The function of the built-in compass of the telescope and how to use it

How does the telescope distinguish the direction-compass series telescope

For outdoor exploration or sailing, telescopes need to be used frequently. To ensure safety, it is important to have a telescope for navigation and observation in any environment. Therefore, Yuanjin Optics has launched a series of telescopes with a built-in compass, which also have the functions of viewing and distinguishing directions.

Use of compass

When you use the telescope to observe, you can easily read the azimuth angle of the target through the right eyepiece. Each division of the compass is 1°. When the observed target is true north of you, the compass displays 360° and follows a clockwise relationship, that is, 90° indicates that the target is directly east of you, and 180° indicates that it is true south. , 270° means it is in the west.

In order to make the compass indication more accurate, magnetic materials (such as artillery, tanks, high-voltage lines, substations, magnetite, electromagnetic devices, etc.) should be avoided as much as possible when using the compass to measure the azimuth, so as to avoid observation errors and reduced compass sensitivity. Keep the telescope level and the pitch angle cannot exceed plus or minus 15° to maintain the relative verticality of the geomagnetic line and the magnetic needle, so that the observed target is located at the center of the division to reduce measurement errors.
