Messier Marathon is an annual festival for amateur astronomers where they attempt to view all 110 Deep Space Objects categorised as Messier objects. The effort is made to view all the objects from sunset to sunrise in one single night using a manually operated telescopes only with the help of star maps and relying on their memories or their skills of map reading and translating. Messier Marathon is a fun event where observing all 110 objects is an achievement and even seasoned amateur astronomers sometimes fail to complete the list.
Messier’s List or Messier’s objects is a list of objects comprised by French Astronomer Charles Messier between 1709 till 1764. He was a comet chaser and has discovered 10 comets but while searching for these comets, he came across several objects which he mistakenly assumed as comets and started studying. Frustrated by stumbling upon comet looking objects which were not comets, he decided to catalogue these objects so that other comet hunters does not make the same mistake. Hence came his catalogue originally 104 objects (64 self observed, 40 in coordination with his colleagues) in the late 17th century. The list was later added with more objects which was believed to be observed by him but could not be catalogued due to his long illness.
The new Moon of the month of March/April are ideal for such an activity. The Sun covers that part of the sky which has no deep space objects. It means the Sun is not blocking any region in space which has a Messier object in the close vicinity. The first of the constellations to explore are Cassiopeia followed by Perseus and Taurus. The sky till the sunrise cover all 110 messier’s objects and hence people can have a wonderful and enjoyable race. Another reason for choosing the moonless sky is that the sky remains dark and free from natural light. It enables the amateurs in searching the objects from sunset and till sunrise. The second half of March is more favoured so if the new moon falls in the first half of March, one can wait till early April for the event.
As the preferred night for Messier Marathon is a new moon night in the month of March and April, We are organising two events for the same. You can register for both however due to COVID-19 restrictions, we will take limited entries for the same. Scroll down for day wise plan.
