Lub koob yees duab yog ib qho khoom siv kho qhov muag siv los saib xyuas cov khoom nyob deb ntawm qhov chaw, tab sis muaj ntau yam uas tuaj yeem ua rau lub tsom iav sib txawv ntawm ib leeg. Nov yog qee qhov tseem ceeb uas tuaj yeem sib txawv ntawm telescopes:
Optical Design: Telescopes tuaj yeem muaj cov qauv kho qhov muag sib txawv, xws li refracting telescopes lossis reflecting telescopes. Refracting telescopes siv lo ntsiab muag los sib sau ua ke thiab tsom teeb pom kev, thaum lub teeb tsom iav siv iav. Qhov kev xaiv ntawm kev tsim kho qhov muag tuaj yeem cuam tshuam rau yam xws li duab zoo, thaj chaw saib, thiab qhov loj ntawm lub tsom iav.
Aperture: Lub aperture ntawm lub tsom iav raj yog hais txog txoj kab uas hla ntawm nws cov thawj qhov muag pom, uas tuaj yeem yog lub lens lossis daim iav. Aperture txiav txim siab lub teeb sib sau lub zog ntawm lub tsom iav raj. Telescopes nrog apertures loj tuaj yeem sib sau ntau lub teeb, ua rau lawv saib cov khoom fater thiab muab kev daws teeb meem zoo dua.
Focal Length: Lub focal ntev yog qhov kev ncua deb ntawm cov thawj qhov muag pom thiab qhov chaw uas cov duab tsim. Nws cuam tshuam qhov kev nthuav dav thiab thaj chaw ntawm kev pom ntawm lub tsom iav. Telescopes nrog ntev focal lengths muab kev nthuav dav dua tab sis nqaim ntawm qhov pom.
Mounting System: Telescopes xav tau cov tshuab mounting ruaj khov los txhawb thiab tswj lawv cov kev txav. Muaj ntau hom mounts, xws li alt-azimuth (nce-down, sab laug-txoj cai) thiab equatorial (raws li lub ntiaj teb axis) mounts. Qhov kev xaiv ntawm mount cuam tshuam qhov yooj yim ntawm kev taug qab cov khoom saum ntuj thiab kev ruaj ntseg thaum saib.
Accessories: Telescopes tuaj yeem nruab nrog ntau yam khoom siv los txhim kho lawv txoj haujlwm. Piv txwv suav nrog eyepieces ntawm qhov sib txawv focal lengths rau kev hloov magnification, finderscopes los nrhiav cov khoom, cov ntxaij lim dej los txhim kho cov wavelengths ntawm lub teeb, thiab astrophotography txuas rau kev ntes cov duab.
Portability: Telescopes tuaj yeem muaj qhov loj thiab qhov hnyav, cuam tshuam rau lawv txoj kev txav mus los. Cov koob yees duab me me feem ntau nqa tau yooj yim dua thiab yooj yim rau kev thauj mus los, thaum lub koob yees duab loj dua feem ntau muaj peev xwm sib sau ua ke ntau dua tab sis tej zaum yuav nyuaj dua kom txav mus los.
Lub Hom Phiaj: Telescopes tuaj yeem tsim rau lub hom phiaj tshwj xeeb. Qee lub telescopes yog optimized rau kev pom kev pom, thaum lwm tus yog tsim los rau astrophotography los yog kev tshawb fawb tshwj xeeb. Lub hom phiaj npaj tuaj yeem cuam tshuam cov kev xaiv tsim, nta, thiab cov ntsiab lus ntawm lub tsom iav.
Cov xwm txheej no, ntawm lwm tus, ua rau muaj kev sib txawv ntawm lub tsom iav raj muaj rau cov kws tshawb fawb thiab cov neeg nyiam, tso cai rau lawv xaiv cov cuab yeej tsim nyog tshaj plaws rau lawv cov kev xav tau tshwj xeeb thiab nyiam.
