Finally caught that one detail in Orion photos that everyone seems to miss

It took me six months of comparing my stacked images to the pros before I realized they were all adjusting the hydrogen-alpha channel separately to bring out the Barnard's Loop arc, and now my widefield shots actually look like the nebula is glowing instead of just being a flat red smear - has anyone else found that one processing trick that made everything click for them?

Is this really that deep though? I mean Barnard's Loop shows up fine in most basic stretches if your sub exposures aren't garbage. Sounds like overthinking it to me. I just use the same process on every channel and it works out fine.

Buddy of mine tried that exact method @eric723 and ended up clipping all his Ha data to black...
