As with many things, the better you understand the workings of the equipment, the more enjoyment you will get from it. This is particularly true of telescopes. So take a few moments now to become thoroughly acquainted with your new telescope. Mastering an astronomical telescope is a key to the success in astronomical observation. Installation of an eyepiece ©The magnification of your telescope is determined by the eyepiece you use. It can be computed with the following formula. Magnification =|oca| ¡-en9£ °4 Objective {mm} Focal Length of Eyepiece (mm) <2)Read the writing on the eyepiece, and you may find characters such as "K20mm", "HM12.5mm" or "LV5mm". The first letter represents the type of eyepiece design, the number that follows represents the focal length of the eyepiece. As the number gets smaller, the magnification power of the eyepiece becomes greater, thereby allowing the viewer to observe close-up detail. ¡3)Eyepieces are classified into three sizes of barrel diameter. 24.5mm, 31.7mm and 50.8mm. @To set a 24.5mm, 31.7mm or 50.8mm eyepiece, insert it in a proper 24.5mm, 31.7mm or 50.8mm eyepiece adapter and securely tighten the eyepiece setscrew. Step 3 First operation of the telescope ©Unfasten the R. A. and Decl. clamps and you can move the optical tube in a full range of motion. CAUTION : DO NOT FORCE THE OPTICAL TUBE TO MOVE WHEN THE R. A. CLAMP OR DECL. CLAMP IS FULLY ENGAGED. THIS MAY DAMAGE PR...
