Python for Astronomy: Calculating Optimal Sky Viewing Conditions

Have you ever wondered when a planet or star will be perfectly positioned in the night sky for observation? Python makes it easy to calculate exact celestial coordinates, rise and set times, and atmospheric viewing conditions without relying on third-party apps. This text-based course guides you through writing clean, modern Python scripts to automate astronomical calculations, helping you plan perfect stargazing sessions from scratch. You will learn to: — Understand foundational astronomical coordinate systems, altitude, and azimuth definitions; — Calculate rise, set, and transit times for planets and stars using Python; — Analyze atmospheric interference and airmass to determine optimal viewing windows; — Implement modern Python libraries such as Astropy and Skyfield for high-precision calculations; — Structure astronomy data cleanly using modern Python dataclasses and type hints; — Write reusable scripts to automate celestial event planning and custom observation alerts. You will start with the essential terminology of observational astronomy before moving on to hands-on written walkthroughs that calculate real-time positions and visibility conditions for any location on Earth. This course is designed for beginner Python programmers, amateur astronomers, and hobbyists looking to combine coding with stargazing, with no advanced physics background required.
