Orionids 2020 over Slovakian volcanoes<\/p><\/div>\n

Debris of Halley’s comet<\/a> enter our atmosphere every May and October, producing two annual meteor showers<\/a>. The October one, peaking usually around 21st October, is called Orionids<\/a>. In the view, you can count 19 of them seemingly flying from are above Orion constellation<\/a> (left from the center). The sky is crossed by the Milky Way, hosting also numerous red hydrogen nebulae<\/a> such as NGC 1499<\/a> called “California” (on the top) or many of them in the Orion itself<\/a>. Very bright is planet Mars, nearby the “Gegenschein<\/a>“, captured just a week after its great opposition in 2020<\/a>. In the foreground, five of Slovak extinct volcanoes north from Pre\u0161ov city<\/a> surrounded by fog can be seen (such as the light pollution<\/a> from the city itself). The closest one is the “Lys\u00e1 str\u00e1\u017e” mount, same as the others were active last time in the Tertiary Period<\/a> (Slovak study<\/a> says 13.1 million years), now giving a fantastic view from Ter\u0148a city.<\/p>\n

Captured from 19th to 23rd October 2020, for foreground used Canon 6D BCF modified, Sigma 35mm, f1.6, ISO 6400, panorama of 28 panels, each stacked of 6×13 seconds from tripod. Meteors captured by timelapsing with Canon 6D, Samyang 12mm, f 2.8, ISO 10000, 30s. Circumstances were very bad <\/strong> as the humidity was rising and the fog was developing on the photographic site during the imaging and so the image seems a bit “unclean”.<\/p>\n
