ブランドン BRANDON 32mm EFL アイピース

マクストフ望遠鏡の最高峰QESTAR(クエスター)の付属品としても有名なVERNONscope(バーノンスコープ)社製のBRANDON(ブランドン)32mmアイピースのレアなショートモデルです。



ブランドンは、1971年にクエスターの標準付属品に指定されてからその高性能が注目されたアイピースです。現行品でもあり、国内では国際光器が輸入し、協栄産業やスターベースで税込51,480円~70,180円で購入可能です。



こうした現行品はパーフォーカル化されて細長い筐体に収められていますが、このモデルはアイレンズ近くまでスリーブに差し込めるため、対物の筒外焦点が短い反射望遠鏡や天頂プリズムや正立プリズムを介しても(あるいは延長光学系を仕様しなくても)合焦しやすい仕様になっています。



レンズ構成は2群4枚ですが4枚の硝材や曲率ともに異なるこだわった設計で、フランスのクラべと双璧をなすプローセスアイピースです。

米国カンパニーセブン社のサイトからの引用によれば、「ブランドン・アイピースの設計と構造は、1930年代後半にカール・ツァイス社でアルバート・ケーニッヒ(1871-1946)と彼のチームが設計したプローセルの設計に似ていますが、クエスター・ブランドンの性能は、エルンスト・アッベ(1840-1905)が設計したオルソスコピック接眼レンズに近いものです。歪みがなく、高コントラストと優れた鮮明度を誇ります。」とあります。



赤い外箱と前後のキャップが付属します。なお、全体に比較的きれいですがあくまで中古ですので、完璧なものにこだわる方はご購入をご遠慮ください。
