The Great Orion Nebula
The Orion Nebula (also known as Messier 42, M42, or NGC 1976) is a diffuse nebula, south of Orion's Belt in the constellation of Orion.
I remember having the opportunity to view Orion through a large telescope many years ago. It was indeed a WOW moment. What struck me was that I could see colour through the eyepiece. The many shades of green were easy seen, but it was the hues of reds and pinks were most impressive. I had never seen red nebulosity through an eyepiece before this experience, and this incredible experience was etched into my mind.
I wanted to capture that vision I had in my head and attempt to recreate an image of that experience. Orion is an incredibly high dynamic range object. It is very bright at its core, includes many dynamic caverns of roiling dust and gas throughout, with beautiful subtle dim wisps of gas everywhere in this complex structure.
This is my first attempt to create an image of Orion. It has its challenges as is quite a complex structure to process to reveal the range of feature within. My highlights would have to be the very subtle wisps of gases, shockwaves, and huge caverns of gas that create this dramatic image.
