Za\u010d\u00e1tkem b\u0159ezna 2021 bylo n\u011bkolik jasn\u00fdch ve\u010der\u016f, kter\u00e9 jsem necht\u011bl po pom\u011brn\u011b zata\u017een\u00e9m \u00fanoru prome\u0161kat. M\u011bs\u00edc byl v \u00fapl\u0148ku 27. 2. a tak p\u0159estal z ve\u010dera sv\u00fdm svitem ru\u0161it. Bohu\u017eel vstoupila v \u00fa\u010dinnost nov\u00e1 vl\u00e1dn\u00ed opat\u0159en\u00ed, kter\u00e1 zna\u010dn\u011b omezila cestov\u00e1n\u00ed za tmou. Musel jsem vz\u00edt za vd\u011bk relativn\u011b slu\u0161n\u00fdm m\u00edstem v r\u00e1mci na\u0161eho katastru obce \u010cernilov a t\u00edm je Traneck\u00fd kopec, m\u00edstn\u00ed znaj\u00ed t\u00e9\u017e ozna\u010den\u00ed Pultrova cesta. Vlastn\u00edm jasom\u011br od firmy Unihedron<\/a>, konkr\u00e9tn\u011b verzi s optikou tzv. SQM-L. Provedl jsem m\u011b\u0159en\u00ed a zapsal do datab\u00e1ze na str\u00e1nk\u00e1ch skyquality.cz<\/a>. V\u00fdsledek nep\u0159ekvap\u00ed, Orlick\u00e9 hory to zdaleka nejsou, ale obloha je pou\u017eiteln\u00e1 (by\u0165 m\u00e1 sv\u00e9 limity, kter\u00e9 se uk\u00e1zaly). Sm\u011br Hradec Kr\u00e1lov\u00e9 je samoz\u0159ejm\u011b minim\u00e1ln\u011b do 50\u00b0 nad obzor katastrofa.<\/p>\n

M\u016fj hlavn\u00ed dalekohled je tzv. dobson 16″ f\/4,5 <\/a>(pr\u016fm\u011br 406mm, ohnisko 1826mm) firmy Explore Scientific. Je to \u010d\u00ednsk\u00fd v\u00fdrobek, kvalita zpracov\u00e1n\u00ed by mohla b\u00fdt lep\u0161\u00ed, ale koncept slo\u017een\u00ed pro p\u0159evoz se mi l\u00edb\u00ed. Doma jsem ud\u011blal n\u011bkolik vylep\u0161en\u00ed a moment\u00e1ln\u011b jsem spokojen. M\u00e1m jej asi 1 rok.<\/p>\n

Ve\u010der 1. b\u0159ezna 2021: v tento den prol\u00e9tal bl\u00edzkozemn\u00ed asteroid 1999 RM45<\/a> mimo jin\u00e9 souhv\u011bzd\u00edm Jednoro\u017ece. A\u010dkoliv jasnost nebyla nijak velk\u00e1 cca 13,7 mag, nep\u0159edstavovala probl\u00e9m. \u00da\u017easn\u00fd byl znateln\u00fd pohyb v hv\u011bzdn\u00e9m poli. Na youtube jsem objevil dv\u011b p\u011bkn\u00e1 videa – simulaci pr\u016fletu<\/a> a z\u00e1znam \u010d\u00e1sti pr\u016fletu<\/a>. Tento ve\u010der byla velik\u00e1 vlhkost ve vzduchu a teplota t\u011bsn\u011b nad nulou, v\u0161e se zna\u010dn\u011b rosilo. Stihnul jsem jen \u00fasp\u011b\u0161n\u011b pozorovat otev\u0159en\u00e9 hv\u011bzdokupy NGC 381<\/a> a NGC 1907<\/a> a ne\u00fasp\u011b\u0161n\u011b kometku C\/2021 A4 NEOWISE<\/a>.<\/p>\n

Ve\u010der 5. b\u0159ezna 2021: hlavn\u00edm c\u00edlem byla nov\u00e1 kometa C\/2021 D1 SWAN<\/a>. Po z\u00e1padu Slunce byla jen nevysoko nad z\u00e1padn\u00edm obzorem v souhv\u011bzd\u00ed Pegase. V cca 19:10 se mi ji poda\u0159ilo detekovat p\u0159i pou\u017eit\u00ed zv\u011bt\u0161en\u00ed 200x. Nebyla p\u0159\u00edli\u0161 v\u00fdrazn\u00e1, dif\u00fazn\u00ed bez centr\u00e1ln\u00ed kondenzace a pom\u011brn\u011b velk\u00e1 s odhadovanou jasnost\u00ed kolem 12,5 magnitudy. Dal\u0161\u00edm c\u00edlem byla kometa C\/2019 L3 ATLAS<\/a>. Toho \u010dasu kr\u00e1sn\u011b vysoko v Kasiopei a nedaleko kr\u00e1sn\u00e9 planet\u00e1rky M 76<\/a> “Mal\u00e1 \u010dinka”. Tato kometka je pom\u011brn\u011b mal\u00e1, kondenzovan\u00e1 “kuli\u010dka” cca 13 mag, nicm\u00e9n\u011b zjas\u0148uje a zjas\u0148ovat bude.\u00a0 V\u011b\u0159\u00edm, \u017ee si je\u0161t\u011b dlouho u\u017eijeme. Bohu\u017eel jsem si vyl\u00e1mal zuby op\u011bt na C\/2021 A4 (nedaleko Hy\u00e1d) a 141P\/Machholz<\/a> v Orionu. Tady se bohu\u017eel projevilo, \u017ee obloha v t\u011bchto sm\u011brech je u\u017e p\u0159\u00edli\u0161 sv\u011btl\u00e1. Pot\u011b\u0161il Mars, kter\u00fd je u\u017e v\u0161ak docela daleko a kotou\u010dek se oproti opozici znateln\u011b zmen\u0161il. Tento ve\u010der zlobila obla\u010dnost jdouc\u00ed od severu a tak se muselo trochu lovit mezi mraky.<\/p>\n

Ve\u010der 7. b\u0159ezna 2021: nejlep\u0161\u00ed podm\u00ednky, bezv\u011bt\u0159\u00ed, jasno a -3\u00b0C. Dopl\u0148oval jsem z\u00e1znamy pozorovan\u00fdch jasn\u011bj\u0161\u00edch objekt\u016f z katalog\u016f NGC a IC. Krom\u011b otev\u0159en\u00fdch hv\u011bzdokup NGC 436<\/a>, NGC 1502<\/a>, NGC 1981<\/a>, NGC 2126<\/a> do\u0161lo i na planet\u00e1rn\u00ed mlhoviny. Na n\u011b s oblibou pou\u017e\u00edv\u00e1m \u0161pi\u010dkov\u00fd filtr OIII zna\u010dky Lumicon. Bezvadn\u011b na n\u011b funguje. Prvn\u00ed byla NGC 1501 <\/a>(Camel\u00b4s Eye Nebula nebo tak\u00e9 Oyster Nebula) v \u017diraf\u011b, d\u00e1le IC 418<\/a> (Spirograph Nebula) v Zaj\u00edci a na z\u00e1v\u011br mal\u00e1 IC 2149<\/a> ve Vozkovi. Tentokr\u00e1t jsem tak\u00e9 v\u00edce p\u00e1tral v souhv\u011bzd\u00ed Oriona, kter\u00e9 je na mlhoviny nesm\u00edrn\u011b bohat\u00e9. Ka\u017ed\u00fd zn\u00e1 M42 a M43, ale mimo tyto se zde nach\u00e1z\u00ed nap\u0159. B\u011b\u017e\u00edc\u00ed mu\u017e (Running Man) SH 2-279<\/a>, reflexn\u00ed NGC 1999<\/a> (13th Pearl Nebula) a dal\u0161\u00ed. St\u00e1le mi unik\u00e1 zn\u00e1m\u00e1 Ko\u0148sk\u00e1 hlava B33<\/a> nebo nedaleko v Eridanu NGC 1909<\/a> Hlava \u010darod\u011bjnice, ale to by cht\u011blo opravdu dobrou oblohu. A ta u Hradce nen\u00ed. Alespo\u0148 se m\u00e1m na co t\u011b\u0161it.<\/p>\n","protected":false},"excerpt":{"rendered":"
