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. The bright object in the middle is NGC 346 in changing its shape through the cosmic eras. Massive interactions of light wind heat and star radiation are pushing far away interstellar gas that shines in a wide color spectrum. Few arc minutes on top is visible NGC 371 is an open star cluster surrounded by ionized hydrogen. It has 5 arc minutes size and very active star forming region.
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.
