G082.2+5.3 - 18.11.2022 at 02.00 Fregenal de la Sierra, Espanja Observation number 110879

Visibility I / V

Tapio Lahtinen, Tampereen Ursa

This project started already in September, but due to technical problems and the weather, the project came to some kind of conclusion only now.
The main object itself, the supernova remnant, still remained very thin, so the project must be continued next year as well.
But the Ha-data looked so interesting, even aesthetic, that I dare to display the image 'raw' as well.
The second image is the starless version and the third is just the Ha data colored.

      Supernova remnant is the remnant of the big star died in supernova explosion. The supernova remnants are quite irregularly shaped. Rather many of them ring-like strusture.

      The moderate big instruments and possibly special filters are needed to see supernova remnants.


      The Crab Nebula was born in a star explosion in  1054. This is the easiest supernova remnant in the sky to observe. Image Tero Hirvikoski.


      The supernova remnant Simesis 147 is in Taurs and Auriga. Image J-P Metsävainio.


      The Veil Nebula in Cygnus is wide-area supernova remnant in the sky. There is a detailed image of the boxed area. Image J-P Metsävainio.


      This detail of Veil Nebula is known as Pickering's Triangle. Image J-P metsävainio.
