Uyini umehluko phakathi kwesibonakude se-refractor nesibonakude se-reflector?
Isibonakude se-refractor sisebenzisa ama-lens ukuze sigxilise ukukhanya esithombeni kuyilapho isibonakude se-reflector sisebenzisa izibuko. Ngokuvamile izibonakude ezibonakalisa ukukhanya zingcono ekubukeni izinto ezikhanyayo zasezulwini njengenyanga noma amaplanethi futhi zingakwazi ukuqoqa ukukhanya okwengeziwe ngenxa yokuvuleka kwazo okukhulu. Izibonakude ze-refractor zinikeza umehluko ongcono nekhwalithi yesithombe kodwa ziqoqa ukukhanya okuncane okuzenza zilungele kakhulu i-astrophotography lapho isikhathi sokuchayeka singalungiswa ukuze sinxephezele.
