Discover the many ways to enjoy observing Comet ISON with our comet observation guide, Binoculars are recommended!
Hopes are rising that Comet ISON will be a Great Comet. If predictions are correct, Comet ISON could turn into a Great Comet which can be observed with the naked eye. Unlike the stars which form constellations, Comet ISON will be seen as being surrounded by a hazy, cloud-like light. Comet ISON can be observed with more clarity and for a longer period if a pair of binoculars or a telescope is used. We recommend using binoculars to observe Comet ISON. As binoculars have a wider field of vision than high powered telescopes, the long tail we know as typical to a comet can be seen in its entirety by using binoculars!

Why not try also taking some photos with a digital camera? Try various ideas such as a tripod to prevent blurring, or using the camera’s “night mode” for your photos. If you get a great shot of Comet ISON, please submit it to our “Mega collection of ‘your observations’ ” on this website.
