ED element 低色散元件

These latest designs from Takahashi incorporate the classic Abbe Orthoscopic master lens groups with a new ED-glass doublet to produce an ultra-high contrast, high resolution eyepiece with longer eye-relief and considerably more comfort than traditional Abbe lenses. All air-glass surfaces are multicoated for maximum light transmission and contrast. Both the 3.6mm and the 2.8mm have six elements in three groups and an apparent field of 40 and 42 degrees respectively. Color correction is superb and off-axis aberrations are essentially non-existent. These eyepieces are designed to allow the owner of a SKY-90, FSQ-106 or TOA-130 to obtain the higher magnifications required for high resolution planetary and double star observations without sacrificing contrast or image quality.

高橋最新設計產品將超低色散玻璃使用在傳統 Abbe Orthoscopic 鏡片組合中, 故其所得影像為超高反差, 高解像度及較長眼視點, 使用時較傳統設計的 Or 目鏡更為舒適. 所有接觸空氣鏡面均為多層鍍膜. 3.6mm 與 2.8mm 為 6 枚 3 組鏡片式設計, 視場為 40 及 42度. 極高矯色能力及不存在離軸偏差. 這兩款目鏡特別適合配套於 Sky-90 FSQ-106 或 TOA-130 於超高倍數觀測行星及雙星時, 反差及影像仍沒有變質.
