After nearly a year, I revisited the Cygnus Loop and added another two hours to last year's data — bringing the total integration to 3 hours and 45 minutes. After three weeks of cloudy Ohio skies, we finally caught a clear night and made the most of it. In typical Ohio fashion it was cold, but thankfully the moon held off until later in the night.
This session came right off the heels of a collaborative imaging run on Markarian's Chain, so it was already shaping up to be a productive night. Having the extra data to stack on top of last year's capture made a noticeable difference — I think this version is a significant step up from where it was.
The Cygnus Loop is a supernova remnant spanning roughly 3 degrees across the sky, making it a perfect target for the Rokinon's wide field of view. Captured with the Rokinon 135mm f/2 | ASI533MC Pro | SV220 dual-band filter | Sky-Watcher EQ6-R Pro — the dual-band filter really helped pull out the nebula's detail against the busy Milky Way backdrop.
