100mm and Larger Binoculars

One Year Review: Apogee 25 x 100mm Binoculars

Sep 14 2005 06:26 AM | Guest in 100mm and Larger Binoculars

First rule for this beast is, “If you buy them, you must mount them.” I have tried several ways to mount them but I always resort to cheating somewhat. I used the Orion Paragon-Plus binocular mount

Pro-Optic 25x100 Binoculars

Mounted on a fluid head, these “Ultra Giant” binos needs a counterweight when pointed toward zenith. They also need a second arm (not shown) to move effortlessly from target to target, and to take advantage of the smooth movements of the excellent mount.

Oberwerk 25 x 100mm Binoculars

Mar 16 2005 07:30 AM | Mr. Bill in 100mm and Larger Binoculars

I have just returned from 5 days camping in the White Mountains on the California-Nevada border at 8600 feet and in central Nevada at 7600 feet under good to excellent seeing and transparency. I had ample time to evaluate the Oberwerk 25x100 astronomy binoculars (made in China), using them 3-4 hours each night. The following are my impressions on both the viewing and an evaluation of the the optics and mechanics of the binoculars.

Nikon 20 x 120mm Binoculars

Mar 16 2005 07:21 AM | APM M.Ludes in 100mm and Larger Binoculars

Lately I have noticed that a number of binocular observers are asking how the Nikon 20 x 120s perform against other large binoculars , such as Vixen , Myauchi and Fujinon. I have traveled to many dark site star parties in Europe and USA, in which I've had the opportunity to use the Nikons at some length under ideal conditions.

Nikon 20 x 120 III Binoculars

Mar 16 2005 07:15 AM | Guest in 100mm and Larger Binoculars

I've always had an interest in optics, even at an early age. Over the years I've had several different types of high quality, small binoculars that I've used for bird watching; Leica, Ziess, Swarovski and Nikon. I currently use and love my Nikon LX 8x42s. They fit my hands perfectly and the optics are second to none. I've always wanted a large pair of binos that have the quality of Nikons. I'd thought about the 25x150 Fujinons. At one time I had the 10x70 Fujis and was not impressed.

Miyauchi Fluorite 100mm Binoculars

Mar 15 2005 06:49 AM | Dave Novoselsky in 100mm and Larger Binoculars

Having read Mike Barr's comments on SAA regarding his positive experience with his Miyauchi fluorite binoculars, I was intrigued. I already owned several fine, Takahashi refractors, had the AP binoviewer, and was not sure why these (apparently) rather expensive binoculars would provide me with something I already did not have in my existing equipment. This was particularly so since I already had a pair of 16X70 Fujinons. Why pay six times as much for another pair of binoculars? It made no sense to me at the time.

I.T.E. LABT-100 Large Aperture Binocular

Mar 15 2005 06:41 AM | Guest in 100mm and Larger Binoculars

I am a huge fan of viewing the night sky with binoculars, but find that ordinary 50-70mm binoculars don't allow me to see "deep" enough into the night sky, owing to their rather limited aperture and hence light gathering capacity. Larger binoculars, however, are quite expensive and many yield optically unacceptable images (e.g., one such pair of binocs are those marketed by a well known binocular and telescope catalog company...) for premium prices. Nevertheless, the joy of hopping from globular cluster to galaxy cannot be underestimated when behind the helm of a good pair of large binoculars. So when I saw that I.T.E. was offering a modified version of the slowly-becoming-popular 25x/40x-100mm Chinese border patrol binoculars, I decided to give them

Fujinon 150mm Binoculars

Mar 14 2005 01:34 PM | Guest in 100mm and Larger Binoculars

With the discovery of the Hyakutake comet the worlds largest binocular has become known to the general public. Fujinon binoculars have been predominently used in the marine environment and are extremely robust and water resistant. The nitrogen filled interior prevents dew formation of the internal optical surfaces.

When not so young Dave last addressed all of you on the subject of LARGE binoculars, he had fallen in love with a pair of Miyauchi 20X100 Fluorite binoculars. After a promising and exciting honeymoon, we got a divorce. The whole, sad story is on this site as an update to my earlier review of the Miyauchi 100s, see the update at the end. Basically, the first real workout of the Miyauchis under completely dark skies showed a focus/collimation problem. My dealer, Astronomics, took them back. A second set snapped into focus perfectly under dark skies and were as wonderful as my first night with my new bride, er; I mean my new binos. Then I tried looking at the Moon, and saw a yellow/green ring with blue highlights around it. Either poor fluorite or poor lens alignment or who the hell knows. No color in the first set under the same circumstances, so second pair back as well.
