Features:

– Model: Astronomical telescope
– Material: ABS acrylic + aluminum alloy + optical glass
– Color: Yellow+Black+Silver
– Weight: 2kg Package Weight
– Aperture: 70mm (2.4 inch)
– Focal Length: 300mm
– Aluminum Tripod : The most highest 120cm
– Eyepiece: H6mm, H20mm
– 3X the Barlow lens
– 1.5X erecting eyepiece

Note: This maximum magnification: 150X (lens focal length / eyepiece focal length x Barlow multiplier = maximum magnification)

About Multiples:

– Equipped with eyepiece: H6mm, H20mm, multiples are 300/6 = 50X, 300/20 = 15X, ( F12mm=30X)
– If choose 3X Barlow lens together, multiples are 50 x 3 = 150X, 15 x 3 = 45X, 30x 3 = 90X
– Plus 1.5X the positive lens again, multiples are 50 x 1.5 = 75X, 15 x 1.5 = 22.5X, 30X 1.5 =45X

The formula:

– Objective lens focal length / eyepiece focal length x Barlow multiplier = maximum magnification
– Objective lens focal length / eyepiece focal length = magnification

Installation:

Install tripod first, and then attached eyepiece (H20mm or H6mm), moon mirror (can be installed or not, it is recommended to install when there is strong light)
