focused image. Reflecting telescope - an optical design in which light is reflected off of a curved mirror that converges the light into a small disk that is then magnified using an eyepiece. First, you need to take the time to familiarize yourself with the parts of your PowerSeeker telescope - Celestron PowerSeeker 127EQ Telescope | PowerSeeker 127 EQ Manual - Page 3

THE POWERSEEKER 127 Reflector The PowerSeeker is a Newtonian reflecting telescope that comes on an equatorial mount. This section instructs you on the proper assembly and use of your PowerSeeker telescope, which is shipped in one box, containing all the parts you need to assemble it.

on the side of the focuser. 3. Your telescope also comes with a 3x Barlow lens which triples the magnifying power of each eyepiece (see Magnification section of the manual). To use the barlow lens, insert the barlow lens directly into the focuser. Then start by using the low power eyepiece such - Celestron PowerSeeker 127EQ Telescope | PowerSeeker 127 EQ Manual - Page 6
light. The nature of the optical design determines how the light is focused. Some telescopes, known as refractors, use lenses. Other telescopes, known as reflectors, use mirrors. A Newtonian reflector uses a single concave mirror as its primary. Light enters the tube traveling to the mirror at - Celestron PowerSeeker 127EQ Telescope | PowerSeeker 127 EQ Manual - Page 7

The Celestial Coordinate System To help find objects in the sky, astronomers use a celestial coordinate system that is similar to our geographical coordinate system here on Earth. The celestial coordinate system has poles, lines of longitude and latitude, - Celestron PowerSeeker 127EQ Telescope | PowerSeeker 127 EQ Manual - Page 9
the fine adjustment controls on the mount. Figure 9 - Equatorial Head PowerSeeker 127 Remember, while Polar aligning, do NOT move the telescope in R.A. or DEC. You do not want to move the telescope itself, but the polar axis. The telescope is used simply to see where the polar axis is pointing. 9 - Celestron PowerSeeker 127EQ Telescope | PowerSeeker 127 EQ Manual - Page 10
the northern hemisphere all stars move around the north celestial pole. When the telescope's polar axis is pointed at the celestial pole, it is parallel to sky, it may be difficult to locate from urban areas. If this is the case, use the two end stars in the bowl of the Big Dipper (the pointer stars - Celestron PowerSeeker 127EQ Telescope | PowerSeeker 127 EQ Manual - Page 11
once you have found the desired object. Magnification The magnification (or power) of a telescope varies depending upon the focal length of the eyepiece being used and the focal length of the telescope. The PowerSeeker 127 telescope has a focal length of 1000mm and comes with a 20mm 1¼" eyepiece. To - Celestron PowerSeeker 127EQ Telescope | PowerSeeker 127 EQ Manual - Page 12
