Imaging the Crescent Nebula (NGC6888) without UHC and OIII filter

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.
