Max Multiples:675 times — Be able to See the Annular Island on the Moon Clearly!
About Multiples:
– Equipped with eyepiece: SR4mm,H12.5mm, H20mm, multiples are 900/4 = 225X, 900/12.5 = 72X,900/20=45X
– If choose 3X Barlow lens together, multiples are 225 x 3 = 675X, 72 x 3 = 216X,45 x 3 = 135X
– Plus 1.5X the positive lens again, multiples are 225 x 1.5 = 337X, 72 x 1.5 = 108X,45 x 1.5 = 67X
The Formula:
– Objective lens focal length / eyepiece focal length x Barlow multiplier = maximum magnification
– Objective lens focal length / eyepiece focal length = magnification
About Configuration:
– Moon Filter: Because there is a lot of reflected light interfering our observation of full moon, so we can use the moon filter to avoid the interference, and then the moon’s surface will be seen more clearly.
– Please screw the moon filter into the threaded of eyepiece lens’ lower part, and then connect the eyepiece lens with zenith lens.
Note:
1.Night Vision Function Means The Telescope Works Better in Weak Light Surroundings than Ordinary Telescopes, But It Does not Work in Total Darkness. If You Mind this, Please Do Not Buy.
2. Basic Waterproof Function Means the Telescope can Cope with Small Rain Drops or Water Drips but It will Get Spoiled under Massive Water Conditions.
Caution:Never Try to Observe the Sun Directly thought the Telescope,It will Hurt Your Eyes Seriously!!
