Astronomy Imaging: Diffraction Limit & Exposure Stacking (2D)

2D astronomy-imaging lab: switch between Hubble, JWST, Chandra and EHT, watch the Rayleigh diffraction limit set what each instrument can resolve, then stack exposures to climb the SNR.

This 2D companion drives the same Rayleigh diffraction-limit and exposure-stacking formulas as the 3D version through a plain canvas view built for reading the physics directly: switch the instrument to watch a fixed-separation pair of test points split apart or blur into one blob exactly as θ = 1.22λ/D predicts for Hubble's 2.4 m mirror, JWST's 6.5 m segmented mirror, Chandra's X-ray optics and the Event Horizon Telescope's Earth-sized virtual dish, while the stacked-exposures, gain and denoise sliders drive a live sensor-noise overlay and an SNR readout that climbs as √N with every doubling of stacked frames.

⚙ Under the hood

2D astronomy-imaging lab: switch between Hubble, JWST, Chandra and EHT to see how aperture and wavelength set the Rayleigh diffraction limit, then stack exposures to watch signal-to-noise climb out of sensor noise.
