Te whakamāramatanga o tētahi karu tiro whetū (ngā karu tirotiro)
Ko te karu tiro whetū, te karu tiro whetū rānei, he taputapu whatu e whakamahia ana hei āwhina i te kanohi kia kite mārama i ngā mea o te rangi pērā i ngā whetū, ngā aorangi, ngā amiorangi, me ētahi atu. Ahakoa he tino rahi te rahi o ngā mea o te rangi, he tino tawhiti te tawhiti i waenga i ngā mea o te rangi, ā, ina tirohia ki te kanohi, ka āhua iti ngā mea o te rangi. Ko te mahi a te karu tiro whetū he whakanui i te ahua o ngā mea o te rangi kia mārama ai te kite ki te kanohi.
Ngā Momo Karu Whānui
He maha ngā momo karu tiro whetū, tae atu ki ngā karu tiro whakaata me ngā karu tiro whakaata. Ko te karu tiro whakaata, e mōhiotia ana ko te karu tiro Keplerian, he mea tito mai i ngā karu tiro pūkohu e rua e whakanohoia ana ki ngā pito e rua o te ngongo. Ko te karu tiro pūkohu e tawhiti atu ana i te kanohi o te kaimātakitaki ka kiia ko te karu tiro whāinga, ko te karu tiro pūkohu e tata atu ana ki te kanohi ka kiia ko te karu tiro kanohi. Hei whakaputa i tētahi whakaahua mārama o tētahi mea rangi, me nui te horahanga o te mata o te karu tiro whāinga. He uaua te hanga karu tiro whānui, nō reira kāore i te tino nui ngā karu tiro whakaata. Ko ngā karu tiro tino nui he karu tiro whakaata. Ka whakamahia e ngā karu tiro whakaata he whakaata piko hei whakaata whāinga.
Ka arotahi tēnei tuhinga ki te matapakinga o ngā karu tiro whetū hurihuri, ngā karu tiro Keplerian rānei.
Te Mahi a te Karu Whānui Whakaata
E rua ngā karāhe pūkohu o te karu tiro whetū hurihuri. Ko te karāhe pūkohu e tawhiti atu ana i te kanohi o te kaimātakitaki ka kiia ko te karāhe whāinga, ko te karāhe pūkohu e tata atu ana ki te kanohi o te kaimātakitaki ka kiia ko te karāhe karu, ko te karāhe karu rānei. Nā te tawhiti o tētahi mea ka iti rawa te koki i waenganui i te mea me te karāhe whāinga. Nō reira, ko te mahi a te karāhe whāinga he whakatata ake i te ahua ki te karāhe karu kia nui ake ai te koki. Ko te mahi a te karāhe karu he whakanui ake i te koki kia nui ake ai te ahua i hangaia ki te retina.
He tino tawhiti te tawhiti i waenganui i te mea me te karāhe arotahi, ā, e kiia ana he mutunga kore. E ai ki te tuhinga mō te karāhe arotahi, ki te tino tawhiti, ki te mutunga kore rānei te mea, kei te pūwāhi arotahi tonu te ahua o te karāhe arotahi. He tūturu, he huripokitia, he whakaititia te ahua. Nā te mea kei te pūwāhi arotahi o te karāhe arotahi te ahua, ko te tawhiti i waenganui i te ahua me te karāhe arotahi (s ob ') he rite ki te roa arotahi o te karāhe arotahi (f ob ).
He tūturu te ahua i hangaia e te karu arotahi, nō reira ka kitea he mea e te karu tirohanga hei mea. Mēnā he iti rawa te wāhi e taunga ai te kanohi, ka tawhiti rawa te ahua i hangaia e te karu tirohanga. E ai ki te whakamārama i roto i te kaupapa. whakaahua karaihe kōpiko, kia kore ai e mutu te tawhiti o te ahua i hangaia e te karu tirohanga, ko te ahua tūturu i hangaia e te karu tirohanga whāinga, ā, e kiia ana he mea e te karu tirohanga whāinga, me noho hoki ki te karu tirohanga whāinga o te karu tirohanga whāinga. Nō reira, ka taea te whakatau ko te karu tirohanga whāinga o ngā karu tirohanga whāinga e rua me te karu tirohanga whāinga tuatahi o te karu tirohanga whāinga ka ōrite, e whakaaturia ana i te pikitia. Ina rite te roa o te arotahi o te karu tirohanga whāinga (fok) he rite ki te tawhiti o te ahua tūturu mai i te karu arotahi (sok) kātahi ka mariko, ka hurihia, ka whakanuia, ā, ka tawhiti mutunga kore te ahua whakamutunga i hangaia e te karu tirohanga. Kāore te tawhiti mutunga kore o te ahua e tohu ana he mutunga kore te rahi o te ahua.
I runga i te ahua me te whakamārama i runga ake nei, ka taea te whakatau ko te tawhiti i waenga i te karāhe arotahi me te karāhe karu o te karu tirohanga māmā = te roa o te karu tirohanga māmā = te roa arotahi o te karāhe arotahi (f ob ) + te roa arotahi o te karāhe karu tirohanga (f ok ).
Ki te taea te urutau pai rawa atu o te kanohi, ko te ahua i hangaia e te karu tirohanga kanohi kei te pūwāhi e tata ana ki te kanohi noa, kei te 25 cm rānei i mua i te karu tirohanga kanohi, kei reira te tawhiti o te ahua (s ok ') he iti iho i te roa arotahi o te karu tirohanga kanohi (f ok ). Ko te tawhiti o te ahua i hangaia e te karu tirohanga kanohi (s ok ') he iti iho i te roa arotahi o te karu tirohanga kanohi (f ok ) kia mariko ai, kia hurihia ai te ahua. Ka taea te ako i tētahi whakamārama whānui ake i roto i te kaupapa o ngā tātai karu tirohanga whetu (karu tirohanga rua).
Te Whakanui Katoa o ngā Karu Whānui
He nui ake te rahi o te ahua o tētahi mea e kitea ana mā te karu tirohanga whetū ina tirohia e te kanohi he iti rawa te wāhi e noho ai, e te kanohi rānei he nui rawa te wāhi e noho ai? Ko tēhea te mea pai hei whakamahi hei karu tirohanga me te karu tirohanga, he karu tirohanga pūkohu he nui te roa o te arotahi, he karu tirohanga pūkohu rānei he iti te roa o te arotahi? Ka taea te whakautu i ēnei pātai i muri i tō ako i te tātai mō tētahi karu tirohanga whetū (ngā karu tirotiro).
