Description

This is a Narrowband image of NGC 2029, which is an area of emission nebulae in the LMC. I recently published LRGB and HaRGB images for this same FOV. This is a modified SHO image. The SHO combination, conventionally called the Hubble Palette, as you all know, maps SII to Red, Ha to Green and OIII to Blue. It does however produce quite garish colours and pink stars.The mix is therefore often modified to give a more aesthetically pleasing image, but one where the abundance of the chemical species is still well mapped in a colour image. After some experimentation I went with:
Red: 50% SII + 50% Ha
Green: 20% Ha + 70% OIII
Blue: 100% OIII
I removed the stars with StarXTerminator, before processing the image. Previously I had removed the RGB stars in processing the LRGB image and I was able to use Pixel Math to add them back to this finished image, to give a much more pleasing star field.
The amazing tendrils of gas come through well in this version and I hope you like it, both for its scientific value in mapping the presence of Hydrogen, Oxygen and Sulphur in this region of the sky, but also for its aesthetics.
