The Tarantula Nebula NGC 2070 is a H II region in the Large Magellanic Cloud. It is not in our Milky Way Galaxy. It is 159,800 light years from us and approximately is 8,807 trillion kilometers in radius So, it is BIG!
For those Astro photography nerds among us (Like me.). It was taken with a 508 mm (20 inch) reflector in Siding Springs, New South Wales.

The 958 Megabytes of Fits files were assembled into a TIFF file using Astro Pixel Processor. Then further processed with Lightroom. LR is not a usual program for Astro Photography. I was a Semi professional photographer and it’s the software I know and am most comfortable using.
Astro Photography is really a creative art. The final image reflects the intention of the person producing the image. Even the famous images from the Hubble Space Telescope are that way. The human eye is incapable of seeing the colors that exist in an object. It is up to the person processing the image to produce either a pleasing artistic image or show some scientific process like the types of gasses in the object. In the best outcomes you can do both.
For example, here is my Tarantula Nebula shown next to one by another person.
Both were made the same data.
