Pickering’s Tri­angle in Cygnus

Pickering’s Tri­angle is the middle part of the Cygnus Loop, a super­nova rem­nant with an age of about 15’000 years. It is much faint­er than NGC 6992 (East­ern Part) and NGC 6960 (West­ern Part) and has no NGC num­ber assigned. It was dis­coverd by Wil­li­am­ina Flem­ing but cred­ited to Edward Pick­er­ing, the dir­ect­or of her observatory.
