IC 2118 Witch Head Nebula IC 2118

The Witch Head Nebula is a striking and eerie interstellar cloud of dust and gas located in the constellation Orion. Its distinct shape, resembling the profile of a witch’s face in profile, is created by the illumination of nearby stars. This nebula spans about 50 light-years across and is primarily composed of hydrogen gas, which glows faintly in the presence of ultraviolet radiation from neighboring stars. The nebula is a site of ongoing star formation, with young, hot stars embedded within its dusty tendrils. Captivating and mysterious, the Witch Head Nebula is a captivating sight in the night sky, sparking the imagination of astronomers and stargazers alike.

Chasing darkness in Switzerland 2021 – Flims Laax

I haven’t been able to photograph the stars for a very long time. I live in a valley where many rivers flow, which brings a lot of moisture into the air. This moisture condenses, which forms either fog or clouds. I was sick of this weather and decided to climb above the clouds and finally take some pictures. Like last year I chose Berghaus Nagens in Flims/Laax ski resort and combine this trip with a skiing vacation. So, how was it? Well, I have bad luck this year. I got only a single cloudless night out of five. Moreover, it was the last one. So, I was not able to photograph the whole night and around midnight I had to pack the gear.

There is a time wrap made by GoPro Hero 8 Black. A view to the south direction. Orion is rising, snowcats are preparing the slopes and the only light pollution comes from city Milan, which is 100 km away.

The primary target was a very difficult one – IC 2118 Witch Head Nebula. This reflection nebula is illuminated by the supergiant star Rigel (right leg of the Orion constellation). The dark skies are the essence and the Askar mini telescope did the job. However, I was surprised how terrible was the chromatic aberration. This can be partially corrected in postprocessing, but not fully. I think I will have to find a better scope.

Before the Orion constellation rose up, I captured the M45 Pleiades. It’s an integration of 63 frames each 2 minutes long. Here, the dark skies reveal some dark nebulae in the visual surroundings of the star cluster. Again, I was quite disappointed by the chromatic aberration of the Askar telescope.
