Mitemo yekushandisa:

1. Dhonza nepakati tsoka dzinotsigira, isa telescope barrel pajoko uye uigadzirise nemakona makuru ekukiya.

2. Isai zenith girazi muhumburumbira inotarisisa uye gadzirisa nemakona anowirirana.

3. Isa ziso pagirazi re zenith uye uigadzirise nemakona anowirirana.

4. Kana iwe uchida kukudza negirazi rakanaka, riise pakati peziso uye lens barrel (hapana chikonzero chekuisa 90 degree zenith mirror), kuitira kuti iwe uone muviri wekudenga.

Chii chinonzi Astronomical telescope?

Teresikopu yenyeredzi ndicho chishandiso chikuru chekutarisa mitumbi yedenga uye kutora ruzivo rwekudenga.Kubva Galileo akaita teresikopu yokutanga muna 1609, teresikopu yave ichingoenderera mberi.Kubva pane optical band kusvika kubhendi rakazara, kubva pasi kuenda muchadenga, kugona kwekutarisa kweteresikopu kuri kuramba kwakasimba uye kwakasimba, uye ruzivo rwemuviri wekudenga runogona kutorwa.Vanhu vane telescopes mu electromagnetic wave band, neutrinos, gravitational waves, cosmic rays zvichingodaro.

Nhoroondo Yebudiriro:

Telescope yakabva kumagirazi.Vanhu vakatanga kushandisa magirazi makore 700 apfuura.Around 1300 ad, maItaly akatanga kugadzira magirazi ekuverenga ane convex lenzi.Around 1450 ad, myopia magirazi akaonekawo.Muna 1608, mumwe mudzidzi weH. Lippershey, mugadziri wezvipfeko zvemaziso wechiDutch, akawana netsaona kuti nokurongedza malenzi maviri pamwe chete, ainyatsoona zvinhu zviri kure.Muna 1609, apo Galileo, musayendisiti wokuItaly, akanzwa nezvechigadzirwa chacho, akabva agadzira teresikopu yake amene ndokuishandisa kuona nyeredzi.Kubva ipapo, telescope yekutanga yenyeredzi yakazvarwa.Galileo akacherekedza zviitiko zvemasunspots, mwedzi, masatellite eJupiter (Galileo satellites) uye purofiti nekurasikirwa kweVenus neteresikopu yake, iyo yakatsigira zvakasimba dzidziso yaCopernicus yeheliocentric.Teresikopu yaGalileo yakagadzirwa nenheyo yekudzokorodza kwechiedza, saka inonzi refractor.

Muna 1663, muongorori wemuchadenga wekuScotland, Gregory, akagadzira girazi reGregory achishandisa chirevo chekuratidza chiedza, asi rakanga risingafarirwe nekuda kwehunyanzvi hwekugadzira zvinhu.Muna 1667, musayendisiti wokuBritain anonzi Newton akavandudza pfungwa yaGregory zvishoma ndokugadzira girazi reNewtonian.Aperture yaro ingori 2.5cm, asi magnification inodarika ka30.Inobvisawo mutsauko weruvara weteresikopu yekudzokesa, izvo zvinoita kuti zviite zvakanyanya.Muna 1672, muFrench Cassegrain akagadzira inonyanya kushandiswa Cassegrain reflector nekushandisa concave uye convex magirazi.Teresikopu ine hurefu hwakareba hwekutarisa, muviri mupfupi lenzi, kukudza kukuru uye mufananidzo wakajeka;Inogona kushandiswa kutora mifananidzo yakakura uye diki mitumbi yedenga mumunda.Teresikopu yeHubble inoshandisa rudzi urwu rweteresikopu inotarisisa.

Muna 1781, vazivi venyeredzi vekuBritain, W. Herschel naC. Herschel vakawana Uranus ine girazi rekuvhura rakazvigadzira remasendimita gumi nemashanu.Kubva ipapo, vazivi venyeredzi vakawedzera mabasa mazhinji kune teresikopu kuti ive nekwaniso yekuongorora kwekuona uye zvichingodaro.Muna 1862, nyanzvi dzenyeredzi dzeAmerica Clark nemwanakomana wake (A. Clark naA. g. Clark) vakagadzira 47 cm aperture refractor uye vakatora mifananidzo yeSirius shamwari nyeredzi.Muna 1908, muongorori wemuchadenga wekuAmerica Haier akatungamira kuvakwa kwegirazi rekuvhura 1.53 metre kuti ritore nyeredzi dzeSirius shamwari.Muna 1948, teresikopu yeHaier yakapedzwa.Kuvhura kwayo kwemamita mashanu.

Muna 1931, chiremba wemaziso wekuGermany Schmidt akagadzira teresikopu yeSchmidt, uye muna 1941, muongorori wenyeredzi weSoviet Mark sutov akaita chiratidzo chesutov Cassegrain reentry mirror, icho chakapfumisa marudzi eteresikopu.

Munguva dzazvino uno nedzazvino uno, materesikopu enyeredzi haasati achaganhurirwa kumabhendi emaziso.Muna 1932, American Radio Engineers vakaona mwaranzi yeredhiyo kubva pakati peMilky Way galaxy, zvichiratidza kuzvarwa kweredhiyo nyeredzi.Mushure mekutangwa kwemasetellita akagadzirwa nevanhu muna 1957, materesikopu emuchadenga akabudirira.Kubva muzana ramakore idzva, materesikopu matsva akadai seneutrinos, zvinhu zvakasviba uye masaisai egiravhiti ari kukwira.Zvino, mashoko mazhinji anotumirwa nemitumbi yomudenga azova homwe yevazivi venyeredzi, uye chiono chomunhu chiri kuramba chichiwedzera.

Mukutanga kwaMbudzi 2021, mushure menguva refu yekuvandudzwa kweinjiniya uye kuyedzwa kwekubatanidza, iyo yaitarisirwa James Webb Space Telescope (JWST) yakazosvika panzvimbo yekutanga iri muFrench Guiana uye ichavhurwa munguva pfupi iri kutevera.

Kushanda musimboti weteresikopu yenyeredzi:

Nheyo yekushanda yeteresikopu yenyeredzi ndeyokuti chinangwa lens (convex lens) inotarisisa mufananidzo, unowedzerwa nemaziso (convex lens).Iyo inotariswa neicho chinangwa lens uye yobva yawedzerwa ne eyepiece.Iyo chinangwa lens uye eyepiece zvimiro zvakapatsanurwa kaviri, kuitira kuti uvandudze kunaka kwekufungidzira.Wedzera kusimba kwechiedza pachikamu cheyuniti, kuitira kuti vanhu vawane zvinhu zvakasviba uye zvimwe zvakawanda.Chinopinda mumaziso ako chinenge chiedza chakafanana, uye chaunoona mufananidzo wekufungidzira unokudzwa nemboni yeziso.Iko kukudza kona diki yekuvhura yechinhu chiri kure zvichienderana nekumwe kukwidziridzwa, kuitira kuti ive nekona yakakura yekuvhura munzvimbo yemufananidzo, kuitira kuti chinhu chisingaonekwe kana kusiyaniswa neziso rakashama chive chakajeka uye chinosiyanisa.Iyo yemaziso sisitimu inochengeta chiitiko chakafanana danda rinoburitswa mukufambirana kuburikidza neicho chinangwa lenzi uye eyepiece.Kazhinji kune marudzi matatu:

1、 Refraction telescope iteresikopu ine lenzi seyechinangwa lenzi.Inogona kupatsanurwa mumhando mbiri: Galileo telescope ine concave lens seye eyepiece;Teresikopu yeKepler ine convex lens sechinhu cheziso.Nekuda kwekuti chromatic aberration uye spherical aberration yechinangwa chelenzi imwe chakakomba, materesikopu emazuva ano anowanzo shandisa mapoka maviri kana anopfuura.

2, Teresikopu inotaridza teresikopu ine girazi rakakomberedzwa sechinangwa chelenzi.Inogona kukamurwa kuita Newton telescope, Cassegrain telescope uye mamwe marudzi.Mukana mukuru weteresikopu inoratidzira ndeyekuti hapana chromatic aberration.Kana iyo lenzi yechinangwa inotora paraboloid, iyo spherical aberration inogona zvakare kubviswa.Zvisinei, kuitira kuderedza kukanganiswa kwezvimwe zvisizvo, nzvimbo inowanikwa yekuona idiki.Izvo zvinhu zvekugadzira girazi zvinongoda kudiki kuwedzera coefficient, kuderera kushushikana uye nyore kugaya.

3, Catadioptric telescope yakavakirwa pachionioni chakatenderera uye inowedzerwa nerefractive element yekukonzeresa aberration, iyo inogona kudzivirira kuoma kwakakura-aspherical processing uye kuwana yakanaka mufananidzo.Iyo ine mukurumbira ndiyo teresikopu yeSchmidt, inoisa ndiro yeSchmidt yekururamisa panzvimbo yakatenderera yegirazi rakatenderera.Imwe nzvimbo indege uye imwe yacho ikati deformed aspherical surface, iyo inoita kuti chikamu chepakati chedanda chisanganise zvishoma uye chikamu cheperipheral chinosiyana zvishoma, kungogadzirisa spherical aberration uye coma.
