Abantu abaninzi, baphakamisa amehlo abo kwisibhakabhaka esinenkqantosi, bancoma imfihlakalo yeyokuhambahamba yendawo yangaphandle. Ndifuna ukujonga kwizinto ezingapheliyo zendalo yonke. Jonga iCrater kwiNyanga. Amakhonkco e-saturn. Uninzi lwe-nebulae kunye neenkwenkwezi. Ke ngoko, namhlanje ndiza kukuxelela indlela yokwenza iteleskopu ekhaya.
Okokuqala, kuya kufuneka uthathe isigqibo malunga nokwanda okufunekayo. Inyani yile yokuba ngakumbi elixabiso, ixesha elide iteleskopu ngokwalo. Ngonyuso olungena-thendla, ubude buza kuba yimitha enye, kunye neemitha ezi-2 ezininzi. Oko kukuthi, ubude beteleskopu buza kuphinda kuphinde.
Masithi iya kuba yi-50-teleskopu. Okulandelayo kufuneka uthenge iilensi ezimbini kulo naliphi na isalo (okanye kwimarike). Inye ye-eyeece (+2) - (+ 5) diokster. Okwesibini - kwi-lens (+1) i-diopter (ye-100 yeeteleko ezininzi ezili-100 (+0.5) diokter).
Emva koko, inikwe ii-seameter yeelensi, kufuneka zenze umbhobho, okanye iipayipi ezimbini-umntu kufuneka angene kwelinye gwenxa. Ngapha koko, ubude besakhiwo esiphumelelweyo (ngokomfanekiso) kufuneka silingane nobude obujolise kwilensi. Kwimeko yethu, i-1meter (yelensi (+1) i-diopter).
Wenza njani imibhobho? Ukwenza oku, kuyimfuneko kwimithombo yomoya kwi-rim ye-rim ye-diameti ehambelanayo, ukubamba i-epoxy reshon (inokuba nelinye iglue, kodwa inokusetyenziswa ngu Intsalela yeWallpaper ezilele ngaphandle kweshishini emva kokulungiswa. Ungazama i-fiberglass, ke iya kuba luyilo olunzulu ngakumbi.
Emva koko, sibambelele kwi-lens ye-tube yangaphandle (+1) i-diopter, nakwi-EyepieCe (+3) diokter. Ungayenza njani? I-fantasy yakho yeyona nto iphambili ekuqinisekiseni ngokuhambelana ngokuchanekileyo kunye nolungelelwaniso lweelensi. Kuya kufuneka ifezekiswe ukuba umgama phakathi kweelensi xa umbhobho wawungaphakathi kwelensi yelensi yelensi, kwimeko yethu yimitha enye. Kwixesha elizayo, ngoncedo lokutshintsha le paraerter, siya kwenza browsible umfanekiso wethu.
Ukusetyenziswa ngokulula kweteleskopu, i-tripod ifunekile ukulungiswa okucacileyo. Ngonyuso olunamandla kwi-jitter encinci yombhobho kukhokelela ekukhuthazeni umfanekiso.
Ukuba unayo nayiphi na i-lenses, ungakufumana ubude babo ngeendlela eziphambili: Gxila ukukhanya kwelanga kwindawo ethe tyaba kude kube yindawo encinci. Umgama phakathi kwelensi kunye nomphezulu ubude bokugxila.
Ke, ukuze kufezekiswe ukwanda kweteleskopu malunga namaxesha angama-50, ilensi kwi (+1) i-diapter ibekwe kumgama omnye kwiilensi (+3) diokter.
Ukufumana i-ZOOR ye-100 ye-ZOOD, sebenzisa iilensi (+0.5) kunye (+3) ngokutshintsha umgama phakathi kwazo ezi-2 zeemitha.
Kwaye kule vidiyo-inkqubo yokwenza iteleskopu efanayo:
Yonwabela umbono we-ostromiomine!
