cassini C-872EFS User manual

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 ERECT IMAGE PRISM POSITIONED IN THE FOCUS HOUSING, THE IMAGE YOU
SEE WILL ALWAYS BE RIGHT SIDE UP. AND CORRECTED FROM LEFT TO RIGHT.
WE RECOMMEND YOU BEGIN WITH THE LOWEST POWER EYEPIECE (25MM). WHEN USING
THE HIGHEST POWER EYEPIECE (10MM), YOUR POWER WILL BE HIGHER, BUT THE IMAGE
WILL APPEAR DARKER; THIS IS DUE TO THE BASIC PHYSICAL PROPERTIES OF THE TELE-
SCOPE. 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.

CASSINI C-872EFS
OPERATING INSTRUCTIONS

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.
USE LOW POWER TO TAKE ADVANTAGE OF THE WIDER FIELD OF VIEW AND BRIGHTER
IMAGE. RESERVE YOUR HIGH POWERS FOR THE NIGHTS WHEN THE VIEWING
CONDITIONS ALLOW FOR DETAILED OBSERVATIONS.

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
3. EYEPIECE INSERTION -
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.
CLUTCH KNOB MUST BE LOOSE IN ORDER
TO FOCUS WITH LEFT FOCUSING KNOB.
DO NOT TRY TO FOCUS WITH CLUTCH KNOB TIGHT.
(FOR MANUAL FOCUSING ONLY.)
TIGHTEN CLUTCH KNOB WHEN USING
THE WIRELESS HANDBOX TO FOCUS."

CAUTION:
4. BARLOW LENS
THE BARLOW LENS IS USED TO ACHIEVE
THE MAXIMUM POWER FROM YOUR
TELESCOPE. FIRST, REMOVE THE DIAGONAL
PRISM 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.
EYEPIECE POWER POWER W/3X BARLOW
25MM 32X 96X
10MM PLöSSL 80X 240X
AFTER THE DIAGONAL IS INSERTED, PLACE
THE EYEPIECE (25MM) INTO THE DIAGONAL
PRISM. 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.
2. DIAGONAL PRISM
INSERT THE DIAGONAL PRISM INTO THE
FOCUSING HOUSING.

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
