Lucky Imaging for Astrophotography |
updated: 2026-08-034 |
Lucky imaging (also called lucky exposures) is a form of speckle imaging used in astrophotography. Speckle imaging techniques use a video camera with exposure times short enough (100 ms or less) to keep changes in the Earth's atmosphere during the exposure as minimal.
Lucky imaging selects the optimal exposures that are least affected by the atmosphere (typically about 10%) and combines them into a single image by shifting and adding the short exposures, resulting in a much higher angular resolution than would be possible with a single, longer exposure that includes all the frames.
