AstraStack is an easy to use application used to stack videos or images of planets, the sun, moon, deep sky objects and more. Stacking is a technique used to improve the quality of the image by aligning each frame and then averaging the best frames to create a low noise version of the image which can then be sharpened.
Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
