* About Magnification:
The magnification power of a telescope indicates how much an image is enlarged or how big and close it appears to the viewer. The focal length of the eyepiece, combined with the focal length of the telescope, determine the magnification power. To calculate the power of your telescope with any particular eyepiece, simply divide the focal length of the telescope (900mm) by the focal length of the eyepiece (indicated in “mm” on the eyepiece collar). For example, when you use the eyepiece H20mm with this telescope, the magnification will be 45X.
* Erecting eyepiece
Your telescope is a dual purpose model. It can be used for astronomy, as well as for viewing objects on land. When viewing terrestrial objects you will want objects to appear both right-side up, and correctly oriented left to right, just as you see them with your eyes. To achieve correct orientation you can use the Erecting eyepiece that is supplied with your telescope.
* Barlow lens
The Barlow lens increases the magnification factor provided by the telescope. A 3x Barlow lens will therefore triple the telescope's magnification power. Consequently it is possible to triple a 45x magnification factor to increase it to 135x using a 3x Barlow lens. The highest magnification factor Barlow lens should only be used for very bright, large objects such as the moon and the brightest planets or during nighttime observations when conditions are optimal.
NEVER aim your telescope at the sun or even close to the sun!
