## Customer Reviews

### ⭐⭐⭐⭐⭐ 使い方
*by Y***I on May 12, 2019*

ボール紙で枠を作ってそれをCokin フィルターアクセサリーのフィルターアダプターに装着して使用してます。使い心地は結構良いと思います。

### ⭐⭐⭐⭐⭐ とても良い商品です。
*by 主***０ on January 2, 2018*

８センチと５センチの望遠鏡用に購入しました。主鏡フードに段ボールで加工して取り付けました。安価で良い商品です。

### ⭐⭐⭐⭐⭐ 太陽が自然な色に写ります
*by T***N on September 21, 2016*

自然な色といっても太陽を直視できるわけではありませんが、スペクトル的にはオレンジ色です。バーダー社のものだとピンク色になり、各社のD5フィルターだとグレーになる上目視での使用は不可です。薄いですが樹脂でありピントやコントラストに影響するかと思いましたが、他のフィルターとその点で差は無いと思います。あとは材質的な耐久性ですが、安価なので劣化したと思ったらすぐ買い替えるのが良いでしょうね。薄いプラ板のようなものなのでサークルカッターで円形に切り、望遠鏡のフード内にきっちりはめて使っています。
