Telescope: indlela ukukhetha ngendlela efanele

Abantu ababeka ziyazithanda ukufunda izinkanyezi, babhekana isidingo sokuthenga isibonakude. Indlela ukukhetha isibonakude? Lo mbuzo impela eziyinkimbinkimbi. Kodwa kufanele sikhumbule into eyodwa elula - awusoze uthole kudivayisi esebenzisa okungase kwenziwe ngokuphelele zonke izinhlobo kokuma. Yingakho kubalulekile ukunquma ekuqaleni lokho uthola isibonakude.

Kanjani ukuze uyikhethe ngesisekelo izinhlobo ezikhona? Inketho kuqala - a refractor. Le divayisi optical lokuqoqa ukukhanya esebenzisa uhlelo lens. zako yilezi: ikwazi kudonse yisikhathi ngokwanele eside, inenani elikhulu emkhakheni buka, edzimelele ezinzile, ukulahlekelwa ukukhanya kulokhu ephansi, njengoba evele yesibili phakathi eyepiece kanye lens bengekho. Ikhwalithi yesithombe esikhaleni thuluzi uphakeme, sikwazi ukukhuluma ukuvikelwa ezinhle ngothuli. Kodwa uma unentshisekelo kanjani ukukhetha isibonakude Wabasaqalayo, kubalulekile ukusho ukushiyeka refractors. Lokhu impambuko ye-chromatic, ukuthi, kungenzeka isithombe ukucaciseleka encishisiwe, kanye ukubukeka umbala wabuka, izindawo, imivimbo. beso Isihlobo kulokhu incane, okusho ukuthi beso ratio encane. Futhi kusimo main - usayizi esezingeni elifanele.

Nge reflectors kuhlukile. Lolu hlobo lwesibili ngezibonakude. Izinzuzo: ngentengo ephansi, usayizi compact, futhi kungakho ukuhamba, a beso enkulu chromatique egcwele. Kodwa kukhona nemibi lowo isibonakude. Kanjani ukukhetha, futhi kungakhathaliseki ukuthi, uma luyanda ukuzwela lokulingisa ukusonteka, ngenhlanhla, zisheshe futhi ukusetshenziswa mnyama, kungani konakalisa isithombe? Lapho ethwele idivayisi ezinjalo kulula lokudlela up. Futhi okwashiwo eliwumhlaba izinto isithombe uzobe nabokhulumile.

Uma sikhuluma kwenkululeko isicelo, refractors esetshenziswa kakhulu lapho ebona amaplanethi, iNyanga, izinto phansi futhi reflectors - isikhala izinto ezijulile, okungukuthi, amaqoqo, mafu, imithala. Ngakho nquma ukuthi ukukhetha isibonakude ezinhle, esekelwe imigomo.

Olunye uhlobo amathuluzi okubona Imininingwane - esibukweni lens. Futhi zingafani izimfanelo zabo. Okokuqala, it is a icwecwe, achromatic, isithombe muhle ngaphezu kobubanzi buka, futhi bavikelekile uthuli ngokwanele, ngoba uphawu lwabo tube. I yokuntula zihlanganisa amanani aphezulu isisindo eziningi ehloniphekile, eside ukukhanya ukulahlekelwa.

Une ukuthenga isibonakude. Kanjani ukukhetha, futhi yazise izici eziningi. Ngokwesibonelo, ubude ebalulekile, lens ubukhulu, amazwi kaPawulu angena ajule amandla, isinqumo nokunye.

Ngaphambi kokuthi uthenge, zibuze imibuzo eminingana: Yini ngempela yini ozoyenza ukuze ubuke, lapho, yimalini babe? Okuningi efanelekayo Wabasaqalayo refractor, ngoba ukufunda kungenzeka amaplanethi nenyanga. Khumbula, e iliphi igumbi endlini yakho kwesibonakude. Uma kuvulandi encane, kubalulekile ukukhetha kugqame. Futhi endabeni nge ivulekile Loggia okwaziyo futhi refractor. Amanani amadivayisi optical enjalo isukela $ 15 futhi kakhulu ngendlela ayizinkulungwane eziyishumi. Ethandwa kakhulu CELESTRON izibonakude, STURMAN, KONUS, nokunye.
