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.
