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 .
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 . ,

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 ,

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.
