輝線星雲、惑星状星雲、超新星残骸の撮影に最適なHα 3nmフィルターです。Hα線を放射する星雲において、非常に多くのディテールを鮮明に捉えることができます。

Hα線以外の光はほとんど透過しないため、より長い露光時間、より大きな絞り、またはより速い焦点比が必要となる場合があります。

3nmという極めて狭い帯域幅により、光害の大きい場所からの天体撮影が可能になり、暗い場所でもHα線を放射する星雲のコントラストを向上させます。

 

中心波長656.3nmで88%もの高い透過率を実現します。このフィルターは、他の波長や特に人工水銀灯や人工ナトリウムランプからの干渉を効果的に抑制します。

 

帯域外遮断性能はOD5(0.001%)と評価されており、優れたS/N比と効果的なカットオフレートを実現し、他の波長からの干渉を最小限に抑えます。改良されたシャープカットの天体写真用3nm Proフィルターは、明るい星の周りのハローを最小限に抑えるように設計されています。

 

<製品の特長>
・高い透過率と 3.0 nm の超狭帯域幅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。

・AntliaナローバンドProフィルターは、信号損失を最小限に抑えながら、f/3システムまで使用できます。

・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。

・月が出ているときの撮影時間を延長します。

・星雲、惑星状星雲、超新星残骸の Hα 領域の撮影に適しています。

・すべての Antlia ナローバンドフィルターは、迷光による干渉を最小限に抑えるためにエッジを黒く塗られています。

・優れた光学的信頼性により、画像処理の負担が軽減されます。

・このフィルターは、Hα領域を含まない対象には適していません。銀河のHα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Hα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。
