INTRODUCTION Your telescope is an excellent beginner’s instrument, and is designed to observe objects in the sky and also on land. It can be your personal window on the universe or allows you to intimately study the behavior of nesting birds on a distant hillside. The telescope is shipped with the following parts: • Optical tube • Aluminum tripod with accessory tray • Two 1.25” eyepieces: MA25mm, MA9mm • 90 degree erect image diagonal mirror • 2X Barlow • Red-dot viewfinder with bracket • Yoke-style mount The Infinity 60 optical tube has a focal length of 800mm, and its objective lens has a diameter of 60mm. The Infinity 70 optical tube has a focal length of 700mm and diameter of 70mm. The lens diameter is one of the most important pieces of information about the telescope. The size of the objective lens determines how much detail you will be able to see in your telescope. The focal length information will help later on to calculate magnification. Setting up your telescope involves these simple steps: • Setting up your tripod • Attach the accessory tray • Attach the optical tube to the mount • Attach the viewfinder • Attach the diagonal mirror and eyepiece • Align the viewfinder Study the picture on the next page and become acquainted with the parts of your telescope.
