Deep Sky Object Finder vs Deep Sky Scanner

Deep Sky Object Finder turns your iPhone or iPad into an interactive map of the sky. Move your device to explore the sky in real time using its heading and elevation sensors. Identify visible stars, planets, the Sun, the Moon, constellations, and deep-sky objects. You can also browse manually, zoom in for a closer look, or search for a specific object and center it on the display. Features include: - Live sky tracking using device orientation - Stars above and below the horizon - Planets, the Sun, and the Moon with lunar phases - Messier deep-sky objects - Constellation lines, names, illustrations, and descriptions - Tap objects and constellation names for additional information - Links to relevant Wikipedia articles - Search and automatic object centering - Adjustable observation time for planning later in the day or night - Pinch-to-zoom and manual sky navigation - Optional camera-assisted aiming view - Right ascension and declination grid - Horizon and ecliptic overlays - Configurable display options - Offline sky-map operation after installation Whether you are learning the constellations, looking for a planet, or planning an evening under the stars, Deep Sky Object Finder helps you understand what is in the sky and where to find it. Location and motion access are used to align the sky map with your surroundings. Camera access is optional and is used only when you enable the camera-assisted aiming view.

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.
