Chicken Head

Chicken Head

This image was created using both broadband and narrowband filters—seven filters in total. When I first created the RGB image, it looked flat. I thought I would include the narrowband data that I captured and combine the two. To my eye, I like the true colour palette, but it really lacked the depth that was in the Hubble Palette. Revealing the blue near the centre was one of my goals. This is my attempt at combining seven filters into an image.

 

Gum 39, also known as RCW 32, is an emission nebula located in the constellation of Centaurus in the southern sky. It is the larger object to the left. Gum 40, also known as IC 2872, is another emission nebula, the smaller object in the lower right part of the frame. They are situated in the southern part of the constellation, near the border with the constellation Crux. They are named after the Australian astronomer Colin S. Gum, who catalogued them in his Gum Catalogue of HII Regions in 1955.

 

Gum 39 is a region of ionised hydrogen gas illuminated by nearby hot, massive stars. These stars emit intense ultraviolet radiation, which ionises the surrounding hydrogen gas and causes it to glow. The nebula is a diffuse, glowing cloud of gas displaying intricate structures and filaments.

 

Within Gum 39, there may be star formation regions where dense pockets of gas and dust are collapsing under gravity to form new stars. These regions are often characterised by young, massive stars surrounded by dusty cocoons.
