I always stacked my star photos to fight noise, but one clear night in Sedona changed my mind

Last week I was out at the airport overlook near Sedona, Arizona, and decided to just take a single 30-second shot of the Milky Way with my old camera. I figured it would be a grainy mess. When I got home and looked, the detail in that one frame was actually cleaner than my usual 20-image stacks. I think the super dry air and zero moon made the difference. Anyone else get a surprisingly good single exposure?

Read that dark skies matter more than gear.

Honestly, the camera sensor itself might be part of it. My old camera always ran cooler at night in the desert, not just from the air but because the ground was cold too. Less heat means way less of that weird sensor noise in long exposures. Stacking can't always fix that kind of internal junk. A single clean shot from a happy, cold sensor beats a stack from a warm one any day.

Wasn't there a study about how low humidity cuts down on that hazy glow? Your Sedona night must have been crazy clear.
