Fujinon 10x50 FMTR-SX-2 Binoculars

The Fujinon 10x50 FMTR-SX-2 is very interesting especially because because it can be used very universally and because of its compact size, it can be used hand-held even for prolonged periods of time. Especially if the binocular is not only intended for astronomical observation but also for other usages, this may be interesting. The Fujinon 10x50 FMTR-SX-2 has an exit pupil of 5 mm which is very effective for the average user. This is true because a normal Eye can use the full 50 mm objective lens diameter during night time observation, whereas greater Objective lenses and a resulting greater exit pupil might not be supported by the observer's eye, so that there would be no additional advantage. All around a very nice piece of equipment!
