INTRODUCTION
THIS TELESCOPE HAS BEEN 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.
USE THE TELESCOPE FOR TERRESTRIAL (LAND) VIEWING BEFORE ATTEMPTING TO VIEW
ASTRONOMICAL OBJECTS. THIS WILL FAMILIARIZE YOU WITH HOW POWERFUL EACH
EYEPIECE WILL BE, AS WELL AS INTRODUCE YOU TO THE FUNCTIONS OF YOUR
ACCESSORY LENSES.
THE IMAGE YOU SEE WILL BE UPSIDE DOWN AND BACKWARD. THIS IS DUE TO THE
FACT THAT YOUR TELESCOPE IS AN ASTRONOMICAL TELESCOPE AND HAS BEEN
MANUFACTURED FOR ASTRONOMICAL OBSERVATIONS.
WE RECOMMEND YOU BEGIN WITH THE LOWEST POWER EYEPIECE (20MM) WHEN USING
YOUR TELESCOPE. WHEN USING THE HIGHEST POWER EYEPIECE (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 POWER. 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.

HOW TO USE EYEPIECES & ACCESSORIES
1. FOCUSING TUBE - TURN FOCUSING KNOB (LEFT SIDE)
TOWARD THE TELESCOPE UNTIL IT WILL GO
NO FURTHER. TO FOCUS MANUALLY BEGIN
TO TURN THE FOCUSING KNOB TOWARD
YOUR BODY, SLOWLY, UNTIL THE IMAGE IS
CLEAR.
NOTE: YOU MUST HAVE AN EYEPIECE INSER-
TED IN ORDER TO VIEW IMAGE. RIGHT SIDE
IS CLUTCH KNOB
2. EYEPIECE INSERTION - INSERT AN EYEPIECE
INTO THE RECEIVING END OF THE FOCUSING
TUBE. WE SUGGEST YOU ALWAYS BEGIN
WITH THE LOWEST POWER EYEPIECE (20MM).
THE LOWER THE NUMBER ON THE EYEPIECE,
THE HIGHER THE POWER YOUR TELESCOPE
WILL BE USING. ALSO AS YOU INCREASE
YOUR POWER YOU WILL DECREASE THE
FIELD OF VIEW AND THE BRIGHTNESS OF
YOUR TELESCOPE. WE SUGGEST YOU
ALWAYS USE THE LOWEST POWER REQUIRED
TO VIEW YOUR SUBJECT. PROPER PLACEMENT
OF THE EYEPIECES AND ACCESSORIES ARE
IMPORTANT IN ORDER TO ASSURE EASY
OPERATIONS AND CLEAR VIEWING.
3. BARLOW LENS - THE BARLOW LENS IS USED TO
ACHIEVE THE MAXIMUM POWER FROM YOUR
TELESCOPE. INSERT THE BARLOW DIRECTLY
INTO THE FOCUSING HOUSING, THEN INSERT
AN EYEPIECE INTO THE RECEIVING END OF
YOUR BARLOW LENS. REMEMBER YOU WILL
HAVE TO READJUST YOUR FOCUSING DUE
TO THE FACT THAT YOU HAVE INCREASED
THE POWER OF YOUR TELESCOPE.
PLEASE CONSIDER USING YOUR ACCESSORIES IN THE FOLLOWING ORDER. BY DOING THIS
YOU WILL BETTER UNDERSTAND THE IMPACT EACH INDIVIDUAL ACCESSORY HAS ON THE
FUNCTION OF YOUR TELESCOPE.

4. 1.5X ERECTING LENS - IF YOU ARE CURRENTLY
USING THE BARLOW LENS, REMOVE IT
BEFORE INSERTING THE ERECTING LENS.
INSERT THE ERECTING LENS DIRECTLY INTO
THE FOCUSING TUBE, THEN PLACE THE
EYEPIECE INTO THE RECEIVING END OF THE
ERECTING LENS.

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 S AVER L OCATED B ENEATH F RONT O F F INDER (B E S URE.
TO SAVE AND REPLACE THE BATTERY SAVER WHEN NOT IN USE.)
5) TURN FINDER ON B Y S LIDING O N/OFF S WITCH F ORWARD. O N/OFF S W ITCH IS LO CATED
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.
MARS-EYE ELECTRONIC FINDER
MOUNTING & ALIGNMENT

AS STATED EARLIER IN THE INSTRUCTIONS, THE BARLOW LENS INCREASES THE POWER
OF 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.
USING THE BARLOW LENS
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.
