Veil nebula is a supernova remnant – hot and ionized gas and dust floating in the universe, as a remainder of a mighty star, which once shined (roughly before 5 – 8 thousand of years), locate in constellation Cygnus (swan). This nebula is relatively close to Earth – only 1470 light years, therefore the visual angle is huge – approximately 3 degrees, which is six times the diameter of the Moon.
The picture is composed by bi-color technique. Two narrow band pictures were taken (Ha and OIII). H alpha was used for red channel and OIII for green and blue. Since I used quite long focal length (1000 mm) the whole DSO didn’t fit in the field of view of the camera. Next time I will try to use shorter one.
