INTRODUCTION Before you begin your visual journey, 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 AstroFinder Model 60 altazimuth refracting telescope. Designed for both astronomical and terrestrial observing, the AstroFinder Model 60 will be your companion in exploring a universe of celestial and earthly objects. STANDARD EQUIPMENT (Refer

10. Insert the diagonal mirror (13, Fig. 1) into the focuser drawtube (15, Fig. 1) and the H 25mm eyepiece (1, Fig. 1) into the diagonal mirror. Tighten the respective thumbscrews to a firm feel. 11. 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 a

as magnification is increased, back down to a lower power; The atmosphere is not steady enough to support higher powers. Note: Changing eyepieces changes power. 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 cente

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 12.5mm eyepiece, the resulting power will be: Power = 700mm ÷ 12.5mm = 56X. The purpose of a Barlow lens is to increase the magnification possible with a given eyepiece. The 3x Barlow supplied with this telescope will triple the normal eyepiece power. For example, the 25mm (28X) eyepiece, when used in conjunction with the 3x Barlow lens, yields 84X. The 12.5mm
