This page describes an image Perseids 2020 over Dark Sky Park Poloniny, by Tomáš Slovinský, Slovakia

Second place in the 2021 IAU OAE Astrophotography Contest, category Meteor showers.
A meteor shower occurs when the debris originated from comets or, on rare occasions, from asteroids enter the Earth’s atmosphere at high speed, leaving behind beautiful tracks in the sky due to friction with the atmosphere. This all-sky image taken in Slovakia in 2020 shows the Perseid meteor shower in a vivid way so one can really see the Perseids appearing all over the sky. This meteor shower is named so because the radiant point (the point on the sky where the meteors misleadingly seem to originate from) of the Perseid meteor shower is located in the constellation Perseus. This is a very prolific meteor shower, and a very popular phenomenon that can be observed from mid-July until mid-August, when the peak of activity happens. This is associated with the comet 109P/Swift–Tuttle, as Earth's orbit around the Sun crosses the debris left behind by this comet. This kind of image is very useful for full dome projections in planetariums, beautifully showing the Milky Way, our home Galaxy.

Image caption: Secondo posto al Concorso Astrofotografico IAU OAE 2021, categoria Piogge meteoriche.
Una pioggia di meteore si verifica quando i detriti originati da comete o, in rare occasioni, da asteroidi entrano nell'atmosfera terrestre ad alta velocità, lasciando dietro di sé bellissime tracce nel cielo a causa dell'attrito con l'atmosfera. Questa immagine a tutto cielo, scattata in Slovacchia nel 2020, mostra lo sciame meteorico delle Perseidi in modo vivido, cosicché si possano vedere davvero le Perseidi apparire ovunque nel cielo. Tale pioggia di meteore é definita così in quanto il punto radiante (il punto del cielo da cui le meteore sembrano provenire) della pioggia di meteore Perseidi si trova nella costellazione di Perseo. Si tratta di una pioggia di meteore molto prolifica e di un fenomeno molto popolare, che può essere osservato da metà luglio a metà agosto, quando si verifica il picco di attività. È associato alla cometa 109P/Swift-Tuttle, poiché l'orbita della Terra intorno al Sole attraversa i detriti lasciati da questa cometa. Questo tipo di immagine è molto utile per le proiezioni a tutta cupola nei planetari, in quanto mostra magnificamente la Via Lattea, la nostra galassia.

Image caption: 2021 年国际天文学联合会 OAE 天文摄影比赛流星雨类第二名。
当彗星或极少数情况下小行星产生的碎片高速进入地球大气层时，就会发生流星雨，它们是碎片与大气层摩擦后在天空中留下的美丽轨迹。这张于2020 年在斯洛伐克拍摄的全景天空图像生动地展示了英仙座流星雨，让人可以清晰地看到流星在天空各处划过。这个流星雨之所以被命名为英仙座流星雨，是因为它的辐射点（流星被误认为是从天空中某一点发射的）位于英仙座。这是一个非常活跃的流星雨，也是一个非常受欢迎的天文现象，从7月中旬到8月中旬都可以观测到，这段时间是此流星雨活动的高峰期。英仙座流星雨与彗星109P/Swift-Tuttle有关，因为地球绕太阳运行的轨道会穿过这颗彗星留下的碎片。这种图像非常适合用于天文馆的穹顶投影，可以完美地展示银河系——我们的家园星系。
