    Cons: Quite heavy so not the best to carry round on a hike. Never heard of them before

    Pros: Great optics, really good in low light, I really noticed this star gazing comparing against Bushnell Legends, there were many more stars visible with the Bynolyts. Contrast and colours are also very good with only very slight fringing present with strongly back lit subjects. Again this was not as evident as on the Bushnells.

    Summary: Really pleased I discovered these and only did so through RSPB otherwise I still do not think I would have heard of Bynolyt which is a great shame.
