Features:
1. The finderscope is designed for the purpose of visual finder. The refracting telescope is attached to the main telescope to search for the object to be observed.2. Aluminum tripod, light, steady, resistant.3. Multi-position rotation, visual diversification, far-sightedness, starry sky more clear and convenient, stable and firm.4. Detachable finderscope, lens cover, eyepiece, refractor, etc., easy to familiar with the principle of the telescope, more convenient storage and carrying.5. Suitable for entry-level amateur astronomers and children.Configuration: focal length is 300mm, aperture is 70mm, with 2 eyepieces: H6 (for daytime viewing) and H20 (night to see the moon), with 3 times the Barov mirror and 1.5 times positive mirror and moon mirror. Moon Mirror: Because there is a lot of reflected light interference when observing the full moon, using a moon mirror can eliminate these interferences and make the lunar surface look more clearly. When using, please screw the moon mirror into the thread on the lower part of the eyepiece, and then connect the eyepiece with the Zenith mirror.Multiple: Eyepieces: H6mm, H20mm multiples: 300/6=50 times, 300/20=15 times. If you choose 3 times Balov mirrors, then the multiple 50X3 = 150 times, 15X3 = 45 times; plus 1.5 times the positive mirror, imaging is a positive image, the multiples are: 50X1.5 = 75 times, 15X1 .5 = 22.5 times. That is: the minimum magnification: 15 times, the maximum magnification: 150 times.Installation sequence:The tripod is first supported and then the barrel is attached. After the lens barrel is fixed, a finderscope is installed on the lens barrel (used to initially find the target object), and then the eyepiece is installed (eyepiece 2 selects 1). After finding a big goal, then adjust with different eyepieces.
