D\u00e4refter riktades den vridbara m\u00e4tlinjalen (alidada) mot solen eller en stj\u00e4rna. P\u00e5 den satt tv\u00e5 plattor med h\u00e5l. N\u00e4r man observerade solen tittade man inte direkt genom siktet - solstr\u00e5len skulle helt enkelt passera genom b\u00e5da h\u00e5len samtidigt. N\u00e4r man observerade en stj\u00e4rna, oftast Polstj\u00e4rnan, siktade man direkt genom dem. D\u00e4refter avl\u00e4ste man himlakroppens h\u00f6jd i grader p\u00e5 instrumentets graderade skala.<\/p>\n        <p class=\"text-left\">Latituden best\u00e4mdes genom att kombinera solens uppm\u00e4tta middagsh\u00f6jd (n\u00e4r den stod som h\u00f6gst) med uppgifter fr\u00e5n astronomiska tabeller. P\u00e5 natten p\u00e5 norra halvklotet var det \u00e4nnu enklare, eftersom latituden n\u00e4stan direkt motsvarade Polstj\u00e4rnans h\u00f6jd.<\/p>\n        <p class=\"text-left\">En klassisk, solid skiva skulle dock f\u00e5nga vinden ombord och gunga hela tiden. Sj\u00f6mansversionen fick d\u00e4rf\u00f6r formen av ett l\u00e4ttare hjul med utsk\u00e4rningar och en tyngre nedre del som h\u00f6ll det stabilt i lodr\u00e4tt l\u00e4ge. Astrolabiet var visserligen mindre exakt \u00e4n den senare sextanten och kunde bara m\u00e4ta vertikala vinklar, men det r\u00e4ckte l\u00e4nge gott och v\u00e4l f\u00f6r navigering p\u00e5 \u00f6ppet hav.<\/p>\n        <p class=\"text-left\">Den h\u00e4r modellen \u00e4r en replika av det s\u00e5 kallade valencianska astrolabiet fr\u00e5n 1500-talet, uppkallat efter den irl\u00e4ndska \u00f6n Valentia. Originalet tillh\u00f6rde den spanske kungen Filip II:s flotta. Det uppt\u00e4cktes 1845 och f\u00f6rvaras i dag p\u00e5 National Maritime Museum i Greenwich.
