This is the Little Rosette Nebula, an emission nebula located about 7500 light-years from earth in the constellation of Cassiopeia. Named after the more well-known Rosette Nebula in Monoceros due to their morphological similarities, and presented here in the HOS palette. Little Rosette is around 22 arc-minutes in diameter, and its hydrogen and sulphur emissions are reasonably strong but Oxygen is surprisingly weak. It's located in a sea of stars that tend to overwhelm the scene (star reduction is yet another processing technique I need to learn). It has some cool bok globules around the periphery that I will try to enhance on the next iteration. Number 170 in the Sharpless catalogue of H2 (emission) regions.
For an example of this scene with processing that does it justice, take a look at Marcel Drechsler's outstanding example
