On reaching the open field at East Coast Park, she was overwhelmed by the number of huge super whopper telescopes lining the muddied field.
While waiting for the sky to be dark enough, some of the enthusiasts focused on other astronomical phenomenon.
M42, the Orion Nebula, is part of a giant complex of clouds of interstellar gas and dust. Pockets of this material are collapsing to give birth to new stars...
First discovered in August 2014 by Australian amateur astronomer Terry Lovejoy using his backyard telescope, Comet C/2014 Q2, otherwise known as Lovejoy, has been hanging around in our night skies for a few weeks now, but it is currently at its brightest and easiest-to-spot part of its journey around our sun.

In contrast, its delicate gas tail is tinted blue due to fluorescing charged molecules of carbon monoxide.
