The Fish Head Nebula IC 1795 - NGC 896
This galactic object is part of a large star-forming system of gas and dust located along the Perseus Arm of the Milky Way. The nebula is located in the constellation Cassiopeia, about 6,000 light years from Earth, and can be found about 5 degrees south-east of the star ε Cassiopeiae, but it can also be located by starting from the Perseus Double Cluster and moving about 5 degrees north-north-east adjacent to the much larger Heart Nebula. The brightest region of the nebula is called NGC 896 and is home to many young, large stars. These stars radiate large amounts of ultraviolet light. This UV radiation excites the surrounding gas and causes it to glow brightly. The entire complex of nebulae visible in this area is circumpolar from most regions of the northern hemisphere; the best months for observation are from October to April.
The image obtained is a composition of three gases: sulphur (SII), hydrogen (Ha) and oxygen (OIII), assigned respectively to the R, G and B channels of the image. This false-colour SHO composition is common to many of the images from the Hubble Space Telescope, from which the palette takes its name. The channels assembled in this way also give rise to the characteristic magenta colour of the stars typical of the Hubble SHO palette.
