Antlia SII EDGE ナローバンドフィルターは、FWHM(半値全幅)を4.5nmのバンドパスに最適化します。

Antlia 3nm Proシリーズで採用されている不要波長の光学濃度(OD)5の抑制と優れた透過率特性が、4.5nm EDGE 狭帯域フィルターにも組み込まれています。その結果、これらのフィルターは優れたSNR(信号対雑音比)と優れたコントラストを実現します。

 

Antlia SII 4.5nm EGDE フィルターは、656.3nmで高い透過率を実現するように設計されており、最大の信号強度でSII星雲の最も微弱な構造を捉えます。

従来のブロードバンドナローバンドフィルターは、中心波長(CWL)の大きなシフトにより、透過率に大きな損失を生じます。

この製品は中心帯域幅から1nmの範囲内でT>90%を保証しています。

これは、SII 4.5nm EDGEナローバンドフィルターが、長焦点・F値の小さい光学系の両方で高い透過率を保証できることを意味します。

青方偏移データによると、Antlia 4.5nm EDGEフィルターは、f/3までのほぼすべてのシステムで発光信号の損失を最小限に抑えながら使用でき、高速光学系の要件を満たしています。

 

<製品の特長>

・高い透過率と 4.5 nm のナローバンド域によりコントラストを最大化します。

・急峻なスペクトル プロファイルにより、明るい星の周りのハローが減少します。

・内部反射を排除する単一の基板を採用。

・光害のある場所や暗い場所の両方での天体撮影用に設計されています。

・星雲、惑星状星雲、超新星残骸のSII 領域の撮影に適しています。

・月が出ているときの撮影時間を延長します。

・優れた光学信頼性により、画像処理後の処理を軽減します。

・このフィルターは、SII領域を含まない対象には適していません。銀河のSII領域を撮影するために使用でき、これらの画像をLRGB画像に合成することで、銀河のSII領域をより鮮明に強調することができます。

 

■保証

 ・3年保証(剥離に対して)
 

■注意事項

 ・太陽の観測と撮影には利用できません。

 ・眼視観測には利用できません。

 ・ANTLIAフィルターを装着した状態で太陽を見ないでください。

 ・警告に従わない場合、深刻な眼の損傷につながる可能性があります。
