Vent: Someone told me my nebula photos were too 'blue-heavy'

Yeah, so I posted my image of the Orion Nebula from last fall and a user straight up said I was crushing the blues too much. I went back to my raw data in DSS and realized I was over-stretching the Ha and OIII channels. Now I calibrate my white balance to 5500K before stacking and it looks way more natural. Anyone else get feedback that completely changed their processing workflow?

Haven't you ever noticed that real color balance in space objects is way more subjective than people let on? I mean, the data we capture is just numbers until we decide what they mean visually. I get what you're saying about the 5500K calibration, but I've actually started embracing a slight blue bias in my Orion shots because that's how the gas actually behaves at those wavelengths. The "natural" look people push for is just what happens when you flatten the signal to mimic what our eyes would see from 1,500 light years away, which is already a compromise. So I guess I'd push back gently and say don't overcorrect just because one person said it looked off. Your original processing might have been closer to the real physics than the sterile calibration you're doing now.

Wait, so you're telling me there's more to astrophotography than just cranking the saturation slider to 11 and calling it a day? I've been out here thinking my nebula pics looked like they were taken from the bottom of a pool filter. Guess I should actually calibrate my gear instead of just blaming the camera for being weird.
