Description

The supernova remnant G65.3+5.7 in Cygnus is a huge structure with a size of ca. 3.5° x 4.5°. It shows niche structures mainly in OIII. The object was discovered and classified as a SNR by Gulf et al. in 1977. Before its main elements Sh2-91, Sh2-94 and Sh2-96 were already catalogued in the Sharpless catalogue as single independent structures. The image was shot with my vintage SMC Pentax-M 135/3.5 lens at f/5.6.
