OBJECT DESCRIPTION AND IMAGE SESSION

The SMC is an irregular galaxy type. It might be distorted by the gravitational forces of our Milky Way and the LMC. Interesting to see a variety of extra galactic objects like nebulae and star clusters which can be reached through amateurs telescopes. At the right Globular Cluster NGC 104 separated by only 90 arc minutes (apparent distance), NGC 362 is up and shines at magnitude 6.8 with 14 arc minutes size.

Despite its high magnitude the cloud is not visible through binoculars from my backyard in Martinez (30 km north Buenos Aires). I can glimpse NGC 104 but no single feature of the galaxy. However in clears skies is a joy for the naked eye.

The SMC and LMC were certainly known through ages by the southerners. It became known to the world when Fernando de Magallanes went on his journey around the world in 1519.
