Processed vs raw astrophotography: which tells the real story?

Last month I spent 3 nights shooting the Orion Nebula from my backyard in Flagstaff, and when I posted the heavily processed version with stretched curves and noise reduction, someone commented that it wasn't a real photo anymore. But the raw stack straight out of DeepSkyStacker looked like a grey smudge with no color at all. Do we think processing is cheating or just part of the workflow for deep sky objects?

The 48 hours I spent processing my first decent Horsehead Nebula shot made me realize the raw data is just the starting point, not the final truth. Processing is basically just making the invisible visible, like how your eyes adjust to see stars when you stare long enough but with math instead of biology. I used to side with the "real photo" crowd until I saw what actually comes off the sensor compared to what's hiding in that noise.

Fiona, that 48 hours of work really shows how much hidden detail is waiting to be pulled out of the data.
