cassini CS-102 User manual

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.
FOR TERRESTRIAL VIEWING WE HAVE ADDED AN ERECTING LENS SO THAT WHEN YOU
VIEW OBJECTS ON THE EARTH YOUR IMAGE WILL BE RIGHT SIDE UP.
WE RECOMMEND YOU BEGIN WITH THE LOWEST POWER EYEPIECE(20MM) WHEN USING
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.
NOTE: SPECIFICATIONS ARE SUBJECT TO CHANGE WITHOUT NOTICE.

(MOST POWERFUL - LEAST LIGHT )
20MM EYEPIECE = 55X

HOW TO USE EYEPIECES & ACCESSORIES
1. FOCUSING TUBE - TURN FOCUSING WHEELS
TOWARD THE TELESCOPE UNTIL IT WILL GO
NO FURTHER. TO FOCUS BEGIN TO TURN THE
FOCUSING KNOBS TOWARD YOUR BODY,
SLOWLY, UNTIL THE IMAGE IS CLEAR. NOTE:
YOU MUST HAVE AN EYEPIECE INSERTED IN
ORDER TO VIEW IMAGE.
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 INCREASEYOUR
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.
3. 1.5X ERECTING LENS - INSERT THE ERECTING
LENS DIRECTLY INTO THE FOCUSING TUBE.
THEN PLACE THE EYEPIECE INTO THE RECEIVING
END OF THE ERECTING LENS
PROPER PLACEMENT OF THE EYEPIECES AND ACCESSORIES ARE IMPORTANT IN ORDER
TO ASSURE EASY OPERATIONS AND CLEAR VIEWING.
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.

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 WHAT YOU SEE THROUGH THE MAIN
TELESCOPE TUBE, ADJUSTMENT IS REQUIRED.
8) TO MOVE THE RED DOT UP AND DOWN, TURN THE ELEVATION SCREW LOCATED ON THE
REAR BOTTOM OF THE FINDER TO HEIGHT REQUIRED.
9) TO MOVE THE RED DOT LEFT AND RIGHT, 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

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 POWER FOR THOSE NIGHTS WHEN VIEWING
CONDITIONS ALLOW FOR DETAILED OBSERVATIONS.
