Isibhakabhaka sakusihlwa nokugqwala kwelanga
I-catalog yelanga elingokoqobo. Dlulisa isikhombi sokukhanya kokulimala futhi ubone ilanga lihamba.

Isibhakabhaka sakusihlwa nokugqwala kwelanga
Yini lokhu? Izibani zesikhala, amasakhiwo namaphawu enza izulu lemini likhanya, futhi lesi sibhakabhaka sifihla izinkanyezi ezincane. Lezi zisetshenziswa zibonisa izinkanyezi zomuntu siqu kusuka ku-star catalog kanye nokuthi zingaki ezihamba kancane njengoba izulu likhanya, kusukela endaweni emnyama kakhulu kuya ezindaweni ezisephakathini zomgwaqo.
Indlela yokusetshenziswa kwayo: Khetha incazelo efana kakhulu nezulu lakho, noma cindezela isici sokususa uthuli lwesibani. cindezela isithombe sezulu ukuze ubheke ngaphesheya.
Ingabe isibhakabhaka sakho simnyama?
Khetha enye ezwakala njengezulu lapho uhlala khona. Isithombe ngasinye sibonisa ama-stars we-Orion ongayibona kulo nqanaba.
Izimo zesibhakabhaka kanye nokukhanya kusuka ku-Yale Bright Star Catalogue. Indawo yakho ayikho egcinwe.
Zama lokhu
- Qala ku level 1 (indawo emnyama kakhulu) bese usuka kancane kuze kube yi-9.Isixhumanisi: Kusuka ezinyangeni eziyi-9,000 ezidlulayo ezulu lonke, cishe ama-400 kuphela asele ezindaweni zedolobha, futhi inhlamvu eyodwa kuphela yezulu iphezulu kwakho nganoma yisiphi isikhathi.
- Khetha i-Orion bese uqhathanisa amanqanaba angama-4 nama-8.Isixhumanisi: Uhlobo oludumile luhlala, kodwa ama-stars amnyama agcwalisa ngalo, kanye ne-Milky Way ngasemva kwayo, iphela.
- Ngobusuku obulandelayo obucacile ngaphandle kwenyanga, phuma ngaphandle kude nelanga eliqondile bese ulinde imizuzu engu-20 ukuze amehlo akho alungele.Isixhumanisi: Thola isithombe lapha esifana nalokho okubonayo: lokho kuyinhlanganisela yezinga lakho le-Bortle. Izithombe zibonisa indawo ye-Orion; noma yiliphi iqembu elijwayelekile lamaplanethi lisebenza.
Izinhlamvu ezimqoka
Ingabe umuntu angakwenzani?
Ukulimala kwelanga kunzima kakhulu ukuxazululwa: cindezela uvala bese kudlula. Nciphisa izibani zangaphandle futhi uzikhusele, sebenzisa ama-bulbs akhanyayo, futhi uvale izibani ezingadingeki ngumuntu.
Amasu: izimo zesibhakabhaka kanye nokukhanya kusuka ku-Yale Bright Star Catalogue (5th revised edition). Amazinga ezulu namaplanethi abonakala kancane kakhulu kusuka ku-J. I-E Bortle, "Ukusungula i-Bortle Dark-Sky Scale", Izulu & Telescope, Februwari 2001. Usizo lokukhangisa: DarkSky International. Indawo yakho ayikho ecelwe noma igcinwe.
Ukukhanya okungenziwa kwenziwa okukhanya lapho akudingeki khona, ikakhulukazi ezulu. Kukwenza izulu lonke likhanya futhi lifihla amakilasi.
Okuningi ku-glossary →Isikali se-1 kuya ku-9 sokuthi izulu limnyama kangakanani, elishicilelwe ngu-amateur astronomer uJohn E. Bortle ngo-2001. Izinga 1 yizulu elimnyama kakhulu emhlabeni; izinga 9 liphakathi komgwaqo.
Okuningi ku-glossary →Isikali abacwaningi be-astronomia basebenzisayo ukukhanya. Amanani amakhulu kuthetha amnyama: amaplanethi akhanya kakhulu aphakathi kwe-magnitude 0 noma 1, futhi amnyama kakhulu ongabona kuwo kusuka endaweni emnyama kakhulu yi-magnitude engu-7 kuya ku-8.
Okuningi ku-glossary →Amazinyo akho aqala ukucasuka ngokucophelela lapho kumnyama. Kuthatha imizuzu engu-20 kuya kwengama-30, futhi ukubuka okukodwa kwesikrini esikhanyayo noma isibani sizosusa ingxenye enkulu yalokho.
