Uma ufuna ukubuka ngokuningiliziwe izilwane nezitshalo ezisizungezile, kungathakazelisa kakhulu ukuthola i- ukubona indawo. Ngokungafani nalokho esingakucabanga, akudingi ukunakekelwa okuyinkimbinkimbi. Yinto esingafunda ngayo ngenkathi sinesikhathi esihle kakhulu.
Kodwa, Ungayikhetha kanjani engcono kakhulu? Kuya ngomsebenzi esizowunikeza wona, kuzofanele sikhethe kahle esivumelana nezidingo zethu.
Funda ukuthi ungayikhetha kanjani indawo yokubona
Izingxenye ze-telescope
Yonke isibonakude yakhiwe ngezingxenye ezahlukahlukene okungukuthi:
- Unyawo: iqoqo lemilenze emithathu evame ukuba yinsimbi. Ngenxa yabo, isibonakude sihlala sizinzile.
- Khweza: yingxenye yemishini ejoyina i-tripod ne-tube optical. Zingaba ngesandla (ukunyakaza kwenziwa ngesandla), okuhamba ngemoto (ukunyakaza kwenziwa ngamamoto ku-ekseli elilodwa noma amabili) noma ngekhompyutha (ngeGoTo noma i-GPS system). Izinhlobo ezimbili ziyahlukaniswa:
- I-Altazimuthal: yenza ukunyakaza okuqondile nokuqondile.
- I-Dobsonian: zibekwe endaweni yesikhulumi evumela ukunyakaza okuqondile nokuqondile. Azidingi i-tripod.
- Ingalo eyodwa nemfoloko: lezi yizo ezibamba ishubhu elibonakalayo lisuka ohlangothini ngengalo eyodwa noma ezimbili.
- I-Equatorial: enye yezimbazo zayo, leyo ye-Right Ascension noma i-RA, ihlelwe ngokufana ne-axis yokujikeleza koMhlaba.
- I-Altazimuthal: yenza ukunyakaza okuqondile nokuqondile.
- Ishubhu ebonakalayo: yakhiwe ngamalensi noma izibuko kanye nesiphathi samehlo.
- Injini yokusesha: kuyinto encane enwetshiwe efakwe kushubhu esivumela ukuthi siseshe ngokuningiliziwe ngalokho esifuna ukukubona.
Izinhlobo zamashubhu we-optical
Ngokuya nge-tube optical, kunezinhlobo ezintathu futhi:
- Umbukiso: Futhi okuthiwa amaNewtonia, basebenzisa isibuko ukuthwebula ukukhanya. Yiso esisetshenziswa kakhulu kwisayensi yezinkanyezi.
- I-Retro-reflector: sebenzisa inhlanganisela yezibuko nelensi yokulungisa.
- I-Refractor: basebenzisa uhlelo lwamalensi aguqukayo lapho kukhanywa khona ukukhanya. Yiso esisetshenziselwa ukubheka umhlaba.
Kungani ukhetha indawo yokubona ngaphezu kwe-binoculars?
Yebo, nobabili ningajabulela okuningi, kepha kunomehluko obalulekile kathathu phakathi kokunye okulandelayo:
- Optical tube ububanzi: ububanzi besibuko. Ukuphakama kwayo, ukukhanya okungaphezulu kungakubamba. Endabeni yesilinganiso sokubona, kunconywa ukuthi okungenani kube ngu-40mm. Benza ama-binoculars anobubanzi obunjalo, kepha anesisindo esikhulu (ngine-10mm futhi lapho senginemizuzu engama-30 ngiqala ukubona ukukhathala ezihlakaleni zami).
- Ibanga lokugxila: ubude be-tube. Kubuye kulinganiswe mm. Kungaba yi-100mm, 200mm, njll. Uma isikhathi eside, kuzothatha isikhathi eside ukuthi ukukhanya kufinyelele esibukweni. Akudingeki ukuthi ibe yinde kakhulu ukuze ibe ithuluzi elihle. Eqinisweni, into esemqoka okufanele ibhekwe ububanzi beshubhu.
- Iyanda: ukukhuliswa kwesithombe. Endabeni yokuthola izikhala, zingabandakanya nokusondeza izikhala ezikwazi ukuqhubeka nokukhulisa isithombe. Uma sibona, ngokwesibonelo, ukuthi ikhombisa u-30-70x, singazi ukuthi inani elijwayelekile lokukhulisa liyi-30, kepha lingafinyelela kuma-70 ngokuhlehlisa isithombe.
Yini okufanele ubheke ngaphambi kokukhetha eyodwa?
Ngaphandle kwalokhu esesixoxe ngakho kuze kube manje, kuyadingeka futhi ukuthi sibheke i- insimu yombono. Ukukhulisa okukhulu, insimu yokubuka incane. Ngakolunye uhlangothi, isithombe sizobukeka sikhulu futhi sibukhali, kepha singabuka imininingwane embalwa kakhulu.
Kufanele futhi ucabangele ifayela le- angle yokubuka. Ukubuka kufanele kube ntofontofo, ngakho-ke kunconywa ukuthi ukhethe imodeli ephakamisa eyepiece ngo-45º. Ngakho-ke, isibonakude singahlala sizinzile ngokwengeziwe, into edingeka kakhulu ngezinsuku lapho kuvunguza umoya.
Ekugcineni, noma benenani eliphakeme ngokwanele, kufanele kubhekwe (futhi akukaze kushiwo kangcono) ku izingilazi ezengeziwe zokusabalalisa eziphansi noma amalensi e-ED. Lawa malensi avumela ukuba nesithombe sekhwalithi enhle kakhulu, ukuze inkinga ejwayelekile enalezi zibonakude ezinqabayo ixazululwe: i-chromatism.
Yini angasetshenziselwa yona?
Izibonakude ezisuselwa phansi asetshenziselwa ukubona imvelo, ngenxa izinyoni, noma ngisho ne bona ezinye izinto zendawo yonke, njengenyanga noma izinkanyezi (ilanga lingabonakala, kepha ngesihlungi kuphela). Okunye ukusetshenziswa okuba semfashinini kakhulu ukumba, okungukuthi, ukuhlanganisa ikhamera kushubhu le-optical ukuthatha isithombe esihle kakhulu.
Ngabe izinto noma izilwane zingabonakala kude kakhulu?
Isithombe - Alarconweb.com
Yebo, azikho izinkinga. Eqinisweni, zisetshenziselwa lokho. Izibonakude zasemhlabeni zingamathuluzi awusizo kakhulu "wokuya" kude kakhulu ngaphandle kokusuka kusayithi. Esikubonayo kungaba ngamamayela ambalwa omthetho kude.
Imayela lesimiso, noma imayela lamazwe omhlaba njengoba kwaziwa ngezinye izikhathi, iyunithi yobude, noma ingasetshenziswa kabanzi, ngoba isihloko esibhekene naso singasiza kakhulu. Ilingana cishe ne-1480m, okungukuthi, kungafana nokuthatha igxathu elingaba ngama-73cm.
Ngalokhu, singathola umbono wokuthi lokhu esikubonayo kukude kangakanani.
Ukukhethwa kwamabala wokuthola indawo
Uma usenokungabaza ukuthi iyiphi oyothenga, khona-ke sikushiya nokukhetha kwethu:
