This combination of both emission nebula and dark nebula, referred to as NGC1396a has the characteristic form of an Elephant’s trunk. It is part of the much larger nebula NGC1396 in the constellation Cepheus.

An open cluster of stars with the code NGC7380 is mostly known by their illumination of surrounding gas clouds. This so-called Wizard nebula is located in the constellation of Cepheus.

The emission nebula NGC7635, also known as Bubble Nebula in the constellation Cassiopeia. The bubble is created by stellar wind from a massively hot star in the middle.

The very large emission nebula NGC2237, also known as Rosette Nebula, is part of an even much larger area of nebulosity in the constellation Monoceros.

The emission nebula NGC281 in the constellation Cassiopeia, named after the well known videogame character Pacman with which the resemblance is striking.

The emission nebula NGC6888, also known as Crescent nebula, looks like a big brain-like structure surrounded by a lot of H-alpha emitting nebulosity.

Perhaps the most photographed nebula in the night sky, M42, better known as the Orion Nebula in the constellation Orion. And… my first astro image.
