Why StarScope
AAVSO and the BAA do outstanding scientific work, but they are built around membership organisations, English-speaking communities, and legacy interfaces. StarScope is free at its core, mobile-first, and built for true hemisphere parity from day one — Southern observers get first-class tools, not a Northern feed with a flag.
