Description

Vulpecula reminds me always of my initial night-sky exploration attempts, star hopping trying to find M27 or the cluster IC399. Other beautiful objects like NGC6820, presented here, were out of range, and curiosity piled up, building the motivation to start eventually the journey with astrophotography.

I recorded the sub-exposures during 3 short summer solstice nights: 11, 12 and 14 June 2022. Notwithstanding the full moon and the urban sky (by the way, a restaurant in the vicinity introduced recently the innovation of rotating sky lights to draw attention) the signal was there.
Though smaller than the more popular nebulae in Cygnus and Cepheus, NGC6820 is a beautiful object with its young stars illuminating and blowing away their cosmic matter mother.

Here some technical info mostly from wikipedia.
NGC6820 and NGC6823 Vulpecula Nebula and Cluster
NGC 6820 is a small reflection nebula near the open cluster NGC 6823 in Vulpecula. The reflection nebula and cluster are embedded in a large faint emission nebula called Sh 2-86. The whole area of nebulosity is often referred to as NGC 6820.
Open star cluster NGC 6823 is about 50 light-years across and lies about 6,000 light-years away. The center of the cluster formed about two million years ago and is dominated in brightness by a host of bright young blue stars. Outer parts of the cluster contain even younger stars. It forms the core of the Vulpecula OB1 stellar association.
The huge pillars of gas and dust are formed when surrounding gas and dust is pushed and eroded away by stellar winds and radiation from the brightest cluster stars. Dark globules of gas and dust (Bok globules) are also visible in the nebula.
Bok globules, named after the Dutch astronomer Bart Bok (1906-1983), who proposed their existence in the 1940′s, are dark clouds of dense cosmic dust and gas within star-forming regions in which usually star formation takes place. They most commonly result in the formation of double or multiple star systems.
