## Description

Mobile Observatory is a feature-rich astronomy app that renders a photorealistic sky and uses real topographic horizon data to compute accurate rise and set times for your exact location. With a 3D terrain profile built from NASA elevation data, you can plan astrophotography shots and observe celestial events as they truly appear from your surroundings.

Key features include real-time alerts for auroras and solar activity, ISS visibility with trajectory predictions, a comprehensive observing planner tailored to your gear, and up-to-date catalogs of minor planets, comets, and satellites. The app also integrates telescope control, deep sky catalogs, and a live space weather dashboard, enabling precise, repeatable observing sessions.

## Review summary

Mobile Observatory Astronomy is praised for its rich and comprehensive astronomy data, realistic night sky visuals, and user-friendly features catering to amateurs and enthusiasts alike. Users appreciate its detailed celestial object database and event planning tools. However, multiple reviews mention problems with star glare, sky chart drift, and VR mode difficulties. Some catalogs are incomplete for advanced querying, and the night vision mode is criticized for being too dark. Occasional issues with notifications and ISS tracking were also noted, but the developer is responsive and updates the app regularly.
