Stellaloom

Stellaloom is a personal astronomy studio. Pick any place and moment and it reconstructs the real sky — then lets you move through the night, see what was actually overhead, and keep it as a poster made to print. WATCH THE NIGHT MOVE Most star-map apps freeze one instant. Stellaloom animates the real motion of the sky across the whole night — stars wheeling overhead, the Moon rising, twilight fading — with a timeline you can scrub. Export it as a short video, not just a still. THE SKY, AS IT ACTUALLY LOOKED Stellaloom reconstructs the true conditions of your moment: the Moon's phase and position, which planets were up and where, the constellation riding highest, meteor activity, and even the archived cloud cover for that night and place. It will tell you honestly when the stars were hidden — and show what stood above the clouds.
