New oberwerk toys ultra 15x70
      #1000900 - 06/15/06 05:07 PM Attachment (325 downloads)

i bought the bt-80-45 the bt-100-45 and the new ultra 15x70s,must say dealing with kevin at oberwerk is a joy and you can't beat the shipping cost 5.00 per bino. there have been reviews on the 2 large binoculars in cloudy nights and i concur with the great reviews,super sharp optics.as for the ultra's they are a very good binocular for 350.00,built solid and no worry about going out of collimation.very sharp optics and contrast. sharp out to about 85% of the field,bright as the fujinons,but the fujinons have the better edge sharpness,eye relief is a little short if you have to wear eyeglasses.little on the heavy side,they are the closest thing to the fujinons so far coming out of china and at about half the price,i can't praise kevin at oberwerk enough for his fine sevice and super fast shipping.

Hey John! I've been checking through here several times a day for the past couple of weeks, anxious to hear obout these new 'Ultra' 15x70s.
I think they are on my short list for acquisition as funds become available.

They sure look small next to those other monsters though.

Niiiiiice. Would love to hear your critique of the 80mm vs. the 100 mm.

John, I am anxious as all get-out to hear about the Ultras - no offense to those two fine BT's you have there.

So, in your opinion, where on the scale of quality would you put the Ultra optics in relation to other large Chinese binos like the Obie 15x70? You say the optics are sharp out to 80%, but I have heard the same thing about the Obie 15x70 "standards" ... is the only difference in the build?

Thanks and clear dark skies.....(Which reminds me.....if ONE new piece of astro gear brings the clouds, then what will THREE bring? Be glad you are in Iowa, or you might have gotten a hurricane!

i have the standard 15x70 also and the ultra's are brighter and have better contrast for night time viewing and a little less color than the fujinons for daytime viewing, don't get me wrong the standard 15x70s are a good binocular for the price.still the older fujinons are the best but the ultras are close.

I like that 'A-Frame' the 15x70s are hanging from too.
Looks like a good bit of it is PVC. Have you posted any thing detailing it?

One other thing the Ultras have over the 'regular' Obies is the waterproofing. I'm guessing they are noticeably more rugged?

BTW, is it just me, or a trick of light, or do the coatings on the Ultra look very purplish compared to the green coatings usually associated with Oberwerk optics? I wonder if the coatings are different that the previous "broadband fully-multicoated" ...?

John - thanks for humoring me. One last question before I end this round of the interrogations!

In respect to flaring and the "pointiness" of stars - how do the Ultras compare to the Obie standard 15x70? Would you say the stars are "sharper" compared to the standard?

Thanks again.....

compared the bt 45-80 to the apogee ra88s,and i must say for a 200.00 or 300.00 more the oberwerks were much brighter better contrast and sharper optics dew to the oversize prisms i think and you can use any eyepiece you want.the 100s are of course brighter

"kevin at oberwerk is a joy"

If you spend enough money with him? I purchased a lowly $149 binocular and had to collimate it myself.

John, I wonder if the 20mm Widescan III's (84deg AFOV) that have a slightly larger fieldstop than the 24mm Panoptics would show any vignetting in the BT45-80 and BT45-100 ? They don't show vignetting in my Denk II unless I use it in .66x Starsweeper (focal reducer) mode.

joe i don't think you would have any vignetting with the 20mm, i use 24mms with a 70 degree field and have no vignetting, the bt80s and the bt100s use very large prisms.you could send them and i can try them out if you like. regards john

I would like to know how the 80mm doublet compares to the 100mm triplet in sharpness? Don't see the OB fork mount that comes with the 100s. Did you not purchase it?

Thanks,
Les

Cota,

Something I've always been curious about... On the BT binoculars, does each objective have its own tube and then the pair of tubes is wrapped in the one piece housing? Or is the housing "open" with both light paths passing through it side-by side? Or maybe there is just partition between the two to prevent the possibility of off-axis light from one side affecting the other.

les both the 80s and 100s are the same sharpness good prisms i think, i would imagine that the color in the triplets would be better but haven't had that much time yet to check them out but they both have super sharp optics. i did have the fork mount and tripod which are good for the price but sent them back for a trade on another binocular, i like my set up better because i can crank the binoculars up and down for different heights with a turn of the handle. regards john

John, I guess if you have no vignetting with 24mm/70 deg AFOV eyepieces then a 20/84 combo should also not have any vignetting. I think I will save up for the BT45-100's since that should bridge the gap between my big binoculars and scopes with the Denk II.
