Crescent Nebula NGC 6888
It's about 5000 light years away, among the clouds of nebulosity in the Cygnus constellation. The Crescent (or Euro Sign for the currency oriented) comprises a couple of shockwaves produced by the evolution of an energetic Wolf-Rayet star.
Tech Stuff: TV-85/Borg 1.08 flattener/ZWO ASI 533 MC / IDAS LPS-V4 nebula filter/RST 135E mount. Two hours of unguided 15-second exposures integrated and processed in PixInsight. I'm redoing targets which are situated over my house during the summer to enjoy the benefits of more recent technology I've added in the past year (including the strain-wave mount; the 533 camera; and AI processing tools). I'm happy with the way these are giving new life to my scopes including this Televue 85, my first home astronomy purchase. From my yard 10 miles north of NYC.
