!!better!! Download Sequator

For many, the story ends at 3:00 AM, hunched over a laptop. You load your "light frames" (the photos of the sky) and maybe some "dark frames" (photos taken with the lens cap on to map sensor heat). You click "Start," and suddenly, the grainy gray mess transforms into a vibrant, high-definition window into the cosmos.

Double-click and select all your light frames (the photos of the stars).

Sequator requires a "stack" of images.
