This multi-camera composite (pseudo all-sky) is far more than a simple photo mosaic: it unifies the entire night's meteor activity into a mathematically precise celestial projection. Alongside the prominent radiant of the Perseids, the accurate astrometric alignment clearly reveals weaker meteor streams, including the kappa Cygnids and the Antihelion complex.
Key Processing Highlights:
· Automated Masking & Hot-Pixel Correction: Defective pixels are reconstructed prior to reprojection, preventing false meteor streak artifacts.
· Photometric Normalization: Smooths out gradient differences caused by humidity and light pollution near field boundaries.
· Pseudo All-Sky Stacking: Combines camera coverage into a unified zenithal azimuthal-equidistant projection while preserving natural sky conditions.
