2024年12月13日発売! 7.5 x 50 ファインダー 黄・限定色【KA00555Y】

 

※ 黄色は限定での販売となり、在庫払底で終了となります。

 

販売終了となっていた7×50ファインダーの後継品です。

新型のファインダーが仕様を新たにして新発売となりました。

 

口径は旧機種と同じ50mmですが倍率は7.5倍、 実視界は6°に変更となっています。

対物側と接眼側にはヘリコイド式の調整機構を採用し、ピント位置や視度の細かな調整が可能です。鏡筒径は旧製品と同じφ53mmなのでファインダー脚(別売)は従来のものがそのまま使用出来ます。

 

また、接眼部を取り外して今後発売予定の「GTマウントアダプター」に交換することで、31.7mm差し込みのガイドカメラや接眼レンズを取り付けることも出来るようになり、ガイド鏡として使用することなども可能です。※ただし天頂プリズムは併用できません。

 

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

 昨今の天体観察環境では自動導入が普及し、ファインダーは以前ほどの広視野が必須ではなくなりつつあります。夜空が明るくなったことでファインダーの倍率は高い方が見やすい場合が多くなりました。こうした背景を鑑み、本製品では対物レンズの焦点距離を従来品よりも長い焦点距離212mm/F4.2として、接眼レンズと組み合わせた全体で7.5倍の設計としました。
 対物レンズの焦点距離を長くしたことで、結像性能は従来品と比較して大幅に向上しており、眼視感度の高い500~600nmの範囲を重点的に補正する光学設計により、ファインダーの対物レンズとしては異例の眼視ストレール比約70%を実現しています。
