I finally stopped trusting wide field shots of the Milky Way

Every few weeks someone posts a gorgeous spiral shot of the whole core and everyone gushes. But I noticed a lot of these are composites stacked from data taken over multiple nights with different lenses or even different cameras. Last month a friend in Phoenix shared one he sold as a single exposure, but the star sizes were off and the color gradients didn't match the zenith. I compared his file metadata to my own 90 minute stack from a dark site near Flagstaff and the differences were obvious. The tilt and rotation between frames give away a mosaic or a reprojection. Why does nobody call this out more often? I get that it looks pretty, but calling it a photo when it's really a digital stitching project feels misleading for people just learning. Has anyone else noticed the recent viral shots that claim to be single frames but clearly aren't?

The "digital stitching project" line is what gets me because I used to be the guy defending these shots. I figured if the final image came from real photons someone actually captured, who cares how many frames or nights went into it, that is just processing. Then I tried shooting the core myself and spent a whole night just getting focus right, and seeing a "single exposure" post with perfect corners on a 14mm lens that no lens on earth actually delivers wide open kind of rubbed me the wrong way. What changed my mind was watching a beginner in my local club get down on himself because his honest 30 second sub looked nothing like the viral stuff, and he almost quit over it. Now I check metadata before I gush, and the rotation and tilt clues you mentioned are the first thing I look for.
