The Cygnus region in the Milky Way a.k.a The Swan which can be seen high in the summer skies on the Northern Hemisphere. The red glowing regions are energized hydrogen alpha (Ha) which unfortunately is too feint to be seen with the naked eye.
The photo was taken from Stevns in Denmark at a weekend stay at The Norrmans where I had a few hours in the hotel garden after normal people’s bedtime ✨🔭📸😁

The most prominent nebula seen to the right is The North America Nebula (NGC 7000) so called due to its obvious shape, and right next to it on the right side is the feinter Pelican Nebula (IC 5070 & IC 5067).
Continuing towards the right upper corner are some more Ha-regions without any name (as far as I know) but at its outerskirts can be seen the very small Crescent Nebula (NGC 6888) – you propably need to know where it is to see it but its very clearly there if you zoom in 😏
At the bottom right hand corner are the two The Veil Nebulas (Caldwell 33 & Caldwell 34) and this is my first image of those (but definitely not the last) 😄

The Pelican Nebula is an HII region and is 1800 light years from Earth.

The Veil Nebulas are approximately 2400 light years away and was created by a super nova from a star 20 times more massive than the Sun which exploded between 10,000 and 20,000 years ago.
The Veil Nebulas together are also called The Cygnus Loop and covers the apparent space of 3 full Moons!

The North America Nebula is a Ha region and was first discovered in 1786 by William Herschel although its 2590 light years away – however its apparent size covers an area 10 times the full Moon!

The Crescent Nebula is an emission nebula and is about 4.700 light-years away and was also discovered by William Herschel but in 1792. Its apparent size is about half of the full Moon.
If you want to look for it in this photo you can see what to look for here: Crescent Nebula (its tilted 90 degrees compared to this photo).
