A isipho elimangalisayo umntwana hayi kuphela: yerediyo

Ngenxa ukupheliswa kwizikolo Russian ngeenkwenkwezi zimbalwa nencinane bafundi bayazi into malunga neenkwenkwezi. Kodwa hayi yonke into isonjululwe ulwazi, njengoko abantu ongathanda ukuba bajonge iinkwenkwezi, leyo bonke efanayo okutyekisayo romanticism yakhe nanto. Kuphela ngentambo obhityileyo enokuthi nzima kusisondeza ngakumbi kwezi izikhanyiso, i iteleskopu. Bambalwa abantu abakhange waphupha njengomntwana le teleskopu, apho umntu ukubona zonke inkwenkwezi neplanethi. Unalo ithuba ukuzalisekisa eli phupha, ukuba kungabi ngenxa ngokwabo, ngoko abantwana babo: ukuthenga iteleskopu kubo.

Indlela ukukhetha?

Uninitiated kwi nezo ze-optic akukho lula ukuqonda isakhiwo noba zizibonakude ezilula, singasathethi isixhobo ezintsonkothileyo njenge iteleskopu. Kodwa ke ngongoma kukuba ethile akukho kakhulu ukwazi xa kokuba ikhethwe. Nayiphi samaza uneempawu ezininzi esisiseko eyile: ubukhulu lens, le sikrini kunye sangqa umfundi yokuphuma.

Imiyalelo kuyo nayiphi na imodeli yakho ekhethiweyo, unako ukufumana PostScript, umzekelo, 10x30, apho i-10 a ukukhulisa, 30 - ubukhulu be lens. Le ubuninzi ixhomekeke ubukhulu becala kuluhlu kunye nomgangatho kwakhona, kodwa uleqa indices ezinkulu kakhulu akusiyiyo kuyimfuneko, ngokuba phezulu ubuninzi, inowuthi uzinzo mfanekiso. Ngenxa yoko, ubuninzi enkulu kakhulu lweteleskopu yakho yenza nje umfanekiso.

Ukuze ukuvala esi isiphoso, sebenzisa i ubudeki lens enkulu. Ngako oko, kungona oko kukuthi, ukukhanya kokukhona ufumana, yaye libukhali ukubonakala izinto ezikude. Zama ukukhetha ezo ngawona apho ubukhulu lens ayikho ngaphantsi kweentsuku ezintathu ukuya kwezine amaxesha ngaphezu ratio. Kwi oku kuxhomekeke elandelayo isibonisi esemgangathweni.

Ubukhulu be umfundi yokuphuma iboniswe ndawo, kodwa ubungakanani bayo bangonakala kuqingqwa ngokwahlula-30 ngo-10 (inani lesibini ukuya kuqala). Ngenxa yoko i-3 mm, kwaye sisalathisi umfundi yokuphuma. Elilelona ubukhulu bayo kube ngaphezu kwe-4.25 yaye kungabi ngaphantsi kwe 3,50 mm, kungenjalo iteleskopu yakho ukudala umfanekiso umgangatho izinto waphawula.

Ethandwa kakhulu phakathi zombini iingcali kunye amateurs basebenzisa yerediyo Yukon. Le nkampani ixhasa ukulinganisela phakathi ixabiso kunye nomgangatho, enika elona xabiso eyona ndlela abo okanye ezinye iindlela. Kakade ke, zikho nezinye iinkampani ezininzi, kodwa kutheni esichengeni umgangatho okanye overpay igama enkulu?

Musa ukuqhathwa! Akukho iiteleskopu ukuba bagcine isibhakabhaka ebusuku: ukukhanya encinane kakhulu ukwenzela ukuba umfanekiso yayintle kancinci. Kunjalo Iivenkile nabathengisi badla zama ukudlala kwi Ukungabinalwazi abathengi ngokubalula umsebenzi ngokucacileyo engekhoyo. Soloko ukufunda iimpawu zobugcisa isixhobo ngobunono kwaye musa overpay ukuba iinkcukacha engeyomfuneko.

Ke kaloku, ukuze wazi ukuba ukhethe indlela elungileyo iteleskopu, ngoku lixesha lokuba enze. Yaye khumbula ukuba kweteleskopu - oku nje isixhobo, oko ngoncedo apho wena khumbula ebuntwaneni, ezalisekisa iphupha labo alithandayo. Ukongeza, unika abantwana bakho ithuba, ekhangele esibhakabhakeni, nje ukuba ephupheni alinakuzuzwa, leyo inkulu emangalisayo!
