Opticron Discovery WP PC 8x50 Binoculars, Black

Product Information

Thats what I use. Absolutely no complaints. Took off a Docter 3-12 * 56 to put Swarovski on, and can honestly say I prefer the fixed mag. The Docter obviously had better light gathering ability but I dont miss the variable mag as much as I thought I would. Not many of us have used or even seen them but two that have are Hermann (post #4 above) and Altavista, who commented on it here: https://www.birdforum.net/showpost.php?p=4032574&postcount=54 There is also a certain sense of history there. The Leica Trinovid largely first defined what continues today as the modern roof prism binocular, with internal focusing, full waterproofing, adjustable mechanical eyecups, and left/right eye adjustment integral with the focusing mechanism. It was also one of the first with prism phase correction coating, but sadly, Zeiss set that precedent a couple of years previous, you can't win em all I guess! I hope you enjoy yours.

The name Trinovid was first used in 1958 with the first series of the Trinovid range. This is today a rare and expensive beast as only a few hundred were built (attached is a picture of the 8x40). The name came from : FMC Broadband Coating Technology ] The lightweight cruise binoculars is cover with BAK4 prism texture. The objective lens use optical FMC multilayer broadband green film, and the eyepiece-optical is made of blue FMC coating. All design can can mostly reflect the light to keep a good image and make you have a amazing experience. A 25mm Plossl gives 6.1 deg. I don't know of anything that needs 8 deg. 52 deg is not an expansive afov, but is sharp, and long eye relief for winter eye fog. Also my amici prism 20mm clear aperture may be an issue. A bright 6.25mm exit pupil will be nice. I have been against ten power binoculars since I first started birding, but the 32mm Ultravids are very easy to hold steady, even though, when I first tested them, they seemed too small for my hands. But birding in Arizona especially convinced me that I needed more power; there were too many times when I wished I could see just a little more detail to positively ID a bird (and the wide open spaces in the desert allow for much more long distance birding than here in Michigan). My 8x42 Trinovids were my main binoculars for many years, but on some days they are actually too bright - watching hawk migrations on clear days would give me a headache. But most Dobs as well as a variety of other scopes have their finder mounted at an angle. This means the finder crosshairs are not aligned with the chart cross hairs and it's more difficult to navigate the night sky. When they are aligned, it makes precise pointing much easier because I can align the cross hairs with stars I have identified on the chart and bingo, the object is centered in the FOV of the main scope.I have my finder fov set in SS5 and I recall that I couldn't quite get the edge fov stars in my finder to match up to what SS5 was showing me. So yeah, seems 5.4 degrees would be more accurate. Is it smooth or rough to turn? I've read some comments that Leica improved the focus on the HDs and that they are easier to turn than the BRs, but then a HD user with a stiff focuser posted a comment that seemed to contradict that, so I'm not sure what to believe about the HD's focuser. Smoother than the BR's or not? Not sure if this is the right place to ask, but what is the real Field of View of an 8x50 finder. The one I am referring to comes with the Skywatcher Dobs. Although way outside the birding mainstream, the 8x56 Zeiss FL has been extensively discussed here. It is apparently so good that it is regarded as almost an optical curiosity, and stands on a unique view-quality pedestal. 44 ounces of pure joy, they say. You might want to consider it too, especially if you plan to put it to its intended usage, low light.

An 8 degree FOV would make star hopping a snap. At 5.5 degrees, I often need to make leaps of faith to get to the next star. Thanks to these features, Ultravid binoculars are ideal companions even on challenging tours. There are very few manufacturers who offer such a sophisticated and wide product range of premium binoculars. All models combine precise and robust mechanisms, high transmission, maximum stray-light suppression and brilliant contrast for perfect image sharpness – no matter which front lens diameter and magnification factor you use. Whether as a small companion on day trips, or as a leading light for observation at night - the Ultravid HD-Plus binoculars are the ideal all-rounders for the perfect viewing experience. I would not hesitate to go for the 8x50 BA. Although a bit dimmer (about 6%) than Ultravid due to its silver rather than dielectric prism coatings, in low light the large exit pupil will supercede the few percent transmission difference. If it's dark enough that your pupils open even as far as 5.5mm, it should surpass in brightness any 8x42 made. Also, something that is increasingly important to me, in bright daylight the reduced pupil of the eye will effectively stop the 8x50 down from its native focal ratio of about f/4 to about f/12, which reduces all aberrations by more than the same effect does in smaller exit-pupil binoculars. This effect has been remarked on by Henry Link regarding his 8x56 Zeiss FL, and I believe it is responsible for much of the high performance of my 7x50 Fujinon FMT-SX porro. Most finders have 40 deg kelner eyepieces. That keeps the edge stars and cross hairs sharp. I wish they would use a Plossl at least. And who needs cross hairs? I know where the center is. A finder could find much better if it were 60 degrees, I think. Likely it is a trade off with eye relief and weight. I'm probably one of the few who uses the 8x56 FL for birding. It's just too large and heavy to attract much interest from birders. I wrote about it here last spring:Whether you are a casual observer or a dedicated hobbyist, everyone benefits from having a pair of top-quality binoculars. These compact devices bring distant objects into focus clearly and allow even novice naturalists to see details they might not have noticed.

The Ultima DX series combines excellent optics, high-quality construction, and affordability. It is ideal for serious bird watchers who need a lightweight, easy-to-use binocular, as well as outdoor enthusiasts who value rugged durability and resistance.

It seems to me, my GSO RACI finder is about 5 degrees. Agena specs it a 5.4 degrees. Find beautiful home design ideas & useful how-tos to create your dream home.

Not quite as heavy as 8x56's, but with a large enough exit pupil for use in low light. Still too large and too heavy for everyday use though.

I'm guessing the prisms they use to erect the image are also too small to support a wider field of view. I have a S&B 8 x 56 and a Swarovski 8 x 50 . If i had to buy again i would have two swarovski 8 x 50's. After nearly 100 hours of research, we were able to come up with many top products from prominent brands.

I'm now on the hunt for a fixed power scope and had a play with a Swaro Habicht 8x50 fixed power scope (Reticule 4A) yesterday and was very impressed. THANKS. I never though of using a digital level to measure. I am guessing mine is the GSO version, but that simply is a guess.Hopefully the skies around here will cooperate this weekend and I will give it a shot to see what I get.
