About this image

Sharpless 2-91 Cyg is the Deep Sky Section's August 'Object of Interest'. This exposure, using the COAST, also revealed no sign of the elusive supernova remnant! Better conditions, bigger aperture and wider field of view but exposure limited to 120sec. I will try again with the Unistellar . . . Herausforderungen!

(I post these non-images on the grounds that a negative result is still a datum)
