Image Description:

On a rocky summit of an icy planet sits a remote research outpost. This frozen world orbits a inconspicuous star in a minor arm of a giant barred spiral galaxy.

Named after a mythical creature of an ancient culture that once dominated the planet, this scientific outpost is called the Sphinx. The Spinx is mythicized to have mercilessly killed those who couldn't answer her riddle.

The Sphinx station has a prime view on one of the galaxies major star forming regions, named after another mythological figure, a giant hunter. Not all scientific riddles within the hunter are solved yet, but fortunately the Sphinx hasn't killed any scientists so far.

The thin atmosphere of the planet at this high altitude location contains enough water to form clouds, which shroud the observatory in freezing fog about 40% of the time. If the clouds part, the hunter's giant molecular clouds of ionized hydrogen are lighting up the sky.

I had the opportunity to visit the Sphinx outpost with benjaminbarakat in September for a night of astrophotography. After a sternous night, we were happy that both the planet and the mythical creatures had shown mercy. The hunter had made its appearance and we escaped this stunning place without getting killed by lack of oxygen, the cold or the wrath of the Sphinx.

The Horsehead is one of the most famous nebulae on the sky. The horse-head feature is dark because it is really an opaque dust cloud that lies in front of the bright emission nebula. Like clouds in Earth's atmosphere, this cosmic cloud has assumed a recognizable shape by chance. After many thousands of years, the internal motions of the cloud will surely alter its appearance. The emission nebula's color is caused by electrons recombining with protons to form hydrogen atoms. On the image left is the Flame Nebula that also contains filaments of dark dust. Just to the lower left of the Horsehead nebula is a blueish reflection nebulae that preferentially reflects the blue light from nearby stars.

This target was what got me into Astrophotography many years ago but I could never do it justice in the UK with the light-polluted skies in Birmingham so now living in Spain and running a Remote Telescope Hosting site I have been able to collect better quality data and do it more justice.
