Description

This picture was taken in summer 2015 and it waited for a long time to be processed. I was not satisfied with framing since part of nebula still remained outside of frame.

Nevertheless, processing showed a beautiful strings of Pickering's Triangle and I just had to share it with you.

Pickering's triangle is a part of Vail supernova remnant in the constellation Cygnus (NGC 6960, NGC 6992, NGC 6995, IC 1340).

Age of supernova remnant is approximated to 6-8 k years.
