Messier Marathon 2014

A full night event by Big Bang Astronomy Club

Big Bang Astronomy Club is proposing to host a Messier Marathon event for the year of 2014 at Shri O. V. Seth Regional Community Science Centre, Rajkot. The event is scheduled for night of 29-30 March 2014.

What is a Messier Marathon?

A Messier marathon is an attempt, usually organized by amateur astronomers, to find as many Messier objects as possible during one night. The Messier catalogue was compiled by French astronomer Charles Messier during the late 18th century and consists of 110 relatively bright deep sky objects (galaxies, nebulae, and star clusters). (source: Wikipedia)

Why is Messier Marathon is being organized in March?

The number of Messier objects visible in any one night varies depending on a few factors, including the location of the observer, the duration of daylight/nighttime, and the season (the positions of the Messier objects relative to the sun varies with the season). At low northern latitudes, particularly around latitude 25° north, it is possible to observe all Messier objects in one night during a window of a few weeks from mid-March to early April. In that period the dark nights around the time of the new moon are best for a Messier Marathon.

What is the registration fee?

Rs. 300/- for non-members
