That guy with the laser pointer at the observatory changed how I see stacking
Last month at the Griffith Park public night, some older dude next to me kept talking over my shot setup, real pushy, pointing at my DSLR on the tracker. He said I was wasting my time exposing single frames when the sky was this steady. I almost ignored him, but he walked me through his workflow right there on his phone, showed me 80 raw files from one target and how he rejected half of them for slight satellite trails or soft focus. I always just auto-stacked everything and wondered why my nebulae looked mushy. Tried his method that night on Orion, tossed out 40 of my 120 subs, and the final result was way sharper than anything I'd done in two years. Has anyone else had a random stranger's nitpicking actually fix their whole process, or is that just me?
Watching a stranger fix your whole process in five minutes hits different because it shows how much we just coast on autopilot. Same thing happens with cooking, lifting, or even how you fold laundry, where some random tip from a coworker or guy at the gym rewires years of habit. The hard part is staying open when someone's being annoying, since the best advice usually comes wrapped in the worst delivery.
