Abantu abaningi, baphakamisa amehlo abo esibhakabhakeni esigcwele izinkanyezi, bancoma imfihlakalo ememezana yendawo yangaphandle. Ngifuna ukubheka ezandleni ezingapheli zendawo yonke. Bheka i-crater enyangeni. Izindandatho saturn. I-Nebulae Nezinzalamizane eziningi. Ngakho-ke, namuhla ngizokutshela ukuthi ungasenza kanjani isibonakude ekhaya.
Okokuqala, udinga ukunquma ukuthi yini ukwanda okudingekayo. Iqiniso ngukuthi le nani lenani, isikhathi eside ngokwalo isimo se-telescope. Ngokunyuka kokuthinta okungu-50, ubude buzoba imitha eyi-1, futhi ngamamitha ayi-2. Okungukuthi, ubude besibonakudeli buzoba yimpindiselo ngqo.
Ake sithi kuzoba yisibonakude esingu-50. Okulandelayo udinga ukuthenga amalensi amabili kunoma iyiphi i-salon (noma emakethe). Eyodwa ye-eyepiece (+2) - (+ 5) ama-diopters. Okwesibili - nge-lens (+1) diopter (for 100 izibonakude eziningi ezidingekayo (+0.5) diopter).
Ngemuva kwalokho, unikezwe ama-diameters amalensi, kuyadingeka ukwenza ipayipi, noma amapayipi amabili - umuntu kufanele angene kwelinye eliqinile. Ngaphezu kwalokho, ubude besakhiwo esiphumela (ngokwengeziwe) kufanele balingane nobude obugxile belensi. Kuthu, i-1meter (ye-lens (+1) diopter).
Ungawenza kanjani amapayipi? Ukuze wenze lokhu, kuyadingeka ukuveza izingqimba eziningana zephepha egumbini elihambisanayo ye-rayisising, zibaqoqe nge-epoxy resin (kungaba enye i-glue, kungasetshenziswa yi Izinsalela zangemuva ezilele ngaphandle kwebhizinisi ngemuva kokulungiswa. Ungahlola nge-fiberglass, khona-ke kuzoba ukwakheka okubucayi ngokwengeziwe.
Okulandelayo, sishumeke ku-lens ye-tube lens ye-Outer Lens (+1), naku-Inice Electe (+3) diopter. Ungayenza kanjani? I-fantasy yakho yinto esemqoka yokuqinisekisa ukufana okunembile kanye nokuqondanisa kwamalensi. Kumele kufezeke ukuthi ibanga phakathi kwamalensi lapho ipayipi lisendaweni yobude be-lens lens, esimweni sethu kungamamitha ayi-1. Ngokuzayo, ngosizo lokushintsha le pharamitha, sizokwenza ngokwezifiso ubukhali besithombe sethu.
Ukusetshenziswa okulula kwesibonakude, i-tripod iyadingeka ukuze kulungiswe okucacile. Ngokwanda okuqinile kwe-jitter encane kakhulu yepayipi kuholela ekuguguleni kwesithombe.
Uma unawo amalensi, ungathola ubude babo obugxile ngale ndlela elandelayo: gxila ukukhanya kwelanga endaweni eyisicaba kuze kube yilapho kungathola iphuzu elincane. Ibanga phakathi kwelensi futhi ingaphezulu ubude obugxile.
Ngakho-ke, ukuze kufinyelelwe ukwanda kwesibonakudeni izikhathi ezingama-50, i-lens ku (+1) diopter itholakala ebangeni le-1 ku-lens (+3) diopter.
Ukusondeza okuningi okungu-100, sebenzisa ama-lens (+0.5) no (+3) ngokushintsha ibanga phakathi kwabo amamitha ayi-2.
Futhi kule vidiyo - inqubo yokwakha isibonakude esifanayo:
Jabulela ukubuka kwezinkanyezi!
