About this app
StarMag turns two magnitudes into a brightness ratio, then solves distance modulus and combined light for the same comparison.
What it helps with
- Apparent versus absolute magnitude and the inverted scale (smaller number, brighter star).
- Flux ratio that names which source is brighter, not a bare factor.
- Distance modulus in parsecs and light-years, solved for any one of the three terms.
- Combined magnitude for two to eight sources.
- Star presets from the Sun to Pluto, plus typical instrument reach.
