IC405 is an interesting combination of both a reflection and emission nebula that emits strongly in H-alpha. The double-star AE Aurigae shines brightly in the middle and illuminates vast clouds of hydrogen gas.

Face-on view of the intermediate spiral galaxy NGC9646, or Fireworks galaxy, right on the border of the constellations Cepheus and Cygnus.

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