Muaj qee yam uas ua rau muaj kev ntxhov siab ntau dua li siv hmo yav tsaus ntuj thaij duab saum ntuj nrog koj lub tsom iav, tsuas yog txhawm rau pom tias txhua yam ntawm koj cov duab yog me ntsis ntawm kev tsom …
Focussing lub tsom iav raj rau astrophotography yog qhov nyuaj heev, qhov sib txawv ntawm cov hnub qub txhais tau tias lawv yeej tsis tsom mus rau ib qho; nws nyuaj hais thaum lawv tsawg tshaj plaws, thiab nyuaj rau taug qab seb txoj kev tsom mus rau qhov xav tau kho li cas.
Hmoov zoo Pavel Bahtinov tau tsim qhov kev daws teeb meem zoo rov qab rau xyoo 2005. Txoj hauv kev zoo tshaj plaws kom ua tiav qhov pom tseeb yog siv daim npog ntsej muag sib txawv (daim npog ntsej muag Bahtinov) kom pom kev zoo ntawm ob qho tib si tsom mus rau lub tsom iav zoo li cas thiab cov lus qhia uas nws tawm ntawm kev tsom xam
Koj tuaj yeem yuav cov no lossis ua rau koj tus kheej (Kuv yuav sau cov lus qhia ntawm laser txiav ib qho sai li sai tau thaum kuv mus ncig rau lasers ib tus kheej!) yooj yim thiab yuav luag dawb … siv cov kab xev hluav taws xob nkaus xwb.
Rau kev zam kev tsis ntseeg, thaum tsom tsom tsom iav, daim kab xev raug tshem tawm kom muab cov duab ntse.
Rau qhov no koj yuav xav tau:
Ib co kab xev hluav taws xob. Ib daim kab xev tsis zoo uas tsis tawm qhov nplaum tom qab yuav ua haujlwm, tab sis PVC daim kab xev hluav taws xob yog qhov kuv siv.
Reflector tsom iav raj. Kuv siv 8 nti Schmidt Cassegrain (Nexstar 8SE), tab sis nws yuav tsum ua haujlwm zoo ib yam nrog Newtonians lossis Maks feem ntau. Koj yuav tuaj yeem ua qhov no nrog tus refractor tab sis nws tsis yooj yim dua thiab txaus ntshai kom tau daim kab xev ntawm lub lens.
Lub koob yees duab nrog lub adapter haum. Tsis nruj me ntsis tsim nyog, raws li koj tuaj yeem tsom mus rau kev saib ncaj qha nrog cov txheej txheem no. Kuv siv Sony Alpha a6000 ntawm 1.25 qhov muag qhov muag txuas.
Nco tseg: Telescopes tsis yooj yim, yog li tsis txhob muab lub zog loj rau yam lossis koj yuav de-collimate (lossis phem dua) koj lub tsom iav!
Txhua daim duab yog los ntawm kuv lub tsom iav, tsom mus rau siv txoj hauv kev no, thiab tsis yog photoshopped dhau qhov ci ci/kev hloov pauv sib txawv (tsis txawm tias teeb duab sib dhos)
Kauj Ruam 1: Ua tib zoo ntxiv cov kab xev los ua daim ntawv 'Y'
Tua ib daim kab xev ntev me ntsis tshaj qhov ncig ntawm koj lub tsom iav raj. Maj mam lo ib qho kawg ntawm qhov no mus rau qhov nruab nrab kev txhawb nqa nrog daim kab xev tuav nruj kab rov tav tawm los rau ntawm ntug ntawm txoj haujlwm 9 teev. Txhua lub sijhawm kom ntseeg tau tias daim kab xev nyob deb ntawm lub iav phaj kho kom tsis txhob muaj qhov seem ntawm lub lens. Kaw qhov kawg kom zoo zoo rau ntawm ntug nrog daim kab xev kaw kom txaus txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau, thaum ua tib zoo saib kom tsis txhob rub nruj txaus kom tsis thim daim kab xev lossis cuam tshuam txog kev sib tw ntawm qhov thib ob.
Ib yam nkaus, ua tib zoo ntxiv ob daim kab xev rau lwm sab, kaum ib ncig 20 ° ib sab ntawm kab rov tav (piv txwv li qis dua 2 teev thiab siab dua 4 teev). Saib cov duab kom paub meej.
Yog tias tau sim ntawm tus kws kho qhov muag, qhov Y yuav xav tau ntxiv hauv ib qho!
Kauj Ruam 2: Ntxiv cov kab ntxiv los tsim cov kab nqaim
Tam sim no ntxiv 4 kab ntawv ntxiv, ob sab, sib dhos nrog cov kab ntawv yav dhau los.
Lub hom phiaj ntawm no yog txhawm rau tsim ob txoj kab tav toj kwv yees li 5m dav rau ib sab, thiab ob lub kaum qhov qhib (dua 5mm dav) rau lwm sab. Nws yog ib qho tseem ceeb kom tau txais daim kab xev raws li ua tau raws li qhov uas lub qhov yog qhov dav tas mus li txhua txoj kev. Qhov dav dav ntawm lub qhov yog qhov tseem ceeb dua. Ib zaug ntxiv saib daim duab kom paub meej.
Yog tias tau sim ntawm tus refractor qhov ntev me me ntawm daim kab xev yuav xav tau kom khi txhua daim kab xev ua ke nyob hauv nruab nrab yog li nws tau tuav nruj. Kuv tsis tau sim qhov no, thiab cia siab tias qhov no yuav nyuaj tab sis tsis yooj yim sua!
Kauj Ruam 3: Taw qhia lub tsom iav raj ntawm Lub Hnub Qub Zoo thiab Ua Tsaug Ntau

Yog tias koj muaj lub ntsej muag-pab txhawb lub ntsej muag saib, siv nws tam sim no txhawm rau ua kom yooj yim pom.
Qhov spikes yog tshwm sim los ntawm qhov nqaim qhov sib txawv ntawm lub hnub qub lub teeb. Sab nrog cov kab rov tav ua rau ntsug 'Kuv' spike, thaum ob lub kaum qhov qhib ua ob lub kaum sab xis ua ib qho 'X'. Raws li qhov ua kom pom tseeb tau hloov pauv ze qhov ua kom pom tseeb, I thiab X swb ib sab txheeb ze ib leeg.
Kho qhov ua kom pom tseeb kom txog thaum lawv sib tshooj, sau tseg txoj kev uas kuv txav mus thaum tus tsom mus rau tig lub moos.
Kauj Ruam 4: Ua Kom Kho Kom Zoo Dua Rau Hauv I Hauv X

Koj yuav pom tias qhov kev hloov pauv tau ua tiav zoo dua li qhov koj yuav tau ua kom pom tseeb ntawm qhov muag raws li txoj kev no tau txais kev tsom mus kom raug.
