Smartphone astro mode vs my old DSLR stack

I took 120 phone exposures on a tripod last weekend. My Canon 60D with 3 stacked 30-second frames looked way cleaner. Less noise, more color. Am I missing something with phone processing tricks?

Night sky is so tricky, my cat ran out once while I was setting up star photos.

Wait, are you stacking the phone shots in software or just looking at them as-is? Raw phone frames are way noisier than DSLR ones at the same exposure time. Your 60D has a bigger sensor and gathers way more light per pixel. Those 30 second DSLR frames are catching details that your phone needs 10x more frames to see. Phone astro modes usually do a lot of processing under the hood. They stack and align frames automatically, but they often oversmooth stuff and lose the faint stuff. Your DSLR stack probably has better dynamic range and less weird artifacts. You could try using a dedicated stacking app for the phone shots like DeepSkyCamera or something similar. But honestly? Your 60D is just a better tool for this job. The phone is fine for quick snapshots but it can't beat proper hardware. The phone manufacturers make big claims about their "night modes" but they can't cheat physics. Bigger sensor wins every time for astro work.
