The tarantula mist, or NGC 2070, is already visible to the naked eye in the clouds of the Great Magellan at the eastern end. The tarantula mist is the most famous extragalactic target of the Great Magellanic Cloud. The Tarantula Nebula is a huge HII area, and may be even the second largest in the entire Local Group, only the NGC 604 of the Triangle Galaxy can be bigger than that. With the telescope, the Tarantulas mist appears as a clear and compact misty spot that clears clearly towards the center. In the middle of the fog, two star-like brightnesses can be distinguished. The OIII filter did little to help detect fog, but it looked just fine without the filter.

Nebulae

  In an emission nebula the hot stars nearby cause the gas glow. This should not mix with reflection nebula, where the gas is only lit up by nearby stars.
  
  The appearance of a gas nebula is irregular, and the fainter parts of it need bigger instruments to be visible.
