Using method.
1, Brace feet pull apart, mount the telescope tube to the yoke, and lock the mirror with the set screw.
2、Insert the reflector into the focusing cylinder and fix it with the corresponding screw.
3、Mount the eyepiece on the reflector and fix it with the corresponding screw.
4、If you wish to magnify with the 1.5X forward mirror, install it between the eyepiece and the barrel so that you can watch the celestial bodies.
5、Eyepiece
Such as: focal length of 500mm with H6mm eyepiece is 83 times the magnification, with 1.5 times forward mirror (magnifying glass) magnification of 125 times, with 3 times forward mirror (magnifying glass) magnification of 250 times.
If the focal length is 500mm with H10mm eyepiece, the magnification is 50 times, 75 times with 1.5 times forward lens (intensifier), and 150 times with 3 times forward lens (intensifier).
For example, if the focal length is 500mm with H20mm eyepiece, the magnification is 25 times, with 1.5 times forward lens (magnifying lens) the magnification is 38 times, with 3 times forward lens (magnifying lens) the magnification is 75 times.
Such as: focal length of 500mm with H25mm eyepiece is 20 times magnification, with 1.5 times forward lens (magnifying lens) magnification 30 times, with 3 times forward lens (magnifying lens) magnification 60 times.
