M45 - 25.1.2022 at 19.30 - 25.1.2022 at 22.10 Kirkkonummi, Komakallio Observation number 104296

Visibility IV / V

Samuli Vuorinen, Kirkkonummen komeetta

I photographed the Seulaste constellation in the constellation Taurus on two nights in January, for a total of five hours. If the weather had favored, I would have photographed this subject for much longer, but clear moonless climates have been rare. Somewhat dim clouds of dust still stand out around the Screens, and I'm quite happy with the result.

      Reflection nebula is gas only lit up by nearby stars. It should not be mix up with emission nebula, where hot stars nearby cause the gas glow. But then reflection nebulae are visible in the same areas with emission nebulae. The appearance of reflection nebulae is irregular, and many of them need bigger instruments to be visible.

       

      Reflection nebulae are glowing blue around the stars of Pleyades. Image Juha Parvio.

       

      The blue glowing reflection nebula NGC 1333 around the bright star is in Perseus. Image Timo Inkinen.

       

      The bluish reflection nebula NGC 2023 is located lower left from the Horsehead Nebula. The Horsehead Nebula itself is a dark nebula in the front of red emission nebula IC 434. In the left side there is NGC 2024 aka Flame Nebula. Image Samuli Vuorinen.

       

      NGC 7538 in Cepheus is a combination of reflection and emission nebula. Image Timo Inkinen.

    • Open cluster info

      Open cluster is an irregular group of tens or hundreds of stars. It can be visible as separate stars or a bit fuzzy spot with small instrument.

      There is the open cluster M52 on the right edge of the image. The red emission nebula is the Bubble Nebula. Image Jyrki Grönroos.

      M34 is also an open cluster in Perseus. Image Teppo Laitinen.

       

      The Wild Duck Cluster M11 is an exceptional dense open cluster. Image Jaakko Asikainen.

       

       

      The Ptolemy's Cluster M7 is located in a rich-star area of The Milky Way in Sagittarius. Image Toni Veikkolainen.
