Easy Astronomy by Lawrence

Summer funda.......


The purpose of this is to provide beginners basic knowledge of skywatching without a telescope or binoculars. The best way to start astronomy as a hobby is to read and watch the sky without technical equipment. In this very first article of this series we will start skywatching from constellations that are easy to locate. Those are Big Dipper(Saptarishi), Orion (Mriga) .
Most people have recognized and are able to locate Big Dipper in nightsky, even though they would not be interested in astronomy. The Big Dipper is probably the best known constellation. It has bright stars and it is very easy to locate because it looks like a plough. The Big Dipper, formed by seven stars, is probably the best constellation to start observing the nightsky.
Start by locating Big Dipper as I have described in my earlier article. As soon as you have discovered the Big Dipper, you can easily find also the polar star, Polaris, which is almost in the center of the sky in northern hemisphere. Use the first star of Big Dipper, Alkaid, and Polaris to position . “Draw a line” from Big Dipper’s first star, Alkaid, to polar star(Dhruv star)
