Description
AstroT is a high-efficiency companion app built specifically for serious astronomical observers and astrophotographers. We reject flashy, superficial visual effects and focus strictly on what matters in the field: accurate observation data, real-time astro-weather, and precision star-finding navigation.
Equipped with a catalog of nearly 10,000 celestial objects, science-based weather assessment, and a star chart supporting single-point alignment, AstroT lets you lock onto any target and navigate flawlessly via GOTO guidance. It's your ultimate digital assistant for dark-sky expeditions.
【 Astro-Weather Dashboard and Prediction 】 - Real-time Astro-Weather: Monitor cloud cover, seeing, transparency, humidity, temperature, dew point, and wind speed/direction, combining Open-Meteo and 7Timer! data sources. - Observation Score (0–100): Automatically evaluates atmospheric conditions into a single scientific score, telling you at a glance whether tonight is worth setting up your gear. - 3-Day Hourly Forecast: Visualizes the observation index trend hour by hour with an intuitive bar chart, so you can plan your session down to the best time window. - Smart Location Management: Automatic GPS positioning plus one-tap switching between saved Favorite Locations — perfect for scouting multiple dark-sky sites.
【 Celestial Events and Times 】 - Precise Astronomical Times: Calculates sunrise/sunset and the exact start/end of civil, nautical, and astronomical twilight for your exact coordinates. - Moon Phase Tracking: Moonrise/moonset times, illumination percentage, and dynamic moon phase icons updated for every location and date. - Galactic Core Forecast: Tracks the real-time altitude of the Galactic Core (Sagittarius A*) and predicts its optimal visibility window for Milky Way photography.
【 Deep-Sky Object Retrieval and Filtering 】 - 10K Object Catalog: A built-in database of deep-sky objects (DSOs), stars, and solar system planets. - Real-time Visibility Filter: Instantly hides anything currently below your local horizon, so every result on screen is actually observable right now. - Advanced Search and Sorting: Find targets instantly by catalog number, magnitude, or angular size. Smart fuzzy search works across Chinese, English, and scientific designations. - Custom Object Import: Manually enter Right Ascension (RA) and Declination (Dec) to add your own targets — ideal for comets, newly discovered objects, or personal projects.
【 Interactive Star Chart and GOTO Finder 】 - Dual Interaction Modes: Seamlessly switch between Sensor Mode (gyroscope-driven point-to-sky navigation) and Manual Mode (touch-drag panning). - Single-Point Alignment: Corrects hardware compass drift instantly — align on any known star to eliminate sensor bias and dramatically boost GOTO pointing accuracy. - Visual Customization: Adjust the limiting magnitude (star density) and Field of View (FOV) on the fly. Toggle constellation lines, labels, and the Milky Way band independently. - GOTO Navigation: Highlights your selected target directly on the chart with a live directional indicator, guiding your telescope or camera mount to dead center.
【 Optimized for the Field 】 - Smart Power-Saving: Automatically lowers sensor sampling and map refresh rates when the device is idle, preserving critical battery life during long observation sessions. - Screen Awake: Keeps the display active during star chart navigation so your alignment and GOTO target are never lost mid-session. - Persistent State: A robust cross-tab state preservation mechanism — your coordinates, alignment, and target selection survive switching between menus. - Pure Dark Mode: Every screen uses a carefully tuned low-light color palette designed to protect your dark adaptation and night vision throughout the night.
Recent changes: ・Added ad support with user privacy consent settings ・Added a timeline feature to the star chart for planning sky views at any future time ・Added horizon and compass direction indicators to the star chart ・Fixed an issue where added/edited/deleted favorite locations required an app restart to appear ・Improved stability when switching app language
