER TO HEIGHT REQUIRED.
9) TO MOVE THE RED DOT LEFT AND RIGHT, SIMPLY TURN THE WINDAGE SCREW LOCATED
AT THE FRONT LEFT SIDE OF THE FINDER TO THE PROPER POSITION.
10) THESE ADJUSTMENTS WILL ALLOW YOU TO POSITION THE RED DOT ON THE SAME
OBJECT CENTERED IN THE MAIN TELESCOPE.

HOW TO USE EYEPIECES & ACCESSORIES
PROPER PLACEMENT OF THE EYEPIECES AND ACCESSORIES IS IMPORTANT IN ORDER TO
ASSURE EASY OPERATIONS AND CLEAR VIEWING.
PLEASE USE THE ACCESSORIES IN THE FOLLOWING ORDER. BY DOING THIS, YOU WILL
BETTER UNDERSTAND THE IMPACT EACH INDIVIDUAL ACCESSORY HAS ON THE FUNCTION
OF YOUR TELESCOPE.
1) FOCUSING TUBE
TURN FOCUSING WHEELS TOWARD THE
TELESCOPE UNTIL IT WILL NOT GO FURTHER.
TO FOCUS BEGIN TO TURN THE FOCUSING
KNOBS TOWARD YOUR BODY, SLOWLY, UNTIL
THE IMAGE IS CLEAR. NOTE: YOU MUST HAVE
AN EYEPIECE AND DIAGONAL INSERTED IN
ORDER TO VIEW IMAGE.
2) DIAGONAL MIRROR
INSERT THE DIAGONAL MIRROR INTO THE
FOCUSING HOUSING.
GETTING THE MOST FROM YOUR TELESCOPE
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 THE 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.
3) EYEPIECE INSERTION
AFTER THE DIAGONAL IS INSERTED, PLACE
THE EYEPIECE (20MM) INTO THE DIAGONAL
MIRROR. THE LOWER THE NUMBER ON THE
EYEPIECE, THE HIGHER THE POWER YOUR
TELESCOPE WILL BE USING. PLUS, YOU
DECREASE THE FIELD OF VIEW AND THE
BRIGHTNESS OF YOUR IMAGE. WHEN USING
EYEPIECES, WE SUGGEST ALWAYS STARTING
WITH THE LOWEST POWER AND THEN GOING
UP.
