Deep Sky Scanner turns your phone into an aiming tool — scan the sky, and get a ranked list of galaxies, clusters, and nebulae scored for altitude, brightness, and how well they'll actually fit your Seestar's frame.
No star-hopping, no guessing what's up. Scan the patch of sky your Seestar can actually see, and let the app do the sorting.
Hold your phone or iPad toward the sky. Full 3D orientation tracking reads your exact aim — steady even near the zenith, where ordinary compass apps lose their footing.
Every object within your field of view appears instantly, pulled from the full OpenNGC catalog with an offline fallback for nights without signal.
Targets are ranked by altitude trajectory, brightness, and Seestar frame fit — so the top of the list is genuinely worth your imaging time.
See at a glance whether a target is climbing toward better altitude or already past its peak for the night.
Objects are checked against the Seestar S50's actual field of view, so you're not left with a galaxy that spills off the edge.
Drag the time slider to preview the sky at any hour of the night and plan your session before you ever go outside.
Integration-time guidance by magnitude, edge-on galaxy detection, and nearby-companion flags for objects worth a wider frame.
Toggle between best overall, brightest, or nearest to where you're pointed — and hide anything that won't fit the Seestar's frame well, before you waste a night on it.
Deep Sky Scanner is heading to the App Store.
