IC 1805 - 19.12.2018 at 23.00 Kirkkonummi Observation number 83399

Visibility Unclassified

Jari Saukkonen, Kirkkonummen komeetta

Heart mist is a classic destination in the winter sky. So, now is June? Yeah, sometimes in these projects a little stretch :-). The material for this image had to be filmed during other projects during November / December, and now it finally got the attention it deserved from the processing queue (which is therefore not yet empty).

This emission fog range is very wide, the image field would fit horizontally for five full months. Even when you could see these with the naked eye, there would be wonder in heaven!

In the second and triple images, details of the Melotte 15 constellation engraved in the nebula formation, as well as the so-called fish head mist IC 1795.

      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.

       

      Emssion nebulae in Cepheus. The bigger part is composed of the nebulae Cederblad 214 (Ced214) and NGC 7822. The lower round nebula is called Sharpless 170 (Sh2-170). Image J-P Metsävainio.

      In this 4-degree-field there are emission nebulae Sh2-157, Sh2-158, Sh2-159, Sh2-161 and Sh2-162 (or NGC 7635 aka Bubble Nebula) and open clusters M52 and NGC 7510. Image Juha Kepsu.

       

      NGC 281 aka Pacman Nebula. The object is in Cassiopeia. Image J-P Metsävainio.

       

      NGC 896 in Cassiopeia is the tip of Heart Nebula (IC 1805). 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.

       

      The open cluster M45 aka Pleyades. Image Juha Parvio.

       

      The pair of the open clusters NGC 869 and NGC 884 aka the Double Cluster in Perseus. Image Lauri Kangas.

       

      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.
