Na p\u00e1tek 2. 9. slibovala p\u0159edpov\u011b\u010f n\u011bkolika model\u016f postupn\u00e9 vyjasn\u011bn\u00ed, a tak jsme se rozhodli vyrazit na h\u0159eben Orlick\u00fdch hor. Sice se M\u011bs\u00edc bl\u00ed\u017eil k prvn\u00ed \u010dtvrti, ale nach\u00e1zel se n\u00edzko nad obzorem a zapadal brzo, konkr\u00e9tn\u011b v 22:07.<\/p>\n

Na parkovi\u0161t\u011b pod Kom\u00e1\u0159\u00edm vrchem jsem dorazil chv\u00edli po p\u016fl dev\u00e1t\u00e9 a za\u010dal pomalu vybalovat techniku. Za chv\u00edli dorazil Martin Myslivec a odemkl br\u00e1nu. Postupn\u011b se sj\u00ed\u017ed\u011bli dal\u0161\u00ed \u00fa\u010dastn\u00edci. Bylo n\u00e1s nakonec \u0161est: j\u00e1, MMys, Martin Weszter, Lenka Rutteov\u00e1, Sl\u00e1vek Mach\u00e1\u010dek a Pavel Vel\u00ednsk\u00fd. Na place se se\u0161li dva 40cm dobsony, 20cm Cassegrain na iOptron CEM40 mont\u00e1\u017ei a nav\u00edc n\u011bkolik fotoapar\u00e1t\u016f na r\u016fzn\u00fdch mont\u00e1\u017e\u00edch fotilo. Obloha postupn\u011b tmavla. Hodnoty na\u0161ich jasom\u011br\u016f SQM-L se pohybovaly v rozmez\u00ed kolem 21,2 – 21,3 MSA. Tedy slu\u0161n\u00e9 hodnoty, ale \u0161pi\u010dka to nebyla. Ml\u00e9\u010dn\u00e1 dr\u00e1ha samoz\u0159ejm\u011b z\u00e1\u0159ila, je to velk\u00fd rozd\u00edl oproti dom\u00e1c\u00ed obloze v n\u00ed\u017ein\u011b u m\u011bst.<\/p>\n

Tentokr\u00e1t jsem ned\u011blal \u017e\u00e1dn\u00e9 n\u00e1ro\u010dn\u011bj\u0161\u00ed pozorov\u00e1n\u00ed, sp\u00ed\u0161e jsme proj\u00ed\u017ed\u011bli jasn\u00e9 DSO objekty. Mus\u00edm p\u0159iznat, \u017ee p\u0159es l\u00e9to jsem toho moc nenapozoroval a oko vypadlo z tr\u00e9ninku. Ani komety nemaj\u00ed te\u010f siln\u00e9 obdob\u00ed. Pozoroval jsem jen jednu C\/2022 E3 ZTF, kter\u00e1 by na za\u010d\u00e1tku roku 2023 mohla dos\u00e1hnout hranice viditelnosti i pouh\u00fdm okem. B\u011bhem noci moc nefoukalo a vlhkost byla\u00a0 vysok\u00e1. V\u0161e se zna\u010dn\u011b rosilo a znep\u0159\u00edjem\u0148ovalo pozorov\u00e1n\u00ed a focen\u00ed. Do pohotovosti se dostal f\u00e9n (12V) a vyh\u0159\u00edvac\u00ed p\u00e1sky.<\/p>\n

Planety te\u010f maj\u00ed dobr\u00e9 pozorovac\u00ed obdob\u00ed, tak nemohly uniknout na\u0161\u00ed pozornosti. Bohu\u017eel tolik pot\u0159ebn\u00fd seeing nep\u0159\u00e1l. Jeho slovn\u00ed hodnocen\u00ed by se dalo vyj\u00e1d\u0159it slovy jako \u0161patn\u00fd – mizern\u00fd – darebn\u00fd a\u017e katastrof\u00e1ln\u00ed. Hlavn\u011b v\u00a0 Cassegrainu jsme p\u0159esto pozorovali st\u00edn m\u011bs\u00edce Io na Jupiteru a pozd\u011bji i opu\u0161t\u011bn\u00ed samotn\u00e9ho Io prostoru p\u0159ed planetou. V MMysov\u011b dobsonu jsme pozd\u011bji vid\u011bli u kraje i velkou rudou skvrnu (GRS). Saturn nemohl nab\u00eddnout za t\u011bchto podm\u00ednek nic zaj\u00edmav\u00e9ho. Takt\u00e9\u017e Mars seeing nehezky “znetvo\u0159il”, doslova jakoby plaval v \u0159ece. O albedov\u00fdch \u00fatvarech nemohlo b\u00fdt \u0159e\u010di. Prohl\u00e9dli jsme si takt\u00e9\u017e kotou\u010dky planet Uran a Neptun.<\/p>\n

B\u011bhem noci pot\u011b\u0161ily prol\u00e9taj\u00edc\u00ed meteory a nebylo jich m\u00e1lo. Jeden opravdu p\u011bkn\u011b jasn\u00fd (bohu\u017eel kr\u00e1tk\u00fd) zaznamenal Sl\u00e1vek v \u010dase 22:44 na sv\u016fj Pentax. Prolet\u011bl souhv\u011bzd\u00edm Kozoroha. Nad severn\u00edm obzorem se objevilo tak\u00e9 sv\u011bteln\u00e9 z\u00e1\u0159en\u00ed atmosf\u00e9ry tzv. airglow, viditeln\u00e9 slab\u011b i pouh\u00fdma o\u010dima.<\/p>\n
