My Story

I'm Rey, and I’ve always been obsessed with astrophotography. In 2021, I stumbled into the thrilling world of aircraft transits—those split-second moments when a plane passes directly in front of the Sun or Moon. I started chasing those shots manually, scanning the skies and tracking planes with whatever tools I had, hoping to catch that perfect silhouette.

Back then, I was recording flight paths, times, and trajectories manually—no automation, just passion. Over time, I accumulated enough data to reverse-engineer the geometry behind these events. That research laid the groundwork for what would become this app.

Mission

Transit photography can be both beautiful and brutally time-sensitive. My goal is to simplify the process and help others get that rare, perfectly aligned shot without spending hours doing manual tracking or guesswork. The app combines real-time flight data with precise celestial calculations to forecast potential transits, with adjustable detection margins and predictive logic to suit every skill level—from casual spotters to hardcore photographers.

Our Journey

It started as a bunch of equations and rough sketches in a notebook. With help of real-world testing, those early formulas evolved into the fully interactive web app you see today. Each feature—whether it’s margin tuning, API switching, or new modes like Plane-on-Plane or Contrail alignment—comes from personal experience and user feedback. I use the app every day and continuously improve it based on real-world tests and community suggestions.
