Read full description

Point your phone at the sky and know instantly what’s worth imaging. Deep Sky Scanner turns your device into an aiming tool for the Seestar S50, scanning your field of view and ranking every galaxy, cluster, and nebula by altitude, brightness, and how well it’ll actually fit your frame. No more guessing what’s up, no star-hopping, no wasted setup time on a target that’s too big or too faint for tonight’s sky. FEATURES • Live sky scan — see every object in view as you move your phone, tracked with full 3D orientation for steady accuracy even near the zenith • Ranked target lists — sorted by altitude trajectory, brightness, or best overall fit for your Seestar S50 • Frame-fit scoring — know before you start whether an object will actually fit the frame, not spill past the edges • Ascending/descending badges — see whether a target is climbing toward better altitude or already past its peak • Planning mode — drag the time slider to preview the sky at any hour and plan your session in advance • Per-object imaging notes — integration-time guidance by magnitude, edge-on galaxy detection, and nearby-companion flags • Full OpenNGC catalog with offline fallback — works even without a signal • Additional catalogs are available and can be optionally selected on the settings page • Supports the Seestar family of telescopes Built by a Seestar owner, for Seestar owners.
