By The Way Yours Have A Green Colour On The Objective ? Maybe Have Some Time And Make A Clear Pictures In Order To See The Real Colour Of The Objective
Yes. The coating is deep green colour (see picture in thumbnail). I guess the STP stands for Swarotop? I read Habicht built after 2011 are coated with the latest coatings that gives 96% transmission. It's even rivalling my fully multi coated 7x50 at night. Perhaps a Habicht 10x40 can beat any 7x50 bino?
If one can just find the right belt with thread marks.. it can be put in front to control the two eyepieces.. maybe adding a motor with big torque.
