NGC1499 (California Nebula), an emission nebula located in the constellation Perseus is a very large and colourful target when photographed in narrow-band. Here an SHO image of long exposure to bring out some of the very faint blue OIII signal.

The Tadpoles nebula is a very characteristic nebula in the constellation Auriga. This narrow-band image in Hubble palette clearly shows where this emission nebula gets its name from.

The beautiful Jellyfish nebula (IC443) in the constellation Gemini. Here in a wide-field shot together with reflection nebula IC444. The narrow-band images are processed in the SHO Hubble palette.

An old 2019 dataset of Sh2-155, also known as Cave Nebula, was finally processed to this image in SHO Hubble palette. The nebula itself is only a small object in a much larger region of all sorts of emission, reflection and dark nebulosity.

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