Can you see the Bat?
In Celebration of the Halloween Holiday this month. and because i am waiting for a new monochrome camera and filters i decided to re-process my Bat Nebula (NGC 6995)
I think it came out pretty well with only 8 hours of OSC data but i am open to any of your suggestions to perfect the craft. ( What do you think ?)
The Eastern Veil Nebula, and the nebulae in the constellation Cygnus, thought to be remnants of a supernova of the explosion of a star probably 10,000 years ago. The Loop, a strong source of radio waves and X-rays, is still expanding at about 100 km (60 miles) per second. It lies about 1,800 light-years from Earth.
A supernova remnant (SNR) is the structure resulting from the explosion of a star in a supernova. The supernova remnant is bounded by an expanding shock wave, and consists of ejected material expanding from the explosion, and the interstellar material it sweeps up and shocks along the way.
There are two common routes to a supernova: either a massive star may run out of fuel, ceasing to generate fusion energy in its core, and collapsing inward under the force of its own gravity to form a neutron star or a black hole; or a white dwarf star may accrete material from a companion star until it reaches a critical mass and undergoes a thermonuclear explosion.
In either case, the resulting supernova explosion expels much or all of the stellar material with velocities as much as 10% the speed of light (or approximately 30,000 km/s). These speeds are highly supersonic, so a strong shock wave forms ahead of the ejecta. That heats the upstream plasma up to temperatures well above millions of K. The shock continuously slows down over time as it sweeps up the ambient medium, but it can expand over hundreds or thousands of years and over tens of parsecs before its speed falls below the local sound speed.
