    Empid on Mount Diablo, CA USA

    Even with that yellow wash on the belly, hunched posture, wing bars, eye ring, and orangish bill?

    Empid on Mount Diablo, CA USA

    Anyone got a good answer on this Empidonax flycatcher? I have talked myself in and out of Gray, Dusky, Hammonds, and Wetsern Wood-Pewee.

    Mallard (I think)? American Black Duck? Hybrid?

    I wish! It was tucked the entire time I was around. Thanks for the replies everyone, I had not considered an intersex mallard even though I was vaguely aware of this phenomenon. Certainly interesting things to think about!

    Mallard (I think)? American Black Duck? Hybrid?

    I was going through photos from a month or so back when I remembered taking a photo of a weird duck which I assumed was a mallard with it's head feathers coming in due to my location (Oakland, CA, USA) but I am now having a sliver of doubt on the ID based on a few things: The sharpness of the...

    SVBONY SA205 vs. Nikon Monarch 7 About the same in: Glare suppression Size and weight Eye relief Focus action Monarch 7: Noticeably wider FOV Better contrast and coatings Slightly less CA Feels a little more robust More comfortable to hold SA205: More forgiving eye placement Slightly better...

    SVBONY SA205 Review

    SVBONY SA205 vs. Athlon Ares 8x36 Despite having 42mm of aperture, the SA205 is shorter and almost as light. SA205 has a smoother more precise focuser. Despite both claiming a 7.7 degree FOV, the Ares has a noticeably wider AFOV than the SA205. The Ares also seems to have more magnification...

    SVBONY SA205 Review

    SVBONY is a relative new-comer to the sport optics game having built up their reputation as a direct-to-consumer Chinese telescope gear company. Their SV202 model has been rather polarizing here boasting ED glass and dielectric prisms at a price far below what one would pay for these features. I...

    SVBONY SV202, a Bad Sample?

    I had an interesting revelation today with regards to the ring of light. The TMB eyepiece I could very clearly see what you were describing in doesn’t always show it. It shows it in my celestron hunmingbird and celestron c90 mask cass however today when I put it in my Orion grand view ED 65mm it...

    New 100 ED spotting scope

    I had the SVBONY SA405 (80mm) which seems to share some genes with this class of china scopes. My impression was not at all positive. The interchange 1.25” eyepiece was stuck out of the box and the molded armor wasn’t quite straight. Optics were also pretty poor, image barely held up to 40x. A...

    Vixen @Six 6x18: quirky and surprising pocket binocular

    After reading your post I knew I had to try them! They arrived last night and having had the chance to try them out under the night sky and today in the sunlight I have to say I am quite impressed! They are incredibly lightweight and compact, give an overall pleasing image, and very fun. I agree...

    Seeking advice on tripod for Kowa TSN99-A

    If price is really not a concern then I would go with the Gitzo GT5533LS. It’s super stable while not outrageously heavy so carrying up to a km should be doable. More info on some good tripod testing can be found here.

    Ultralight tripod/head for a 400 g (14 oz) scope

    I have a monopod I’ve used with my Celestron hummingbird and I find I max out of tolerable viewing around 30x and it takes some getting used to how to hold it. It has a rubber spike which pulls off to reveal a metal spike and I find it most stable with the metal spike in soft ground like grass...

    Seeking advice on tripod for Kowa TSN99-A

    How far do you need to carry it to your viewing locations? Weight and leg diameter are the two things I have found most helpful for stability in wind but are also the two things that make tripods less portable.

    No. You may be able to get $20.

    Poll: will you buy Swarovski AX Visio?

    I like the idea and would buy one but not anywhere near that price. Give me $500 binoculars with a $500 bridge camera and the same mobile connective abilities for $1000 and then I would be interested for travel where I might not know what I am looking at immediately.

    Bay Area/Sac - Northern CA Dealer Suggestions

    My experiences at all 3 of those stores have been pretty good. They will have the full vortex lineup, full Leupold lineup, some Swaro and Zeiss, some bushnell, some athlon, and occasionally some celestron/meopta/sig sauer.

    Bay Area/Sac - Northern CA Dealer Suggestions

    There’s a bass pro shop in Roseville with an optics counter and a huge Cabela’s with an optics counter just west of Reno. The sportsman’s warehouse in Fairfield also has an optics counter.

    What determines the field of view for the same magnification and objective lens?

    Yes I was just being lazy/careless when I said diameter. You could replace r with d/2 but it is easier to write as r (and diameter is the convention when talking about field stop width).

    What determines the field of view for the same magnification and objective lens?
