The Sony A7a III Super UV/IR-Cut is an astromodified version of the Sony A7 III, designed for advanced astrophotography. Standard cameras use a filter to block much of the red spectrum, matching human color perception in daylight, but this also blocks the crucial H-alpha emission line that reveals astronomical gas nebulae. With the Super UV/IR-Cut modification, the original filter is replaced by one that allows the full visible spectrum (400–700 nm) to reach the sensor, significantly increasing sensitivity to H-alpha and SII emissions while blocking unwanted ultraviolet and infrared light.
