The principle of Xinda Xiaohei

Cinda Xiaohei is an astronomical telescope.

First, make sure the target is the moon. Second, install the eyepiece correctly, that is to say, the eyepiece of 1.25_ does not use telescopic tube, otherwise it will not focus. Third, focusing: Turn the two circular focusing wheels on the focusing base, and the eyepiece will expand and contract with the focusing cylinder until the image is clear. Fourth, if it is still unclear, it is necessary to check whether the optical axis of the telescope is crooked. You can aim the telescope at a bright star, and then use a magnification of about 200 to make the telescope slightly out of focus, that is, out of focus, so that the image of the star will become a ring. If the inside and outside of this ring are not concentric, it means that the optical axis is crooked. The worse the concentricity, the more the optical axis deviates.

Cinda Xiaohei can directly observe the moon, Saturn and Jupiter, and can clearly see the stripes on the surface of Saturn's rings and Jupiter. If you take pictures, you can take pictures of the nebula M42, roses, horseheads and so on. As long as it is properly debugged, it can compete with tens of thousands of equipment, so it is the king of cost performance. Personally, I have a photographic version +EQ3D steel feet+double heels, which I bought in an official store in JD.COM and have maintained several times. After-sales is very convenient and professional.
