at certain timesyou will be able


The largest cheap hermes outlet planet in the solar system isvery well placed this time of year  forobservations.  Not only will you be ableto pick out detail in the cloud belts of this gas giant but at certain timesyou will be able to see the Great Red Spot, a hurricane larger than Earth thathas been raging for centuries. Look for the four Galilean moons either side ofthe planet to and notice how they change their position night after night.  Medium to high magnification.

Obvious perhaps, but choosing the righttime to look at the moon is crucial to what you will see.  The worst time to study the Moon is when itis full because very few shadows are being cast except around the very edge orlimb.  Shadows are great at enhancingsurface detail so avoid a full moon. I am often contacted by people for adviceon buying telescopes, particularly as gifts around Christmas. So if you are oneof those lucky people with a shiny new telescope (or just want to have a funnight observing) then your eyes are about to be opened to a wonderfulUniverse.  But what can you point your'scope at? Deciding what to look for can be tricky, so here are my Hermes Garden Party top tenobjects for beginners.

This beauty is a morning object but wellworth getting up early for.  With amagnification from around 25x and above you will be able to detect the stunningring system the planet is famous for.  Ifthe atmosphere is steady and you use a high enough magnification you can evensee gaps in the rings such as the Cassini Division.

Perhaps the best of all the nearest majorgalaxies is the Andromeda Galaxy which lies a staggering 2.3 millionlight-years away.  As its name suggestsit is found in the constellation Andromeda on its western side, just off thenorth east corner of the Square of Pegasus. Keep magnification low for this object and larger aperture telescopeswill reveal more detail.  See if you canspot the satellite galaxies M32 and M110. Low magnification.

be seen asbeautiful golden yellow and blue stars. Larger telescopes and good viewingconditions will reveal the blue star is actually another binary star.  Medium to high magnification required and alarge aperture telescope to reveal third star. Medium sized telescopes and modestmagnifications will show the stars inside the nebula called the Trapezium.  Don't expect to see it in all its colourfulglory like the pictures.  Cameras aremore sensitive to color in low light levels than the human eye so it will chanel wallet womenonlyappear as grey/green.  Low to mediummagnifications.
