That guy at the star party who argued stacking kills the soul of astrophotography

Last month at the Dark Sky gathering near Flagstaff I set up my gear next to a guy with a vintage Celestron. He watched me process 3 hours of Andromeda subs on my laptop. Said stacking ruins the authenticity of what you actually see through the eyepiece. I told him stacking reveals detail the naked eye can't catch. He pointed at my final image and said its fake light from a computer. I get the purist side about raw visual observation. But my image showed faint dust lanes his scope never picked up. Does processing cross a line or is it just a better tool for seeing deeper? I want to hear both sides from this community.

Man that's a rough encounter. I get where he's coming from, the whole raw eyepiece experience is special in its own way. But calling it fake light is kind of harsh, stacking just pulls out what's already there, it's not like you're painting in details that don't exist. Sort of feels like telling a painter their canvas is fake because they mixed colors instead of using pure pigment. There's room for both approaches without one being more "real" than the other.

That painter analogy hits hard, but here's the thing - when a painter mixes colors, they're still deciding what goes where. With stacking, you're just letting the software average out noise. So where's the line between "bringing out what's there" and basically guessing what the camera didn't quite catch? I've tried stacking on a faint nebula once and ended up with stars that looked nothing like what I saw in the single frames. Makes me wonder if we're actually seeing the same object or just a really good approximation of it.
