Most hot pixels are corrected by "dark frame subtraction"—taking a photo with the lens cap on and subtracting the noise. But DASS-102 defies this logic. Due to a physical defect likely caused by a microscopic lattice dislocation in the silicon (aggravated by cosmic ray damage or a manufacturing void), its signal isn't linear. It doesn't add noise; it creates a singularity . When you try to calibrate it out, the pixel value flips to absolute zero or wraps around to negative values, creating a black hole in your data where there should be a star.
In the end, DASS-102 is a reminder that in digital imaging, perfection is a lie. Some pixels just want to watch the world burn... at 15,000 electrons per second. dass102 hot
