Save method

The optimum condition of the telescope is that the temperature is 20-25 degrees, and the temperature is below 65%. Such as placed in a large temperature difference between the local or damp place, in the telescope lens surface will fog or fine drops appear, then must be the telescope at room temperature slowly completely dry.

Maintain

Use the telescope should be light, avoid man-made accident impact the optical axis error cannot be observed. (ordinary telescopes do not have the shock function) if the telescope can not be observed, please consult a professional to avoid the removal or replacement of lenses.

clean

The telescope lens surfaces such as stained with dust or other marks, will directly influence the observed effects, then available lens cleaning cloth dipped in take a little industrial alcohol wipe the surface, due to the plating film, please avoid rough objects and fingers with direct contact with the surface of the lens.

Telescope instructions:

1 adjusting target distance

The telescope two tube distance, until the left and right as the occasion for a circular field of view.

2 focus

To turn the telescope at the center of the adjusting mechanism (hand wheel or regulation board), until the left eye can see the target so far.

Then rotate the hand wheel visibility of right eye, right eye to see the target.

The purpose of this action is to allow the telescope to adapt to poor eye sight. Remember the right eye position remains unchanged. And then observe the different distance of the target when the direct rotation of the focusing wheel on it!
