Hinweis:<\/strong> Die hier gezeigte Sonnenprojektion erfolgt mit einem historischen Refraktor samt Projektionsschirm. Diese Methode eignet sich nicht f\u00fcr jedes Teleskop. Je nach Bauart, verwendeten Materialien und Herstellerangaben k\u00f6nnen optische Bauteile durch die starke W\u00e4rmeeinwirkung besch\u00e4digt werden. F\u00fcr die Sonnenbeobachtung empfehlen wir heute in der Regel Sonnenfilter vor der Objektiv\u00f6ffnung oder speziell daf\u00fcr entwickelte Sonnenteleskope.<\/p>\n","protected":false},"excerpt":{"rendered":"
