[. . . ] 1) can be tightened and the altitude slow-motion fine-adjustment control knob (16, Fig. 1) can then be used to make very smooth and accurate tracking in the vertical axis. VIEWFINDER FOCUSING AND ALIGNMENT The 5 x 24mm viewfinder (2, Fig. 1) is a low-power, wide-field sighting device that, once aligned, will allow you to point the telescope with greater precision. Note: When you look through the viewfinder, you will see a crosshair with images that will be upside-down; this is normal. To work properly, the viewfinder must first be aligned to the telescope's main optical tube. Insert the 25mm wide-field eyepiece into the diagonal mirror (13, Fig. Make sure the detail of the distant object you have chosen is in sharp focus. 1) in both the front and rear rings using the collimation screws (3, Fig. Next, looking through the viewfinder, adjust the collimation screws on the rear ring until the object centered in the telescope's main tube is likewise positioned in the center of the viewfinder's crosshairs. Now it is possible to quickly sight an object in the viewfinder first, then find that object approximately centered in the 25mm eyepiece of the telescope. If the viewfinder's infinity image is not in sharp focus, the knurled end of the eyepiece can be turned to fine tune the focus. Be sure to hold the viewfinder firmly between your fingers when making this adjustment. USING THE TELESCOPE With the telescope assembled, you are ready to begin observations. Observing land objects during the daytime is a good way to become accustomed to the operation of the telescope. At night, try observing the Moon at first (if it is visible) or a bright star. OBSERVING THE SUN, EVEN FOR THE SMALLEST FRACTION OF A SECOND, WILL RESULT IN INSTANT AND IRREVERSIBLE EYE DAMAGE, AS WELL AS PHYSICAL DAMAGE TO THE TELESCOPE ITSELF. To center an object in the main telescope, first use the aligned viewfinder to find the object you wish to observe. 1) to re-position the telescope so that the desired object can be centered in the viewfinder. When the object is centered in the viewfinder, it should then, also, be somewhere in the main telescope's field of view. Next, using the 25mm eyepiece, center the object in the main telescope's field of view, and sharply focus the image by turning the focus knob (23, Fig. The wide-field H 25mm eyepiece included as standard equipment is the best eyepiece to use for the initial finding and centering of an object. The low-power H 25mm eyepiece presents a bright, wide field of view, ideal for terrestrial and general astronomical observing of star fields, clusters of stars, nebulae, and galaxies. For lunar and planetary viewing, switch to a higher power eyepiece such as the H 12. 5mm -- if you have good viewing conditions. [. . . ] 1) causes negligible degradation of image quality and should not be considered reason to clean the lens. When lens cleaning does become necessary, use a camel hair brush or compressed air to gently remove dust. Wipe only with a soft, clean cloth, applying as little pressure as possible to avoid scratching glass surfaces. Note: Gently pull off and remove the the dew shield/lens shade (21, Fig. [. . . ]
