By the end
What you'll build
- Solve NSEA-grade positional astronomy problems — pole altitudes, culminations, circumpolar limits, sidereal time and hour angle — with fast diagram-first methods
- Apply Kepler's laws, vis-viva, orbital energy and Hohmann-transfer reasoning to celestial mechanics numericals, and verify hand solutions in Python
- Compute telescope magnification, focal ratio, light grasp, exit pupil and diffraction-limited resolution, and know when the atmosphere takes over
- Use the magnitude system, distance modulus, parallax, Wien's law and Stefan-Boltzmann to reason quantitatively about stars
- Sit a full NSEA-pattern timed mock at authentic pace and read the result honestly against the NSEA → INAO → OCSC → IOAA pipeline
