55FL Cutaway & Hinode Constellation Bino

I was not sure I published the lens cutaway of 55FL F3.6 optical system before. So I posted here now.

cutaway

Total 6-element system including a front fluorite. I will publish new 107FL F3.9ED as well sometime soon. Current BORG astrograph systems use not only fluorite or ED, but also special elements and shapes to maximize total performance. These are BORG-proprietary unique optical design.

Hinode super wide bino are now in stock. It will be available through Hutech dealers worldwide.
