COMET 70mm Refractive Terrestrial and Astronomical Telescope (300mm) with Tripod for Entry-level Amateur Astronomers and Children to Explore Land & Sky SilverThe telescope have an Optical glass lens, metal optical tube, aluminum table top tripod, 3X Barlow lens & 3 eyepieces. The telescope is very convenient and simple to assembly. The telescope is suitable for entry-level amateur astronomers and children to explore land & sky! 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 landscape, the erecting eyepiece can straighten out the image. Remove the angle prism and insert 1.5X Erecting Eyepiece between the eyepiece and the telescope.Astronomical Use:1. Always start viewing with your 20mm eyepiece. This is your low power eyepiece and its wide viewing field will make it easier to locate objects.2. Once you have located an object and the view is clear you may wish to change to the high power eyepiece. You will notice that your object looks bigger, but it not as bright as seen with the 20mm eyepiece. This normal. If the viewing conditions are not good the high power image may not appear sharp or stable. If this happens, switch back to the 20mm eyepiece and try the high power eyepiece another night. You can also achieve higher power by inserting the 3X Barlow lens between the telescope and either eyepiece. This triples the available power.Terrestrial Use:1. 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.2. To achieve correct orientation you will use the Image Erector that is supplied with your telescope.1) Remove the diagonal from your telescope.2) Insert the Image Erector into the focuser. Then insert the 20mm eyepiece. When you look through the telescope you will find that the image you see is right-side up and properly oriented.3) For more magnification remove the 20mm Eyepiece and replace it with the high power one.3. The 3X Barlow lens and the Image Erector. To use either of these accessories remove the eyepiece, insert the desired accessory into the telescope’s eyepiece holder, then insert the eyepiece into the open end of the accessory.Specification:1.
