Pickering's (or Fleming's) Triangle
Any part of the Cygnus loop is a treat for visual astronomers and astrophotographers alike. The many intricacies of its structure make it unique in the night sky.
I shot Pickering's Triangle through narrowband filters with the intent of producing a Hubble palette (SHO) image. However, the SII signal was largely superimposed on the Ha and didn't add anything useful, so I left out the SII and made a bicolor image with the other two filters. Here's the link:
Thanks for looking.
