User manual CELESTRON POWERSEEKER 50AZ

[. . . ] The PowerSeeker Series of telescopes come in several different models and this manual covers four models mounted on Alt-Az Mounts ((an altazimuth is the simplest type of mount with two motions ­ altitude (up & down) and azimuth (side-to-side)) --- 50mm refractor, 60mm refractor, 70mm refractor, and a 76mm Newtonian. the PowerSeeker Series is made of the highest quality materials to ensure stability and durability. All this adds up to a telescope that gives you a lifetime of pleasure with a minimal amount of maintenance. These telescopes were designed for the First Time Buyer offering exceptional value. [. . . ] You will be able to see the cloud belts of Jupiter and the great Red Spot (if it is visible at the time you are observing). In addition, you will also be able to see the moons of Jupiter as they orbit the giant planet. Saturn, with its beautiful rings, is easily visible at moderate power. Remember that atmospheric conditions are usually the limiting factor on how much planetary detail will be visible. So, avoid observing the planets when they are low on the horizon or when they are directly over a source of radiating heat, such as a rooftop or chimney. To increase contrast and bring out detail on the planetary surface, try using Celestron eyepiece filters. Although overlooked by many amateur astronomers, solar observation is both rewarding and fun. However, because the Sun is so bright, special precautions must be taken when observing our star so as not to damage your eyes or your telescope. For safe solar viewing, use a proper solar filter that reduces the intensity of the Sun's light, making it safe to view. With a filter you can see sunspots as they move across the solar disk and faculae, which are bright patches seen near the Sun's edge. The best time to observe the Sun is in the early morning or late afternoon when the air is cooler. To center the Sun without looking into the eyepiece, watch the shadow of the telescope tube until it forms a circular shadow. Deep-sky objects are simply those objects outside the boundaries of our solar system. They include star clusters, planetary nebulae, diffuse nebulae, double stars and other galaxies outside our own Milky Way. Visually, they are too faint to reveal any of the color seen in long exposure photographs. And, because of their low surface brightness, they should be observed from a dark-sky location. Light pollution around large urban areas washes out most nebulae making them difficult, if not impossible, to observe. Light Pollution Reduction filters help reduce the background sky brightness, thus increasing contrast. Star hopping is done by using bright stars to "guide" you to an object. For successful star hopping, it is helpful to know the field of view of you telescope. If you're using the standard 20 mm eyepiece with the PowerSeeker telescope, your field of view is approximately 1. If you know an object is 3º away from your present location, then you just need to move about two fields of view. [. . . ] Collimation adjustments are best made while viewing the star's position in the field of view and turning the adjustment screws simultaneously. It may be helpful to have two people working together: one viewing and instructing which screws to turn and by how much, and the other performing the adjustments. IMPORTANT: After making the first, or each adjustment, it is necessary to reaim the telescope tube to re-center the star again in the center of the field of view. The star image can then be judged for symmetry by going just inside and outside of exact focus and noting the star's pattern. [. . . ]
