Details:
It took almost 2 years of work, almost 450 hours of postprocessing and many hours of other hard work, but it was worth it. In attached images (annotated and clear) you can count 407 Perseid meteors captured during 8 nights (51 hours total) and registered to full-night panorama of sky taken during peak of Perseids in 2018 over Kolonica Observatory, Slovakia. Data were calibrated, color corrected and precisely photometrically added to the mosaic so the viewer could better understand some specifications of the most popular annual meteor shower. Thus you can discuss movement of radiant in the sky along with increasing activity of the shower, distribution of the meteors (real and also with selection effect - which part of the sky is mostly above horizon during Perseid nights), distribution of their brightness (were taken during moonless nights and about 70 percents of them in dark sky) and also colors caused by emissions of elements in meteoroids or our atmosphere. Discussion can go much further, so much more you can find here: https://www.astronom.cz/horalek/?p=6509
For sky mosaic used Canon 6D BCF modified, Samyang 12 mm, f3.5, ISO 2000, 7 images (each 22x120s stacked, darkframes applied) stitched together, tracked on Vixen GP2 mount. Meteors were captured with 2 Canon 6D cameras, both with 12mm lens (to cover whole sky), f2.8, ISO 10000, 30s exposures, timelapsing from tripods.
