Professional Astronomical 150 Times Zoom Telescope with Finderscope - Silver

Specifications:
• Aperture: 70mm (2.4 inch)
• Focal Length: 300mm f/4
• Oblique Mirror: 48 degrees
• Warp / Weft Machine and Aluminum Tripod
• The Most Highly: 115cm
• For: Astronomy
• Material: Optical glass
• Colour: Silver
• Size (L x W x H): 31.50 x 10.50 x 10.50 cm / 12.4 x 4.13 x 4.13 inches
• Eyepiece: H6mm, H20mm
• 3X the Barlow lens
• 1.5X positive lens
About Configuration:
• Moon Filter: Because there is a lot of reflected light interfering with our observation of the 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 eyepiece lens' lower part, and then connect the eyepiece lens with the zenith lens.
About Multiples:
• Equipped with eyepiece: H6mm, H20mm, multiples are 300/6 = 50X, 300/20 = 15X
• If choose 3X Barlow lens together, multiples are 50 x 3 = 150X, 15 x 3 = 45X
• Plus 1.5X the positive lens again, multiples are 50 x 1.5 = 75X, 15 x 1.5 = 22.5X
Installation sequence:
Put up the tripod, then attach the lens tube.
After the tube is fixed, install the finderscope (for the preliminary search of the target object), then install the eyepiece (choose one from the two).
After finding out the big goal, then debug with different eyepieces.

Note: Multiples of course are not the only ones, and it depends on the combination of factors aperture and focal length. (For example, if the window is big, the natural light is good, and the view is clear.)
When using the 3X Barlow lens, installed the Barlow lens first, and then install the eyepiece. ( When installing the Barlow lens, we need to move out the lid on the installation device of an eyepiece.)
We just can choose one eyepiece to install at the same time, and so does the Barlow lens.
