THIS TELESCOPE HAS BEEN PRODUCED TO PRECISE SPECIFICATIONS.
PRIOR TO USING YOUR NEW GALILEO 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. IN ASTRONOMICAL VIEWING,
THERE IS NO UP OR DOWN, NO RIGHT OR LEFT.
WE RECOMMEND YOU BEGIN WITH THE LOWEST POWER EYEPIECE, 25MM 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.

1. FOCUSING TUBE - TURN FOCUSING KNOBS
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. PLEASE READ
FURTHER.
2. EYEPIECE INSERTION - INSERT AN EYEPIECE
INTO THE 1.25" ADAPTER THAT IS IN 2"
FOCUSING TUBE. WE SUGGEST YOU ALWAYS
BEGIN WITH THE LOWEST POWER EYEPIECE
(25MM). REMEMBER THE LOWER THE NUMBER
ON THE EYEPIECE, THE HIGHER THE POWER
OUR TELESCOPE WILL BE USING. ALSO AS
YOU INCREASE YOUR POWER YOU WILL
DECREASE THE FIELD OF VIEW AND THE
BRIGHTNESS OF YOUR TELESCOPE.
3. BARLOW LENS - THE BARLOW LENS IS REQUIRED
TO ACHIEVE THE MAXIMUM POWER FROM
YOUR TELESCOPE. INSERT THE BARLOW
DIRECTLY INTO THE FOCUSING HOUSING
INSERT AN EYEPIECE DIRECTLY 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.
1.25" ADAPTER
THIS WILL GIVE YOU THE WIDEST FIELD
OF VIEW AND BRIGHTEST IMAGE
(25MM EYEPIECE)
2"" FOCUSER

TO MOUNT:
1) REMOVE ELECTRONIC RED EOT 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 ELECTRONIC FINDER IS NOT PRE-SET AT FACTORY. THE FOLLOWING RED EOT
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 B ATTERY 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
7) IF THE OBJECT IN THE FINDER IS NOT THE OBJECT YOU SEE THROUGH THE RED EOT
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.

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.
