YOUR FIRST VIEWS Until you become familiar with your telescope it is best to pick easy targets for our first views of out celestial surroundings The easiest and most interesting of dt is the moon The moon is best viewed at low power and when it is less than full Because of its iroximity to Earth its angular speed is quite fast 15 arc minutes per minute of ime or 1 2 its diameter per minute Magnification provided by the telescope not inly makes the image larger it also has the effect of increasing apparent speed naking tracking more difficult The brightness of the full moon tends to flatten some surface details and hide oth ts Best viewing is when it is waxing or waning The planets Venus Mars Jupiter and Saturn are all easy targets Venus is exceeded in brightness only by the sun and moon It is best viewed at wilight or just before dawn Look for Venus on the horizon it may be seen as a isc or as a thin crescent Mars appears as a reddish orange disc Some surface details may be seen when is closest to earth Jupiter the largest of the known planets in our solar system is an interesting sub act The great red spot is easily seen although in small telescopes it appears more lue grey than red Equally easy to see is the equatorial belt Ht also appears blue rey Four of Jupiter s moons known as the Galilean moons are seen as tiny specs of ght laying on either side of this giant planet Saturn appearing dull yellow

5. l observer The magnifying power of telescopes has no apparent effect on them no detail can be observed no visual information is revealed However to the experienced observer there are hundreds of interesting stars or groups of stars which provide a lifetime of rewarding study An example of one such star is Betelgeuse the light orange star marking one shoulder of Orion it is one of the largest know stars with a diameter 400 times our own sun Earth s orbit could easily fit inside Betelgeuse One of the most interesting features of this young star is that it periodically expands and contracts Sirius the brightest star in the night sky is actually 27 times brighter than the sun In itself Sirius is of no particular interest however because of its companion star the Pup a binary system is formed Sirius and the Pup orbit about a common center of gravity About 1 10 000 as bright as Sirius the Pup is far denser On Earth one cubic inch of the Pup s material would weight one ton The estimated mass of the Pup is 250 000 time greater than the Earth As dense as the Pup is it does not hold the record The densest of the known stars is known as AC 70 8247 A tablespoon of its substance would weigh 720 tons On the other hand the largest known star Epsilon Auringne B is 100 million times less dense than water If it were here on earth it would have to be tied down to keep it from floating away if you wish to learn more about a
