    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.

• 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.
