About GEERTOP Portable Telescope For Kids Astronomy
It is a high-powered telescope, with good performance observation of celestial bodies, suitable for entry-level amateur astronomers and children. Different magnification eyepieces can make you free with observed at different distances and sizes objects . And the telescope as the viewing mirror, can be upright image fully. As long as you have enough imagination, there will be more interesting and practical usefulness. WHICH MAGNIFICATION?- SELECTING THE CORRECT EYEPIECE The optimum magnification depends on what you are looking at. As a rule of thumb, the best image results from using a magnification, which is not more than 1.5X - 2.0X the diameter of the objective lens. For observation of moss heavenly bodies, a magnification of 75X - 100X can be achieved with a 50mm objective lens. A lower magnification should be used for the observation of the stars. This provides a wider field of view and simplifies aiming the telescope at the desired object. The maximum magnification should be used only for particularly clear objects such as the moon, which is relatively close to the Earth and very bright, permitting good resolution of details at high magnification. ERECTING EYEPIECE The 1.5X Erecting Eyepiece not only increases the magnification of telescope but also correct the direction of the image. For example, a telescope, which has a magnification of 60X, will have a magnification of 90X when a 1.5X Erecting Eyepiece is used. Moreover, when the telescope is used to view landscope, the erecting eyepiece can straighten out the image.
