OBJECT DESCRIPTION AND IMAGE SESSION

Our nearby galaxy (after Sagittarius Dwarf Galaxy) is one of the marvelous sight of the southern sky. First spotted by Persian astronomers and afterwards by Amerigo Vespucci, but it was by Ferdinand Magellan on his voyage in 1519 who brought it to popularity.

Like many irregular galaxies the LMC is very rich in dust and HII regions. Right now is under a intense process of star formation activity.

This was the first try in a new location near Mercedes City 108 km away from Buenos Aires. The night was not at all transparent because cirrus and dust. We decided to aim to this generous target. Despite the night conditions the TMB 92 and QSI 583 combo, were able to gather a bunch of photons. No electricity was used, so the equipment were fed by a gas generator provided by Juan Destefani. In the future we expect to have the whole equipment running with car batteries.
