Amalensi e-Telephoto, njengoba igama lisikisela, zinobude obude bokugxila futhi ngenxa yalokho zinendawo encane yokubuka, okwenza zifanelekele ukuthwebula izithombe zabantu abakude. Ngokuthwebula izithombe zezinkanyezi, amalensi e-telephoto ngokuvamile awafaneleki ukuthwebula isibhakabhaka sasebusuku, ikakhulukazi ezithombeni ezibanzi zezindawo ezinkulu zesibhakabhaka.
1.Imikhawulo yokusebenzisa amalensi e-telephoto ukuthwebula isibhakabhaka sasebusuku
I-Astrophotography ngokuvamile isebenzisa amalensi ane-wide-engela; uma kuqhathaniswa, amalensi e-telephoto anemikhawulo ebaluleke kakhulu lapho ethwebula izithombe zesibhakabhaka sasebusuku:
(1)Insimu encane yokubuka yenza kube nzima ukuthwebula isibhakabhaka sonke ebusuku
Amalensi e-Telephoto anensimu encane yokubuka, ngokuvamile angaphansi kuka-30°, futhi awakwazi ukuthwebula yonke i-Milky Way noma ububanzi obukhulu besibhakabhaka sasebusuku. Isibhakabhaka sasebusuku (njenge-Milky Way) sithatha indawo enkulu (enesikhala esivundlile esingaphezu kuka-100°).
Uma usebenzisa ilensi ye-telephoto, ungathwebula ingxenye yesibhakabhaka sasebusuku kuphela (njengeqoqo elincane lezinkanyezi noma inkanyezi eyodwa ekhanyayo), okwenza kube nzima ukukhombisa isimo esiphelele seMilky Way noma imizila yezinkanyezi emikhulu.
(2)Isikhathi esilinganiselwe sokuvezwa singabangela kalula ukuthi umuntu alandelele njengezinkanyezi
Ngenxa yobude bawo obude bokugxila, amalensi e-telephoto abangela izikhathi zokuchayeka ezimfushane kakhulu. Ngaphandle kwezikhathi zokuchayeka ezinde ukuze kubanjwe ukukhanya okwanele, izinkanyezi zizovela njengemigqa efiphele ngenxa yokujikeleza koMhlaba, okuthinta ikhwalithi yesithombe. Ngakho-ke, uma usebenzisa amalensi e-telephoto ukuthwebula isibhakabhaka sasebusuku, imishini efana nezindawo zokubeka izinkanyezi ngokuvamile iyadingeka ukuze kuncishiswe imiphumela yokuhamba kwezinkanyezi.
(3)Umgodi wokuvula ulinganiselwe kakhulu, okuholela ekungeneni kokukhanya okwanele
Amalensi e-Telephoto ngokuvamile anezimbobo ezincane, kuyilapho i-astrophotography ngokuvamile idinga izimbobo ezinkulu (njenge-f/2.8 noma i-f/1.4) ukuze kwandiswe ukuhlangana kokukhanya futhi kufinyezwe isikhathi sokuvezwa. Ukuvulwa okuncane kwamalensi e-telephoto kuholela esithombeni esimnyama, esidinga ukuzwela okuphezulu kwe-ISO, okwandisa umsindo wesithombe futhi kuthinte ikhwalithi yesithombe.
Imikhawulo yokusebenzisa amalensi e-telephoto ukuze uthwebule isibhakabhaka ebusuku isobala kakhulu.
(4)Ukwakheka nokugxila kuyinselele kakhulu
Ukuthwebula izithombe zezinkanyezi kudinga ukugxila okuqondile kuze kube sekupheleni (∞), kodwa amalensi e-telephoto anensimu encane yokubuka kanye nokujula kwensimu okungajulile kakhulu. Ukugxila ngesandla kanye nokwakheka kungabangela kalula izinkanyezi ezifiphele ngenxa yamaphutha amancane. Lokhu kudinga ukuthembela ekukhulisweni kokubuka bukhoma ukuze kugxilwe ngesandla enkanyezini ekhanyayo, okwenza inqubo ibe nzima kakhulu. Ngokuphambene nalokho,amalensi ane-engeli ebanziinensimu ejulile kakhulu, enikeza ukubekezelela okukhulu kwamaphutha okugxila.
(5)Izidingo zokuqina kwemishini ziphakeme kakhulu
Ngisho noma kufakwe endaweni esenyakatho, ukukhulisa okuphezulu kwelensi ye-telephoto kwandisa imiphumela yokushukuma kwekhamera. I-tripod ezinzile kanye nekhanda le-tripod eliqinile kubalulekile, futhi kungadingeka ukuthi usebenzise i-mirror lock-up kanye ne-remote shutter remote/cable release ukuze unciphise ukudlidliza kwekhamera.
Ngaphezu kwalokho, ukudubula isibhakabhaka sasebusuku ngelensi ye-telephoto kungadinga umsebenzi oyinkimbinkimbi kakhulu wokucubungula ngemuva kokucubungula ukuze kusingathwe izinkinga ezifana nombala wezinkanyezi kanye nokucaca.

2.Ukusetshenziswa kwamalensi e-telephoto ekuthwebuleni isibhakabhaka sasebusuku
Nakubaamalensi e-telephotoazifaneleki ukuthwebula izithombe ezindaweni ezibanzi zesibhakabhaka sasebusuku, ziyasebenza kwezinye izinhlobo ze-astrophotography.
(1)Ukuthwebula izithombe ezinemininingwane yezindawo ezithile zesibhakabhaka sasebusuku
Amalensi e-Telephoto angakhulisa izindawo ezithile zesibhakabhaka sasebusuku, agqamise izinto ezikude esibhakabhakeni esijulile (njenge-nebulae, amaqoqo ezinkanyezi, kanye nemithala) noma izingxenye ze-Milky Way, okwenza zivelele ohlakeni futhi zembule imininingwane emangalisayo kanye nomuzwa wobukhulu.
Isibonelo, zingasetshenziswa ukuthwebula izithombe zemigodi ebusweni benyanga, izinyanga zikaJupiter, noma imininingwane yezinkanyezi ezidumile njenge-Orion, okuholela ezithombeni ezithinta kakhulu.
(2)Ukucindezela ubudlelwano phakathi kwesibhakabhaka esigcwele izinkanyezi kanye nezwe
Ngokusebenzisa umphumela "wokucindezela kwendawo" wamalensi e-telephoto, izindawo ezikude (njengeziqongo zezintaba noma izindlu zokukhanyisa) zingahlanganiswa eduze nesibhakabhaka esigcwele izinkanyezi, kugwenywe inkinga yokuthi indawo ibonakale incane kakhulu ezithombeni ezibanzi, futhi kudalwe ukwakheka okuyingqayizivele (isibonelo, ukwenza iziqongo zezintaba zibonakale "zisekela" ingxenye ye-Milky Way). Lokhu kucindezelwa kwesikhala kwenza izinkanyezi zibonakale ziminyene ohlakeni, kudala umphumela omangalisayo wokubuka.

(3)Ukuthwebula ingxenye yemizila yezinkanyezi
Amalensi e-Telephotozisetshenziswa ekuthwebuleni izithombe zomzila wezinkanyezi ukugxila engxenyeni ethile yezindilinga zomzila wezinkanyezi ezizungeze iPolaris, okuholela ezindilinga eziminyene nezinezingqimba eziningi, kugwenywe ukubonakala "okuncane" kwezithombe zomzila wezinkanyezi ezine-engeli ebanzi.
Ngamafuphi, amalensi e-telephoto awayona inketho engcono kakhulu ye-astrophotography futhi anemikhawulo ebalulekile kulo mkhakha; ngakho-ke, kuyalulekwa ukuthi uqaphele lapho uwakhetha. Nge-astrophotography, amalensi e-telephoto afaneleka kakhulu ekuthwebuleni izinhlobo ezithile zezinto zasezulwini, njengezinto ezijulile zesibhakabhaka kanye nezindawo ezisendaweni zesibhakabhaka sasebusuku.
Imicabango Yokugcina:
Ngokusebenzisana nochwepheshe eChuangAn, kokubili ukuklama kanye nokukhiqiza kuphathwa onjiniyela abanekhono eliphezulu. Njengengxenye yenqubo yokuthenga, ummeleli wenkampani angachaza ngokuningiliziwe ulwazi oluthile mayelana nohlobo lwelensi ofisa ukuyithenga. Uchungechunge lwemikhiqizo yelensi kaChuangAn lusetshenziswa ezinhlobonhlobo zezicelo, kusukela ekuqapheni, ekuskeneni, kuma-drones, ezimotweni kuya emakhaya ahlakaniphile, njll. I-ChuangAn inezinhlobo ezahlukene zamalensi aqediwe, angashintshwa noma enziwe ngezifiso ngokwezidingo zakho. Xhumana nathi ngokushesha okukhulu.
