    iPhone 14 Pro Digiscoping Review

    I picked up an iPhone 14 Pro and PhoneSkope adapter and compared digiscoping quality with my Full-Frame Sony a9 and 40/2.5 digiscoping rig, and to my professional Sony a1 and 600/4 rig. In short, the iPhone 14 Pro does an impressive job of creating high resolution images that are easily...

    Digiscoping w/ the Sony Cybershot DSC-RX100 III

    I've been playing w/ the new Sony RX100 III camera the past few days in the yard. The new Zeiss 24-70mm f/1.8-2.8 lens is very sharp, and the new pop-up EVF is very nice, as well. I especially like the focus-peaking capability and Auto-ISO features. Noise properties are very good, as well...

    Blue-eyed Herring Gull, Waterford - Unusual?

    I was in Waterford last week and photographed this (presumed) Eurasian Herring Gull (L. argentatus) and noticed it had blue eyes. Is this unusual? All other Herring Gulls I'd seen to this point in Ireland had the typical yellow eyes. Any comments?

    Cliffs of Moher, Ireland in August - seabirds?

    Homemade adaptor for Coolpix P6000 and Zeiss 40X eyepiece

    I've just received the 'New' Zeiss 30X/40X Fixed Eyepiece for my 'Old' Zeiss Diascope 85T*Fl. There have been questions raised as to whether this eyepiece will fit older model scopes - the answer is YES! It snaps in just like my 20-60X Zoom Eyepiece does on the scope and makes a secure fit.

    Kumlien's Iceland Gull? - Port Huron, MI USA

    Need a confirmation on this bird. The slate wingtips suggest Kumlien's, and white head (adult breeding?), relatively small bill, pale yellow eyes w/o distinct red orbitals, and long wing projection look good for Iceland, but the pale legs are throwing me. I don't see enough of these birds to...

    First-cycle Lesser Black-backed Gull?- Monroe, MI USA

    I digiscoped this individual in heavily overcast skies this past weekend and suspect it to be a Lesser Black-backed Gull. It seems too pale to be a first-cycle Herring Gull, and seems to lack the black-n-white checkering typical of Greater Black-backed Gulls. Any thoughts? Opinions?

    Iceland or Glaucous Gull? - Wayne Co., MI USA

    Hi all, I digiscoped this fella amongst Ring-billed Gulls at a nearby pond and was wondering if you had any thoughts about whether its an Iceland or Glaucous Gull. The white wingtips suggest pale Iceland or Glaucous, but I'm not sure about wing projection or bill size to distinguish the two...
