Description

SH2-091 is a faint Supernova remnant localized in the south of Cygnus near the star Albireo.

Many diffuse and filamentary structures are part of the structure; (SH2-91, SH2-94 and SH2-96 are some of the parts). The whole structure covers a field of more than 4°, which is very similar to the size of the popular Veil nebula.

However SH2-91 is much fainter, and at a larger distance of about 2500 Lightyears as compared with 1500 lightyears for the Veil nebula, and much older (~ 30000 years vs 7500 years).
