§ A · AtmosBird Sky camera · 140° fisheye
One photo of the
sky, every ten minutes.
A 140° fisheye on the roof photographs the sky every ten minutes. At night the frames are analysed for striking objects: ISS passes, the moon, meteors, sometimes an aircraft or a distant strip of thunderstorm. Most of it is clouds, and clouds are fine too.
§ A-02 · Today in frames Twelve moments, every two hours
Clear morning,
cloudy afternoon.
The camera takes 144 photos a day. Below is one snapshot every second hour. Dots on a night frame are stars or a meteor; the half circle at the bottom is the moon.

§ A-03 · Interesting finds What the analysis noticed this month
ISS, meteors,
a forgotten aircraft.
An analysis script compares frames with the previous one and flags movements, lines or objects that don't match the star chart. Anything striking ends up here.

§ A-05 · Under the hood How AtmosBird is set up
A ZWO ASI camera with a 2.5mm fisheye lens looks straight up from the roof. The Raspberry Pi grabs a frame every ten minutes and sends it to the NAS. At night a script runs that compares consecutive frames for differences, checks them against a star chart, and flags anything that moves or doesn't match the stars as "possibly interesting". After that I look it over by hand before I stick a name on it.
