✦ MIDPOINT OBSERVATORY
A little logic. A sky full of signals.

THE NIGHT SHIFT / BINARY SEARCH

Somewhere in the stars,
a signal is waiting.

Find it by halving the sky. Choose the middle star in the active range, then compare its frequency with your target.

HOW TO LISTEN

Half the sky. Twice as close.

1. Count the active stars. Click the middle one; use the left middle when there are two.
2. Compare the scanned frequency to the target. Search lower, search higher, or lock an exact match.
3. Repeat in the remaining range. Every correct decision removes half the possibilities.
