Uyikhetha njani indawo yokubala?

Xa ufuna ukubona ngokweenkcukacha izilwanyana kunye neentyatyambo ezisijikelezileyo, kunokuba ngumdla kakhulu ukufumana indawo yokubona. Ngokungafaniyo nento esinokuyicinga, ayifuni ulondolozo olunzima. Yinto esinokufunda ngayo ngelixa sonwabile.

Kodwa, Ungayikhetha njani eyona ilungileyo? Kuxhomekeke kuluncedo esiza kulinika lona, ​​kuya kufuneka sikhethe kakuhle elungele iimfuno zethu.

Funda indlela yokukhetha indawo yokubona

Amalungu eTeleskopu

Yonke iteleskopu yenziwe ngamacandelo ahlukeneyo:

• Uhambo lwesithathu: yiseti yemilenze emithathu edla ngokuba sisinyithi. Enkosi kubo, iteleskopu ihlala izinzile.
• Nyuka: yinxalenye yoomatshini ejoyina i-tripod kunye netyhubhu ebonakalayo. Zingabhalwa ngesandla (iintshukumo zenziwa ngesandla), zihamba ngemoto (iintshukumo zenziwa ngeemoto kwi-axes enye okanye ezimbini) okanye ikhompyuter (ngeGoTo okanye inkqubo ye-GPS). Zimbini iintlobo ezahlukileyo:
  • I-Altazimuthal: yenza ukunyakaza okuthe tye kunye nkqo.
    • I-Dobsonian: zibekwe eqongeni ezivumela ukunyakaza okuthe tye kunye nkqo. Ayifuni i-tripod.
    • Ingalo enye kunye nefoloko: ezi zezi zibambe ityhubhu ebonakalayo kwicala elinye okanye iingalo ezimbini.
  • I-Equatorial: enye yee-axes zayo, leyo ye-Right Ascension okanye i-RA, icwangciswe ngokuhambelana ne-axis yokujikeleza koMhlaba.
• Ityhubhu yokubonisa: yenziwe ngeelensi okanye izibuko kunye nesiphathi samehlo.
• Injini yokukhangela: yinto encinci edityanisiweyo ebekwe kumbhobho esivumela ukuba sikhangele ngokweenkcukacha zento esifuna ukuyibona.

Iindidi zeetyhubhu ezibonakalayo

Kuxhomekeke kumbhobho we-optical, kukho iintlobo ezintathu:

• UkucingisisaIkwabizwa ngokuba ngabantu baseNewtonia, basebenzisa isipili ukubamba ukukhanya. Yeyona isetyenziswa kakhulu kwi-astronomy.
• Ukubonakalisa kwakhona: Sebenzisa indibaniselwano yezibuko kunye nelensi yokulungisa.
• Iphinda ibonakalise: Basebenzisa inkqubo yelensi eguqukayo apho ukukhanya kuphindwe kwakhishwa khona. Yeyona isetyenziselwa ukubonwa komhlaba.

Kutheni ukhetha indawo yokubona ngaphezulu kwee-binoculars?

Ewe, ngazo zombini unako ukonwabela okuninzi, kodwa kukho umahluko kathathu obalulekileyo phakathi kwenye kunye nokunye oku:

• Ububanzi beetyhubhu ezibonakalayo: bububanzi besipili. Ukuphakama kwayo, ukukhanya ngakumbi kunokubamba. Kwimeko yokujonga indawo, kuyacetyiswa ukuba ubuncinci ibe yi-40mm. Benza i-binoculars enobubanzi, kodwa banobunzima kakhulu (ndinayo malunga ne-10mm kwaye xa bendijikeleze imizuzu engama-30 sele ndiqalisile ukuqaphela ukudinwa ezihlahleni zam).
• Umgama ekugxilwe kuwo: ngaba ubude ityhubhu. Ikulinganiswa nge-mm. Inokuba yi-100mm, 200mm, njl. Ixesha elide, kokukhona kuya kuthatha ukukhanya ukuze kufikelele esipilini. Akunyanzelekanga ukuba ibe lixesha elide ukuze ibe sisixhobo esihle. Ngapha koko, eyona nto iphambili ekufuneka uyijongile bububanzi betyhubhu.
• Iyanda: kukukhulisa umfanekiso. Kwimeko yokubona ubungakanani, banokubandakanya ukusondeza iijwayi ezinokukhulisa umfanekiso. Ukuba sibona, umzekelo, ukuba ibonisa u-30-70x, sinokwazi ukuba ixabiso eliqhelekileyo lokukhulisa lingama-30, kodwa lingafikelela kuma-70 ngokusondeza.

Yintoni ekufuneka ujonge kuyo ngaphambi kokukhetha enye?

Ngaphandle kwento esele sithethe ngayo ukuza kuthi ga ngoku, kubalulekile ukuba siqwalasele icandelo lombono. Inkulu ukukhulisa, incinci ibala lokujonga. Kwelinye icala, umfanekiso uya kubonakala umkhulu kwaye ubukhali, kodwa sinokujonga kuphela kwiinkcukacha ezimbalwa.

Kuya kufuneka uthathele ingqalelo i imbonakalo yokujonga. Ukuqwalaselwa kufuneka kukhululeke, ke kuyacetyiswa ukuba ukhethe imodeli ephakamisa iliso nge-45º. Ke, iteleskopu inokuhlala izinzile ngakumbi, into eyimfuneko kakhulu kwiintsuku xa kuvuthuza umoya.

Okokugqibela, kwaye nangona benamaxabiso aphezulu ngokufanelekileyo, kufanelekile ukuba ujonge (kwaye ungaze uthethe ngcono) e iiglasi ezasasazwayo ezingaphezulu okanye iilensi ze-ED. Ezi lensi zivumela ukuba zibe nomfanekiso womgangatho olunge kakhulu, ukuze ingxaki eqhelekileyo ukuba iiteleskopu ezinqabileyo zisonjululwe: i-chromatism.

Zingasetyenziselwa ntoni?

Iiteleskopu ezisemhlabeni zisetyenziselwa ukubona indalo, ngenxa iintaka ezinendawo, okanye nokuba bona ezinye zezinto ezikhoyo, njengenyanga okanye iinkwenkwezi (ilanga linokubonakala, kodwa ngesihluzi kuphela). Olunye usetyenziso oluya lubalasela kakhulu ukumbaOko kukuthi, ukudibanisa ikhamera kwityhubhu ye-optical ukuthatha ifoto esemgangathweni.

Ngaba izinto okanye izilwanyana zingabonwa zikude kakhulu?

Ewe, akukho ngxaki. Ngapha koko, zisetyenziselwa ngokuchanekileyo loo nto. Iiteleskopu zasemhlabeni zizixhobo eziluncedo kakhulu "zokuhamba" kude kakhulu ngaphandle kokuhamba kwisiza. Into esinokuyibona inokuba yimithetho emininzi yeemayile kude.

Imayile yemithetho, okanye imayile yamazwe aphesheya njengoko isaziwa ngamanye amaxesha, iyunithi yobude ethi, nangona ingasetyenziswa ngokubanzi, kumxholo esijongana nawo unokuba luncedo kakhulu. Ilingana malunga ne-1480mOko kukuthi, kuya kufana nokuthatha inyathelo malunga ne-73cm.

Ngale nto, sinokufumana umbono wokuba ikude kangakanani le nto siyibonayo.
