M42 Orion Nebula Revisited-DeNoiseAI-low-light
I’ve been playing with a new workflow and tools in Pixinsight using Cuiv’s mastering Pixinsight YouTube video as inspiration and a guide. I thought I would have a go at re-processing the data I captured on February 26th, 2021. It is, in effect, a rework of the image I posted on March 3rd, 2021 [https://www.flickr.com/photos/matt3775/51000661947]. The nebula's centre isn’t ideal, but this resulted from trying to reduce the overall brightness of the Trapezium Cluster, which was blowing the whole centre out.
The main subject nebulosity is M42, The Orion Nebula, an emission-reflection region. Just above M42 is the smaller nebulosity surrounding the irregular variable star HD37061, known as De Mairan’s Nebula or M43.
Using Pixinsght, the background was extracted using Seti Astro’s Automatic DBE before using Russel Crowman’s BlurXterminator and NoiseXterminator.
