With a horizontal telescope tube, this device deflects the light upwards so that you can comfortably observe by looking downwards into the eyepiece.
Eyepiece: An eyepiece is a system made for your eye and comprised of one or more lenses. In an eyepiece, the clear image that is generated in the focal point of a lens is captured and magnified still more. Magnification: The magnification corresponds to the difference between observation with the naked eye and observation through a magnifying device like a telescope.
Terrestrial Images Possible Objects for Observation: f=26 mm f=9.7 mm Terrestrial objects Take note of the examples below, including Mount Rushmore and the golf course. Start with the 26 mm eyepiece and focus until the image is clear. After mastering the 26 mm eyepiece, switch to the 9.7 mm eyepiece and practice scanning and focusing until the image is clear. Choose several terrestrial objects to practice focusing on, but never point your telescope at or near the sun, or you risk blindness.
Troubleshooting Guide: No picture Remove dust protection cap and sun-shield from the objective opening. Blurred picture Adjust focus using focus ring. No focus possible Wait for temperature to balance out. Bad quality Never observe through a glass s urface such as a window.
