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.

The night was windy and with the Moon around 1/4 stage or close to 1/3. I had to finish the session because I have run out the Power of the NEQ6.

The Jenna Carl Zeiss and the QSI 583 are a nice combo for this target.
