It is a powerful telescope, with good observation performance of air items. Different magnification eyepieces can adust focus on different distances and sizes objects, more convenient observation. And you will see right images through the viewing of the telescope glass.
WHICH MAGNIFICATION?- SELECTING THE CORRECT EYEPIECE
The optimum magnification depends on what you want to observe. The magnification lens should be no more than 1.5X - 2.0X the diameter of the objective lens. To observe moss heavenly bodies, use a magnification lens of 75X - 100X with a 50mm objective lens.
A lower magnification lens should be used for gazing stars. It provides a wider field of view and simplifies aiming at the desired object.
The maximum magnification lens only used 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.
The 1.5X Erecting Eyepiece can 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 if you use a 1.5X Erecting Eyepiece.
Moreover, when the telescope is used to observe landscape, the erecting eyepiece can straighten out the image.
