    25-50x eyepiece diameter?

    Hi Northman I see you have had no replies to your enquiry. I suspect that you may have found the answer elsewhere by now, but I have recently acquired an ATS80 with a 25-50x eyepiece, and I have just measured the diameter at 52mm. Cheers

    Fuji XF 70-300 f/4-5.6

    The new 70-300mm lens is an excellent addition to the Fuji XF lens line-up. The fact that the 1.4x 7 2x TCs can be used with it adds a valuable extra dimension. Since I obtained my copy it has been my most used lens.

    What to use when your 8x binoculars aren't powerful enough?

    Nikon ED50 (or similar) with 16x or 20x eyepiece plus a shoulder pod might be an option.

    Bird species seen just the once in your yard/garden.

    I had a Black Redstart (Phoenicurus ochruros) on my shed roof in my suburban Sussex garden a few years ago - stayed for about 10 seconds.

    When you install the Swarovski head rest should you hear a click?

    SF 8x32 v NL Pure 8x42

    Thanks for that information - very helpful. As you also say, weight is a major consideration. I hope to be able to try both models before too long.

    SF 8x32 v NL Pure 8x42

    I know that the lack of reference to Swaroclean on the NL Pure has been touched on briefly in another thread, and I am also aware that it is a coating that perhaps has no meaningful effect on the optical performance (hence may not have been identified as present by Swarovski in their technical...

    Many thanks - very helpful.

    Beetle ID

    Actually, I am now inclined towards this being one of the Flea Beetles in the genus Altica. Any thoughts from others would be most welcome.

    Beetle ID

    Hi All I am looking for an ID on this specimen, seen in West Sussex today. I suspect that it might be a Blue Mint Beetle, Chrysolina coerulans and I would be most grateful for a confirmation or correction as appropriate.

    ED50 20x or 27x DS question

    I have an ED50A (as well as an ED82A) and I use mine almost exclusively as a travel scope. I use a 20w for 95% of the time but I also take a 40x/75x (old style MC with fold-down eyecup) and use it for more distant viewing as required.
