INTRODUCTION Before you begin, we urge you to take a few minutes to completely read this manual so that you can get the best use of the equipment. This manual details the set-up, operation, specifications and optional accessories of the Telestar 60-AZ-A altazimuth refracting telescope. Designed for both astronomical and terrestrial observing, the Telestar 60-AZ-A will be your companion in exploring a universe of celestial and earthly objects. STANDARD EQUIPMENT (Refer to Fig. 1) • Complete optic

11. Insert the diagonal mirror (13, Fig. 1) into the focuser drawtube (15, Fig. 1) and the MA 25mm eyepiece (1, Fig. 1) into the diagonal mirror. Tighten the respective thumbscrews to a firm feel. 12. The telescope is now completely assembled. To move the telescope and point it from one object to another, first slightly loosen one of the chrome-lock (star-shaped) knobs (5, Fig. 1) which serve as a vertical lock, then loosen the azimuth (horizontal) lock (6, Fig. 1). Also, slightly loosen the alt

3. If you are observing an astronomical object (the Moon, a planet, star, etc.) you will notice that the object will begin to move slowly through the telescopic field of view. This movement is caused by the rotation of the Earth and makes an object appear to be moving in the telescope’s field of view. To keep astronomical objects centered in the field, simply move the telescope on one or both of its axes (vertical and/or horizontal) as appropriate. At higher powers, astronomical objects will s

For example, if you are using a 25mm eyepiece, the resulting power will be: Power = 700mm ÷ 25mm = 28X. For example, if you are using a 9mm eyepiece, the resulting power will be: Power = 700mm ÷ 9mm = 78X. The purpose of a Barlow lens is to increase the magnification possible with a given eyepiece. The 2x Barlow supplied with this telescope will double the normal eyepiece power. For example, the 25mm (28X) eyepiece, when used in conjunction with the 2x Barlow lens, yields 56X. The 9mm (78X) eyep
