V marci tohto roku som fotil zn\u00e1mu otvoren\u00fa hviezdokopu M 45 – Plej\u00e1dy, alebo tie\u017e zn\u00e1mu aj ako hviezdokopa Sedeme sestier.

Ke\u010f\u017ee v marci som mal na hviezdokopu menej \u010dasu, rozhodol som sa ju znovu odfoti\u0165 teraz v novembri s t\u00fdm, \u017ee jej venujem cel\u00fa noc.<\/p>\n\n\n\n

Rozdiel medzi p\u00f4vodnou a touto verziu je v \u010dase integr\u00e1cie. Pokia\u013e prv\u00e1 verzia bola sn\u00edman\u00e1 iba 1 hodinu a 36 min\u00fat, tak druh\u00e1 verzia bola sn\u00edman\u00e1 u\u017e cel\u00fa noc s v\u00fdslednou dobou integr\u00e1cie 8 hod\u00edn a 44 min\u00fat. Na tejto druhej verzie vidno aj viac detailov a detaily nie s\u00fa ovplyvnen\u00e9 \u0161umom, preto\u017ee sa zv\u00fd\u0161il aj pomer sign\u00e1lu ku \u0161umu (SNR – signal noise ratio). Pri prvej verzii vych\u00e1dza z hrub\u00fdch v\u00fdpo\u010dtov SNR 10 tak u\u017e pri druhej verzi je SNR 22. <\/p>\n\n\n\n

Na fotenie som pou\u017eil rovnak\u00fa techniku ako pri prvej verzii, tj. SW Quattro 150P f\/4 s komakoretorom a reduktorom 0.86x s v\u00fdslednou svetelnos\u0165ou f\/3.45, kamera ZWO ASI 533 MC Pro v kombin\u00e1cii s filtrom Optolong L-Pro.<\/p>\n\n\n\n

Ako vidno na prv\u00fd poh\u013ead, druh\u00e1 verzia s dlh\u0161ou dobou integr\u00e1cie zobrazuje viac detailov a menej \u0161umu.<\/p>\n","protected":false},"excerpt":{"rendered":"
