Offre inoltre una migliore protezione dai raggi UV rispetto ai semplici filtri in vetro.\u003c\/p\u003e\u003cp\u003eCon il manuale allegato, tutti possono costruire il proprio filtro per il telescopio astronomico in pochi minuti. Il Baader Astro Solar Foil è stato premiato come prodotto astronomico del decennio negli Stati Uniti. Le seguenti caratteristiche hanno reso possibile questo risultato? Protezione ottimale: La pellicola è ricoperta su entrambi i lati da uno strato filtrante, non solo su un lato.\u003c\/p\u003e\u003cp\u003eOgni strato può contenere microfori che aggirano i raggi UV. Con uno strato su entrambi i lati, questo non è più possibile? Eccezionale qualità ottica: Il foglio Astro Solar ha prestazioni ottiche superiori a quelle dei fogli di Mylar, ad esempio. Questo è stato dimostrato da un test indipendente. Anche rispetto ai filtri in vetro, la pellicola Baader è superiore: in ogni sezione, ha prestazioni limitate dalla diffrazione. Inoltre, la pellicola è neutra dal punto di vista cromatico. Non dà colori verdi o gialli. Molto resistente: Un filtro di vetro può rompersi e una lamina può strapparsi. Ma il Baader Astro Solar Foil, grazie alla sua speciale struttura molecolare, è estremamente rigido.\u003c\/p\u003e\u003cp\u003eIl colore del sole attraverso la pellicola Il sole è rappresentato in una tonalità neutra di bianco freddo. È una favola che il sole appaia in blu. La tonalità neutra consente visioni ricche di contrasto e viene descritta da molti osservatori come \"molto piacevole\". Soprattutto ad alti ingrandimenti, consente osservazioni di successo.\u003c\/p\u003e\u003cp\u003eAlcuni astronomi preferiscono un colore arancione o giallo caldo. Questo colore non rappresenta la realtà e, dal nostro punto di vista, non è ottimale per il massimo contrasto e i dettagli più fini, ma in combinazione con questa pellicola di colore neutro, si possono fare esperimenti con diversi filtri colorati e scegliere il migliore. In questo modo non si è vincolati a un solo colore. Un esempio per uso fotografico: Questo gruppo è stato ripreso con il Baader Foil (versione fotografica) e un filtro Baader Solar Continuum. Strumento: Rifrattore acromatico TS 127\/1200 mm. Immagini ad alta risoluzione come questa sono possibili solo con un buon obiettivo e un buon filtro solare.\u003c\/p\u003e","brand":"Baader","offers":[{"title":"Default Title","offer_id":51120701735128,"sku":"2718","price":26.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0766\/0722\/6072\/files\/20d6eca39326b9b6d1230ef3ea343b9c.jpg?v=1764069972"},{"product_id":"baader-planetarium-occhiali-occhialini-con-filtro-astrosolar-nd5-0","title":"Baader Planetarium Occhiali Occhialini con Filtro AstroSolar ND5,0","description":"\u003cdiv\u003e\n\u003cp\u003e\u003cspan style=\"font-family: Silka Light, monospace;\"\u003e\u003cspan style=\"font-size: small;\"\u003eGli occhiali Baader Planetarium Solar sono lo strumento indispensabile per la visione del sole, per occasioni particolari e rare come un'eclissi parziale, totale o anche per la visione di grandi macchie solari.

The emission line displays areas of Super Granulation Cells that are brightest and strongest in areas of high magnetic fields such as sunspot activity and active regions.
