NGC 2174 - 28.1.2022 at 18.00 - 28.1.2022 at 23.00 Nakkila Observation number 104349

Visibility IV / V

Tomi Kurri, Porin Karhunvartijat

The moonlit and clear night that hit Friday offered an opportunity to go through new deep sky destinations for yourself. This time the Monkey Head Nebula, located right in the upper corner of the constellation Orion, near Gemini, was chosen as the subject.

This emission mist is located at a distance of about 6400 light-years. SkySafari gives the magnitude of the fog at +7.59, so it's a fairly bright destination.

The weather favored the whole early evening and I finally got a total of exactly 5 hours of exposure time with a color camera through the narrowband filter.

      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.
