Last week I found out my 'stacked' astro photos had a hidden flaw for 3 years

I started stacking back in 2021 and always thought my nebula shots looked a little fuzzy. Last week I ran my old data through a new calibration frame workflow and realised I'd been using the wrong bias frames the whole time. My M42 from 3 years ago suddenly looks crisp and detailed. Has anyone else dug up old data and fixed it with better processing?

Wait, did you have to re-calibrate all your old subs or just the masters? I had a similar thing happen with my flats last year, I kept getting these weird gradients in all my shots and it turned out I was taking the flats at the wrong focus point. Took me like 6 months to realize my LensUtility settings were off the whole time. I ended up going back through like 2 years of data and reprocessing everything with the right flats, and it made such a huge difference on my Orion shots too. It sucks losing that time but at least now you have way better images to show for it.
