CHASING DARKNESS IN SWITZERLAND 2024 – FLIMS LAAX

Last four winters we spent our skiing vacation in the same place – Flims-Laax ski resort. Specifically, in Berghaus Nagens. This small ski hotel is at the end of the gondola at 2200 meters above sea level. This means the nearest street lamps are far away. However, the hotel is surrounded by ski slopes. The slopes need to be prepared by snow groomers, which illuminate the white snow. This spoils a bit otherwise very dark sky. However, the main reason was to enjoy the skiing vacation and the starry nights are just an add-on. Last year I struggled with the battery, which froze after a few minutes outside. I purchased a dedicated astro-battery this year and was fortunate with the weather. 4 cloudless nights in one week – I really didn’t expect that to happen.

The initial plan was to capture the Witch Head Nebula, then some dark nebulae in Taurus, and if time allows Pleiades. It went well, so I am slowly preparing a plan for next year.

Dark nebulae in Taurus

Constellation Taurus is full of deep space gems. Probably everybody knows the Pleiades open cluster. There are many dark nebulae next to it, which I intended to capture during our winter vacation in Flims-Laax. Three and half hours of total exposure revealed 3D structures of the dark clouds floating in space. The darkest cloud on the left side is B 22 Taurus Dark Cloud Complex, the small one on the left B 207 Eagle’s Head, and the central part B 18 Kutner’s Cloud.

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.
