Night Sky ndi Kuwononga Kwamawala
Kodi ndi chiyani? Maola a usiku amawoneka ngati akuwala chifukwa cha magalimoto, nyumba ndi zilembo. Ndipo mwangawu umateteza miyala yofiira yomwe siyioneka bwino. Izi zimasonyeza miyala yachilendo kuchokera ku katalagala ya miyala komanso kuti zingati zomwe zimatuluka pamene mdima umakhala wowala kwambiri, kuyambira pamalo oyera mpaka m'mphepete mwa mzinda.
Momwe mungagwiritsire ntchito: Sankhani mawu omwe amafanana kwambiri ndi nyanja yanu, kapena dinani slider ya kuwala kwa nyanja. Dinani chithunzi cha nyanja kuti muwone pansipa.
Kodi nyanja yanu ndi yofiira bwanji?
Sankhani chithunzi chomwe chimawoneka ngati nyanja ya kumwamba komwe mumakhala. Mzere uliwonse umasonyeza mafumu a Orion omwe mungaone pamalo amenewo.
Malo a nyenyezi ndi kuwala kwawo kuchokera pa Yale Bright Star Catalogue. Malo anu sachitiritsidwanso.
Pezani izi
- Kuyambira pa level 1 (a sitebe kwambiri) ndi mofulumira drag kuti 9.Kudziwitsa: Kuchokera pa nyenyezi zoposa 9,000 m’nyanja yonse ya kumwamba, pafupifupi 400 zokha ndizo zomwe zili m’mizinda, ndipo ndi theka la dziko lapansi lokha lomwe lili pamwamba panu nthawi iliyonse.
- Sankhani Orion ndi kuyerekezera maphunziro 4 ndi 8.Kudziwitsa: Mtundu wodziwika bwino umapulumuka, koma ziwanda zofiira zomwe zimazidzaza ndi Mdima wa Milky Way m'mbuyo mwake, zimafa.
- Pa usiku wotsatira womwe udzakhala wosawala, pitani kunja mopanda kuwala kokhako ndipo muyembekezere mphindi 20 kuti maso anu azimve bwino.Kudziwitsa: Pezani chithunzi chomwe chikugwirizana ndi zomwe mumaona: izi ndi zofanana ndi Bortle level yanu. Zithunzizi zikusonyeza malo a Orion; chilichonse chodziwika bwino cha ma stellar group chimagwira ntchito.
Maganizo m'mbuyomu
Kodi wina angachite chiyani?
Kuwononga kwa dzuwa ndi vuto lovuta kwambiri kuchotsa: tsegulani ndipo lidzatha. Sungani mabala akunja ndikuwateteza, kugwiritsa ntchito mabafa otentha komanso kuletsa mabala omwe palibe amene amafuna.
Kuchokera: malo a nyenyezi ndi kuwala kwazo kuchokera ku Yale Bright Star Catalogue (5th revised edition). Madera a nyanja ndi mafilimu owoneka bwino kwambiri a ku J. E. Bortle, "Introducing the Bortle Dark-Sky Scale", Sky & Telescope, February 2001. Umboni wa kuwala: DarkSky International. Malo anu safunsidwa kapena kusamalidwa.
Mdima wopangidwa ndi munthu womwe umawala pamene sikuti uyenera, makamaka kumwamba.Izi zimachititsa kuti nyanja yonse ya usiku ikhale yobiriwira komanso imafikira magombe.
Kuwonjezera pa mawu ofotokoza →Mtengo wa 1 mpaka 9 wosonyeza kuti nyanja ya usiku ndi yofiira bwanji, yomwe inatulutsidwa ndi munthu amene amadziwa za kuwala kwa dzuwa John E. Bortle in 2001. Level 1 ndi nyanja darkest pa dziko lapansi; level 9 is a city centre.
Kuwonjezera pa mawu ofotokoza →Zina zambiri zikutanthauza kuti ndi zofiira: ziwanda zofiira kwambiri zili m'mawu a 0 kapena 1, ndipo zomwe mungawone kuchokera pamalo oyera kwambiri ndi za mawu a 7 mpaka 8.
Kuwonjezera pa mawu ofotokoza →Maganizo anu amayamba kukhala olimba mtima m’chithunzipo. Zimatenga maola 20 mpaka 30 kuti mukhale ndi chisoni. Mtima wanu umachita zinthu zambiri chifukwa cha kuwala kwa foni kapena chowunikira.
Tabula ya deta (malemba osiyanasiyana)

Zipangizo ndi zitsanzo zimagwiritsa ntchito mapangidwe osinthidwa kuti aziphunzira okha. Sayenera kugwiritsidwa ntchito poyendetsa, kupanga miyezo kapena kukhazikitsa njira iliyonse yogwiritsira ntchito. Onani zoletsa za masamba ophunzitsa
