Srpnov\u00fd nov byl ji\u017e minulost\u00ed a bl\u00ed\u017eilo se maximum roje Perseid. Nejvy\u0161\u0161\u00ed \u010das vyrazit pozorovat pod no\u010dn\u00ed oblohu. Relativn\u011b slu\u0161n\u00e9 podm\u00ednky slibovala st\u0159eda 11. 8. 2021…<\/p>\n

P\u016fvodn\u011b jsem cht\u011bl vyrazit do oblasti De\u0161tn\u00e9ho v Orlick\u00fdch hor\u00e1ch (\u0160ediviny nebo Jedlov\u00e1), ale Martin Myslivec na astro-f\u00f3ru napsal o \u00famyslu jet na Mezivr\u0161\u00ed. Nov\u011b je zde vyjedn\u00e1n p\u0159\u00edstup na plochu parkovi\u0161t\u011b a Martin jej za oblast Hradce Kr\u00e1lov\u00e9 za\u0161ti\u0165uje (dal\u0161\u00ed kl\u00ed\u010d m\u00e1 Kamil Fry\u0161 z Chocn\u011b). Nebylo co \u0159e\u0161it, Mezivr\u0161\u00ed je p\u0159eci jen tmav\u0161\u00ed m\u00edsto.<\/p>\n

Kdy\u017e jsem se ve\u010der kolem 21. hodiny bl\u00ed\u017eil na m\u00edsto, na z\u00e1pad\u011b mi ud\u011blal radost tenk\u00fd srpek M\u011bs\u00edce a kousek pod n\u00edm jasn\u00e1 Venu\u0161e. Na parkovi\u0161ti u\u017e techniku vybaloval Martin Myslivec<\/a> a Sl\u00e1vek Mach\u00e1\u010dek mj. dal\u0161\u00ed v\u00fdborn\u00fd fotograf<\/a>. Pozd\u011bji je\u0161t\u011b dorazili Martin Weszter z Pardubic a Jirka Mr\u00e1zek ze \u017damberka. Bylo n\u00e1s tedy p\u011bt a spousta r\u016fzn\u00e9 techniky. Pozorov\u00e1n\u00ed zaji\u0161\u0165ovaly t\u0159i dobsony a nav\u00edc Martin Weszter vzal velk\u00fd binokul\u00e1r TS 20×80 s mo\u017enost\u00ed pou\u017eit\u00ed UHC filtru. Krom\u011b m\u00e9ho dobsonu s pr\u016fm\u011brem 400 mm, Martin Myslivec p\u0159ivezl dal\u0161\u00ed \u010dty\u0159stovku, tentokr\u00e1t od SkyWatcher a nav\u00edc s GoTo. Po t\u00e9 co ji pro jednoho kolegu opravoval, provedl ten ve\u010der ostr\u00fd test. Je to ob\u0159\u00ed kus “n\u00e1bytku”. Je\u0161t\u011b\u017ee m\u011bl dod\u00e1vku a dal\u0161\u00ed p\u00e1r rukou k dispozici na slo\u017een\u00ed. T\u0159et\u00ed dobson byla moje b\u00fdval\u00e1 300 z d\u00edlny Libora N\u011bmce (Elbi). Jirka Mr\u00e1zek ji ale dop\u0159\u00e1l dal\u0161\u00edch vylep\u0161en\u00ed, nechal nov\u011b pokovit zrcadlo a aktivn\u011b pou\u017e\u00edv\u00e1 poncetovu plo\u0161inu a tak\u00e9 velkou 2″ binohlavu. Fotografick\u00e9 techniky bylo je\u0161t\u011b v\u00edc. Martin Myslivec sn\u00edmal Canonem 6D na kompaktn\u00edm AstroTracu TT320X-AG. Sl\u00e1vek provozoval dokonce dv\u011b sestavy. Jeden Pentax um\u00edstil na t\u011b\u017ekou mont\u00e1\u017e EQ6 a druh\u00fd na cestovn\u00ed SW Star Adventurer. Jirka sv\u016fj Olympus na\u0161rouboval na NanoTracker. V\u0161echny tyto uveden\u00e9 apar\u00e1ty se sna\u017eily zachytit padaj\u00edc\u00ed meteory. Martin Weszter svoji sestavu dalekohledu ED 80, kamery, point\u00e9ru a mont\u00e1\u017ee iOptron CEM40 nam\u00ed\u0159il na galaxii M31.<\/p>\n

Bohu\u017eel po\u010das\u00ed nebylo \u00fapln\u011b ide\u00e1ln\u00ed, podm\u00ednky trefn\u011b popsal Martin Myslivec na astrof\u00f3ru<\/a>. J\u00e1 si p\u0159ipravil k pozorov\u00e1n\u00ed aktu\u00e1ln\u00ed seznam jasn\u011bj\u0161\u00edch komet, a p\u00e1r drobnost\u00ed k tomu. Bohu\u017eel Stellarium v m\u00e9m notebooku vy\u017eadovalo pro najit\u00ed blazaru BL Lac (na jeho\u017e zjasn\u011bn\u00ed n\u00e1s na setk\u00e1n\u00ed upozornil Milo\u0161 Bo\u010dek) p\u0159ipojen\u00ed k internetu a tak jsem toto pozorov\u00e1n\u00ed neuskute\u010dnil. To sam\u00e9 bylo s aktu\u00e1ln\u00edm zjasn\u011bn\u00edm novy RS Oph. Komety se mi tentokr\u00e1t z velk\u00e9 \u010d\u00e1sti da\u0159ilo pozorovat. Ve 22:45 jsem zaznamenal prvn\u00ed C\/2020 PV6 PANSTARRS<\/a> v souhv\u011bzd\u00ed Herkula (cca 14 mag), o p\u016flnoci dal\u0161\u00ed PANSTARRSku C\/2017 K2<\/a> tak\u00e9 v Herkulu (cca 13 mag), v 1:53 kr\u00e1toperiodickou 67P\/\u010curjumov-Gerasimenkov\u00e1<\/a> v Ryb\u00e1ch (cca 13,5 mag), v 2:05 4P\/Faye<\/a> v B\u00fdku\u00a0 (cca 11,5 mag) a v \u010dase 2:40 C\/2019 L3 ATLAS<\/a> ve Vozkovi (cca 11,5 mag). R\u00e1no u\u017e jsem nedok\u00e1zal detekovat 15P\/Finlay<\/a>.<\/p>\n

Po t\u00e9 co Martin Myslivec p\u0159ekonal po\u010d\u00e1te\u010dn\u00ed probl\u00e9my s ustaven\u00edm GoTo dobsona, za\u010dal n\u00e1s z\u00e1sobovat nev\u0161edn\u00edmi v\u00fdhledy na zn\u00e1m\u00e9 DSO. Jeliko\u017e v jeho z\u00e1zra\u010dn\u00e9m kuf\u0159\u00edku m\u00e1 vesm\u011bs \u0161pi\u010dkov\u00e9 p\u0159\u00edslu\u0161enstv\u00ed, pohled nap\u0159\u00edklad na \u0158asy v 31 mm Nagleru s OIII filtrem (a samoz\u0159ejm\u011b koma-korektorem) byl \u00fa\u017easn\u00fd. Takov\u00fdch objekt\u016f byla cel\u00e1 \u0159ada. Martin ne\u00fanavn\u011b sypal do ru\u010dky dalekohledu dal\u0161\u00ed po\u017eadavky a syst\u00e9m GoTo je state\u010dn\u011b plnil. Snad se tedy oprava ovl\u00e1d\u00e1n\u00ed zda\u0159ila. Jedn\u00edm z vrchol\u016f bylo pozorov\u00e1n\u00ed planet. Martin vsunul do v\u00fdtahov\u00e9 \u0161achty 4 mm Naglera, kter\u00fd d\u00e1val zv\u011bt\u0161en\u00ed 450x. P\u0159i tomto velk\u00e9 zv\u011bt\u0161en\u00ed spolehliv\u011b tracking dalekohledu udr\u017eel planety Jupiter a Saturn v zorn\u00e9m poli. Velk\u00e1 v\u00fdhoda poh\u00e1n\u011bn\u00e9ho dobsonu a velk\u00e1 par\u00e1da. Seeing byl velmi slu\u0161n\u00fd. Martin jen litoval, \u017ee doma zapomn\u011bl ADC. P\u0159eci jen p\u0159i tomto zv\u011bt\u0161en\u00ed byly znateln\u00e9 barevn\u00e9 lemy. Velmi p\u011bkn\u00e9 byly planety tak\u00e9 v Jirkov\u011b t\u0159\u00edstovce, binohlava m\u00e1 svoje kouzlo, by\u0165 zv\u011bt\u0161en\u00ed u\u017e nebylo tak velk\u00e9.\u00a0 Kdo cht\u011bl otestovat pevnost sv\u00fdch rukou, mohl vyu\u017e\u00edt bezm\u00e1la 2,5 kg binokul\u00e1r 20×80. Odm\u011bnou mu byly kr\u00e1sn\u00e9 p\u0159ehl\u00eddky Ml\u00e9\u010dn\u00e9 dr\u00e1hy a jasn\u011bj\u0161\u00edch DSO.<\/p>\n

A samoz\u0159ejm\u011b i meteory l\u00e9taly, p\u0159esto\u017ee maximum roje Perseid byl a\u017e n\u00e1sleduj\u00edc\u00ed noc. V\u011bt\u0161inou v\u0161ak m\u00e9n\u011b jasn\u00e9. Snad se n\u011bjak\u00e9 poda\u0159ilo zaznamenat pracuj\u00edc\u00ed technikou. Spadl v\u0161ak jeden kr\u00e1sn\u00fd bolid v \u010dase 1:18, jeho\u017e stopa byla patrn\u00e1 i n\u011bjakou dobu pro pr\u016fletu. Prom\u00edtal se n\u00e1m n\u00edzko severn\u00edm sm\u011brem do souhv\u011bzd\u00ed Velk\u00e9 medv\u011bdice. Na tento sm\u011br v\u0161ak objektivy nem\u00ed\u0159ily, tak z\u016fstal pravd\u011bpodobn\u011b nezaznamen\u00e1n. Perseidu zaznamenal Jirka Mr\u00e1zek hned z kraje noci a fotku mi pro tento \u010dl\u00e1nek laskav\u011b poskytl. Bohu\u017eel to nen\u00ed ta jasn\u00e1 stopa (z\u00e1blesk dru\u017eice?), ale najdete ji v Ml\u00e9\u010dn\u00e9 dr\u00e1ze. T\u00edm bych mu cht\u011bl, jako\u017eto i v\u0161em ostatn\u00edm, za p\u0159\u00edjemn\u011b str\u00e1venou noc pod\u011bkovat.<\/p>\n
