The Philippine Messier Marathon Open is an annual star party conducted under the dark clear skies of Caliraya, Laguna, where astronomy-enthusiasts in the country gather to observe and meet fellow enthusiasts. This event hosted by the Astronomical League of the Philippines is by far the largest star party and astro-gathering in the Philippines.

The highlight of the event is the Messier Marathon where astro-enthusiasts attempt to observe and identify all the 110 m-objects in just one night. This image was taken earlier today, March 25, 2012, at sunrise. For more info, click here.
