– 6 – 9. Attach the viewfinder bracket (7) to the telescope using the 2 thumbscrews provided. These thumbscrews are pre-threaded into the telescope at the viewfinder location. The thumbscrews fit through the 2 holes at the base of the viewfinder bracket and thread into the main optical tube. 10. Insert the diagonal mirror (5) into the focuser drawtube (25) and the 25mm eyepiece (6) into the diagonal mirror. Secure each in place with a moderate tightening of the respective thumbscrews. The tel

Right Ascension and Declination is analogous to the Earth-based coordinate system of latitude and longitude. Understanding celestial coordinates: Celestial objects are mapped according to the R.A. and Dec. coordinate system on the “celestial sphere,” the imaginary sphere on which all stars appear to be placed. +90° Dec.

– 8 – LINING UP WITH THE CELESTIAL POLE Objects in the sky appear to revolve around the celestial pole. In northern latitudes the North Star (Polaris) approximates the pole. (Actually, celestial objects are essentially “fixed,” and their apparent motion is caused by the Earth's axial rotation). During any 24 hour period, stars make one complete revolution about the pole, making concentric circles with the pole at the center. By lining up the telescope's polar axis with the North Celestial Po

The 25mm eyepiece included as standard equipment is the best eyepiece to use for the initial finding and centering of any object. The 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

– 10 – The number of fascinating objects visible through your Infinity refractor is limited only by your own motivation. Astronomical software, or a good star atlas (see “Meade Star Charts” in OPTIONAL ACCESSORIES, page 11) will assist you in locating many interesting celestial objects. These objects include: • Cloud belts across the surface of the planet Jupiter. • The 4 major satellites of Jupiter, visible in revolution about the planet, with the satellite positions changing each night. • Sa
