Fujinon Polaris 10x50 FMTR-SX Binocular

These are excellent astronomy binoculars. After 10 years I finally own one of these. The image is sharp to almost the edge and field is flat. On-axis sharpness, contrast and transmission is excellent. I easily see more stars compared to my previous 10x42 Nikon binoculars even in light polluted places. Furthermore, these binoculars are very ruggard and I like the fact that I can just 'dump' it into my luggage bag without worrying that it get damaged. Being rubber armoured, it is not necessary to have a case. The only draw back of this binoculars for astronomy applications is the weight. If one needs to observe for long hours, it can get a bit strenous. However, to alleviate this, I use this binoculars in conjunction with my monopod. In this way, I achieve better stabilization (much less body/ hand shake and thus higher resolution) and way less fatigue to my arms. :)

These are excellent marine binoculars, well built and excellent optics. One caveat is that the binoculars are heavy and can be hard to hold up for long.
