Lagoon and Trifid Nebula from Namibia

Astrotrac/Polarie Posted on Sun, November 13, 2011 16:37:40

The Lagoon and Trifid nebulae are two famous nebulae in Sagittarius, and both nebulae can be seen with the naked eye from a dark site such as Hakos Namibia. They are easy to see with binoculars. This picture shows these two nebulae against the background of the dense star fields of the Sagittarius Arm of the Galaxy. The Lagoon nebula (Messier 8) is the larger (and brighter) nebula to the south of the smaller Trifid nebula (Messier 20).
3 August 2011:
I had while photographing these objects some problems with the Astrotrac mount. Unfortunately , from the 20 shots taken only two could be used for stacking. Even so, it is still a good result

Helix Nebula from Namibia

Astrotrac/Polarie Posted on Sun, November 13, 2011 11:28:21

The Helix Nebula is an example of a planetary nebula, or ‘planetary’ formed at the end of a star’s evolution. Gases from the star in the surrounding space appear, from our vantage point, as if we are looking down a helix structure. The remnant central stellar core, known as a planetary nebula nucleus or PNN, is destined to become a white dwarf star. The observed glow of the central star is so energetic that it causes the previously expelled gases to brightly fluoresce.

The Helix Nebula in the constellation of Aquarius lies about 700 light-years away, spanning about 0.8 parsec or 2.5 light-years. Currently, the age is estimated to be 10,600+2,300 −1,200 years, based solely upon a measured expansion rate of 31 km·s−1. (wikipedia)
