Eighteen Hundred Spectra and Not One Photograph of the Sun

Spectroheliography

A good session leaves me with 1,800 spectra and zero photographs of the Sun. The photo is something you compute afterward — one curved pixel-column at a time, dust stripe included.

One Wavelength at a Time: Pipelines That Filter Light

Message-passing pipelines 🔗 Spectroheliography

A spectroheliograph builds a photo of the sun in a single colour by scanning it strip by strip — which is just a filtering pipeline made of brass and gears.

game

🎮 Slit & Sweep Drag a spectroheliograph slit across the Sun at a steady pace, switching wavelengths to reveal hidden features before the seeing fails.
