NGC 6979 - 24.8.2020 at 23.00 - 25.8.2020 at 00.00 Kangaslampi Observation number 95050

Visibility IV / V

Erik Pirtala, Warkauden Kassiopeia

I photographed this among the first targets of the Pickering Triangle season found in the constellation of Swan in August. This treatment has produced quite a bit of gray hair, but I would think it is finally done. The Pickering triangle is found between the eastern and western gauze nebula, belonging to the same large supernova remnant. The picture shows a total of 9 hours of exposure in the HOO palette.

      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 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.
