CASSIOPEIA-THE QUEEN Locate Polaris (see page 70 for how to do this) then continue this imaginary line on for the same distance you’ve already come from the Plough, take a slight bend to the right, and you’ll arrive at the ‘W’ asterism in the constellation of Cassiopeia. GEMINI-THE TWINS 7R!"QG!&DVWRU!DQG!QHDUE\!3ROOX[#!WKH!PDLQ!VWDUV!RI!*HPLQL#!VWDUW!IURP! the Plough star Megrez. Draw an imaginary line to Merak, diagonally opposite it, and keep going. Almost halfway to your target look out for the two stars that form the front paws of Ursa Major. LEO-THE LION To locate Leo start from Megrez, this time imagining a line through Phecda, the star below it in the Plough. Continue on this line and you’ll reach Regulus, the brightest star in Leo. The Lion’s head is a hook-shaped asterism called the Sickle, with Regulus at its base. AURIGA-THE…

spring target m5 globular cluster in serpens caput

NAKED EYE What you see just by looking up At magnitude +5.7, globular cluster M5 is about as faint as you can see with the naked eye. If you have very dark and clear skies it is possible to see it, resembling a very faint star right on the edge of sight. From the UK, M5 never really gets very high in the sky, only reaching a maximum altitude of 38! when due south. This means that some of its light is lost to the atmosphere, which makes spotting it just that little bit harder. The easiest way to track it down is to look for the two similarly bright stars in Libra that lie to the east of bright Spica in Virgo. Imagine the line they make as the bottom-right spoke…

your first night stargazing

IWSV"\RXU"#UVW"QLJKW" outside, you’ve found a nice, dark spot and you’re gazing up at a sky peppered with pinpricks of light – so where do you begin? Starting out on your astronomical adventure can be as mystifying as it is exciting, but assuming you live in the northern hemisphere at a mid-to-high ODWLWXGH$"\RXU"#UVW"JRDO"LV"WR" #QG"WKH"JURXS"RI"VHYHQ"VWDUV" known as the Plough. The Plough is an asterism – a pattern of stars – within the constellation of Ursa Major (the Great Bear). It happens to look like a saucepan and it marks the bear’s tail and back. The reason we’re starting at the Plough is not only because this asterism is EULJKW"DQG"HDV\"WR"#QG$"EXW" because we have to take into account the rotation of the Earth. Just as the Sun appears to rise, move over the sky and set,…
