FL55SS鏡筒がF4.3高性能アストログラフへ!

FL55SS鏡筒用の高性能フラットナーレンズとレデューサーレンズおよび接続リングのセットです。像面の平坦化により写真性能が向上、また焦点距離を約0.79倍に短縮します。

※フラットナーとは
通常の光学設計では写野周辺に収差が発生し、点像が流れて写ります。フラットナーはそのような収差を補正し、写野周辺までしっかりと星を点のままで撮影するための補正レンズです。

※レデューサーとは
望遠鏡の焦点距離を短くし、F値を明るくする補正レンズです。天体撮影の構図にバリエーションが広がります。

 

Vixen 天体望遠鏡 レデューサーHDキット for FL55SSの特長

 

① フルサイズ一眼カメラの写野全面シャープな星像

フラットナーHD for FL55SSはFL55SS鏡筒の焦点距離変化を最小限に抑えつつ直焦点による平面性を改善、写真性能が大幅に向上します。イメージサークルΦ44mmを確保、フルサイズ一眼カメラの写野をカバーできます。また、セットに含まれるレデューサーHD5.5との併用によりイメージサークルΦ44mmを維持しながら焦点距離を約0.79倍に短縮(F5.5→4.3)。さらにシャープネスも大幅に向上、フルサイズ一眼カメラの写野全面にわたり鋭い星像が得られます。

 

② フルサイズ一眼カメラ周辺端で「最大周辺光量96%」を達成!

初心者でも気軽に天体撮影を楽しめるよう、「周辺光量の豊富さ」にこだわって設計されたのが、FL55SS専用フラットナー&レデューサーのセット「レデューサー HD キット for FL55SS」です。

「レデューサー HD キット for FL55SS」使用時は、フルサイズ一眼レフ周辺端で「周辺光量86%」を達成。60%以上の周辺光量があればイメージサークルとして成立することを考えると、余裕の明るさが得られ、前述の「フラットフレームによる補正」などの画像処理をしなくても周辺光量が豊富な画像を得られます。

また、「レデューサー HD キット for FL55SS」に付属の「フラットナーHD for FL55SS」のみを使用した場合、フルサイズのイメージサークルΦ44mm端でもほぼ完璧に近い「周辺光量96%」の確保に成功しました。 この値はイメージサークルの端いっぱいでの値ですから、実際にフルサイズ一眼カメラで撮影すれば周辺光量低下を殆ど感じない画像が得られます。

これにより撮影後の画像処理を大幅に簡略化することも可能となり、より気軽に星雲・星団の天体撮影が楽しめるようになりました。

フルサイズ・APS-Cについて

一眼カメラにおける受光部平面(センサーまたはフィルム)の大きさ形状を表すサイズの通称です。主なサイズとしてフルサイズ(36×24mm)、APS-C(23×16mm)、フォーサーズ(17.3×13mm)があります。カメラ機種により多少の違いがありますので、詳しくは市販のカメラ説明書、カタログ等にてご確認ください。一般に受光部平面が大きいほど広い範囲を撮影できます。
