NGC 7000, IC 5070 - 2.10.2019 at 21.30 - 3.10.2019 at 03.00 Rovaniemi Observation number 85937

Visibility Unclassified

Lauri Turunen, Corona Borealis, Rovaniemi

Thanks to a rare good shooting night, I got a record 5 hours of exposure from this handsome subject in the Swan Tail area. The new RedCat51 lens starts to show its nails when focusing, polar aiming and tracking are noisy. Setting up the set to full shooting condition only takes a quarter, which is a good thing for future winter shooting sessions.

Nebulae
- Emission nebula
  
  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.
Star clusters and asterisms
- Open cluster
  
  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.
