Hutech / Borg 除提供望遠鏡、攝星儀、濾鏡外，配件亦可為愛好者組合不同觀測方案，例如本為APM-TMB平場鏡特製的帶濾鏡盒接環加大通光口徑接環，以下照片除使用APM-TMB 105/650折射鏡外，同時採用不少Hutech / Borg / IDAS元件：

- Hutech 改裝濾鏡 Canon 5D Mark II
- IDAS LPS-V4 52mm 濾鏡
- Borg 濾鏡盒、M57大通光孔徑相機接環

可見照片沒經平場暗場處理，但相機訊噪、像場漸暈並不太明顯。

以下照片則使用APM-TMB 105/650配Borg F4 Super ED reducer拍攝，有效焦距420、光圈F4

小熊好幫手....

第一次用Borg的東西是2000年前後了，當時發現他們的產品意念很好，可以自由組合，那些ED鏡的價格亦不錯，讓好些不能負担頂級APO的同好都能一嘗ED鏡的滋味。

當然Borg的東西絶不是十全十美的，例如其調焦筒，以今天的標準來說已不合時宜，ED鏡也只屬常規水平，外面太多競爭了(新出的瑩石鏡例外)，但個別小配件、導星鏡、改裝相機等都很不俗。現時我比較有興趣是那個松本正像....

自1990年購入第一部私人單鏡反光機Nikon F後，是本年初才購入人生第二部，就是Hutech改裝的Canon 5D Mark II。我很懷疑自己若要再買的，應是以下兩個可能性：

1. 全片幅無鏡單反
2. 可改濾鏡的中片幅單反

没给社长把事情搞砸就好！

博格的 76ED 镜子，一年前见识过，广东南十字的星船（何老大）就用那个，拍出的心脏星云还是不俗。
相比 Τακαhαshi, 它们的配件的说明感觉还比较不错。 最近头痛 FS-78 的Reducer还是难弄到。

迟一会儿我发点 Νικοη F2 相机拍的照片上来。

FS78還是FC76? 不是你用的吧，否則幫你問問。
