The Crescent Nebula is an emission nebula in constellation Cygnus. It was discovered by William Herschel in 1792. The apparent magnitude is around 7.4mag.
I imaged the nebula without UHC or OIII filter – that’s why is actually looks quite unspectacular.
The image is also available in full resolution.
