This latest capture from Grand Mesa Observatory’s system 4 (available on our subscriptions from October 1st) using a QHY367C full frame One Shot Color CMOS camera on a Takahashi E-180 F2.8 Astrograph with a William Optics STC Astro Duo-Narrowband Filter that we are testing for William Optics . This data really took me by surprise, I am very excited to see the level of detail and high transmission the STC provides in the H Alpha and OIII bandwidths especially for a project that was captured in just over 4 hours.
Total Acquisition Time 4.08 hours

Containing many components such as The Eastern & Western Veil Nebulae NGC6960, NGC6992, NGC6995, IC1340, Pickerings Triangle, NGC6974 and NGC6979. Cygnus Loop is a supernova remnant, the expanding cloud of diverse elements created in the most powerful of explosions; a supernova.
As a Massive star nears the end of its life, it runs out of hydrogen fuel and begins fusing helium. After exhausting its supply of helium it begins to fuse heavier elements until finally, the star's core can no longer exert enough outward pressure and it collapses. A shock wave rebounds through the star so fierce that the star is shredded and leaves behind a small but extremely dense body; either a neutron star or a black hole.
The progenitor of this supernova remnant exploded more than 5,000 years ago and over the course of the past 5 millennia, the material has been racing away in all directions. The Cygnus loop now occupies a vast region of sky, equal to 36 full moons!
A Supernova seeds the interstellar medium with all types of heavy elements. In fact, every single atom of elements heavier than iron was created in this type of event, including many in your own body.
