    Tripod/head combo for Swaro ATS 65

    Congratulations with that. The differences may not be as dramatic as you imagined, but you might notice a subtle accumulation of improved qualities... sharper field, greater contrast, less CA.. I'm looking forward to hearing about it. I'll be testing the FLM tripod some more this weekend with...

    Tripod/head combo for Swaro ATS 65

    Corroboration? https://www.birdforum.net/showpost.php?p=3786570&postcount=23 referencing a Meopta 82 S2 with a 20-70 zoom... "...and it darkens when I zoom between 50-70x."

    Tripod/head combo for Swaro ATS 65

    Its possible that the physics of optics are not in our favour, or at least wholly corresponding to our interests. By that I mean the exit pupil calculation is likely playing a big role in our perception of brightness. In daylight, when I go above 35x on my scope, I can literally see it getting...

    Tripod/head combo for Swaro ATS 65

    Hi Yarelli, I've gone out birding with the scope 4 times, and carried it a few miles each time. It has not been in any kind of a breeze, so in some respects just not put to the test. I'm fine with the weight. I like the head... size, smoothness of motion. There's a few quirks about where...

    Tripod/head combo for Swaro ATS 65

    What tripod were you using? I just got a Sirui VA-5, and my scope (Televid 65) is coming on Monday. I have yet to field test this setup with a 1541 Gitzo that I already own. I'm beginning to suspect that anything other than no breeze might be a problem, but we'll see. I did also order a longer...
