hey SMARK, I'm not familiar with what you call the 'archives'.

 

do you mean just past articles in general? under the mini-review thread, there are two entries for the Nobilem's, no Aspectem's.

 

thanks for the clarification and hand holding.  :rolleyes:

 

Yeah. I'll try to post a few here...

A forum member (andresin) owns the docters and the fujinon 40x150 ed and he rated both on the same level, exit pupil aside.

I remember stumbling across a hunting site that compared the Aspectum UWA to the Kowa Highlanders. I recall the Highlander won by a hair.

makes sense! the Kowa's do have a 2mm aperture advantage!  ;)

Depends which Aspectem I guess....

There are 3 versions. The ones with the fixed Docter 12.5 eyepieces on it (40x) get very good ratings. This one has the widest FOV. Stars sharp till the edge...

 

Didn't buy it as it is a "straight" binocular.

I had an opportunity yesterday at Astrofest in London to spend time with the Kowa Highlander with 32x eyepieces.

 

The Iowa rep agreed to set them up outside the venue so we could look at a distant gilded figure on top of a building. Against the grey sky the pointed star the statue was holding aloft looked really sharp. No sign at all of any chromatic aberration and I mean nothing. The colour saturation and sharpness of the image were outstanding. The last time I had a terrestrial view through a binocular this engaging was with the 40x80 Docter.

 

The whole instrument is so compact and easy to carry around it feels like a smaller instrument. I discussed cases with the Kowa rep who suggested that rather than forking out £400 ($600 approx) for the Kowa aluminium case that a pelican case or rucksack were the most used in his experience. The extra eyepiece sets were scarily expensive. However I think the 32x with its generous 70° field and 20mm eye relief hits the sweet spot.

 

As you can probably gather I was really impressed by this instrument and with the price reduction can see one of these in my future. I think I would want to keep the APM 100mm APO binocular with its higher power capability but the Kowa would make an incredible take anywhere package.

Well, you can really say anything bad of the kowa while look at the sky, since it was designed for terrestrial use.

Kowa just dont made astro stuff. Period

I am under the impression that the angled binos descended from antiaircraft glasses.

I have never heard anyone criticize the Kowa for astronomical use- quite the opposite.

I also was at astrofest in London yesterday and was part of the group (which grew steadily larger over time!) that looked at the gilded statue - I was so impressed I bought one on the spot. Looking forward to trying it out - it was good to be able to look at both the kowa and the apm 100ed at astrofest. It certainly showed me how much more portable the kowa is than the apm, I've found the kowa works well on the technosky Elle mount I already have.

Am also considering getting the 50x eyepieces but the cost!! I would be interested to hear any owners opinions on whether getting the 50x would be worthwhile for the moon and planets?

If you wait a month I can tell you :-)

I was so impressed by  the Kowa's performance on Jupiter, I decided to get the 50x instead of pushing my APM's beyond the 44x my Docters give. I still needed to buy an 8-9mm pair, so instead of doing that for the APM I will go for the Kowa.

 

The reason I bought the Kowa was size and weight. The center FOV performance is very good. Very sharp and no CA from what I saw....

 

I ordered a Pelican 1520. Seems stronger than the Kowa case.

 

The Kowa isn't perfect, nothing is. All in life is a trade off. It is very useful for astronomy ! You can see I have quite some equipment. The Kowa (like the APM with the 12.5 Docter) really surprised me....

 

I am happy to have a "perfect" travel BT....

I have a pair of 7mm Naglers that are cut down to work in the Kowa's (64x). 

 

They do give a great view of Jupiter and Saturn, but I feel that somewhere between 40-50x would be the sweet spot.

 

I'm looking into trying the 10mm Delos next.

I wonder how cut down Doctors would perform in the Kowa.

This combination could be a winner with no other eyepieces er evneeded.

Perhaps a perfect substitution for the 45° Aspectem everyone is lurking for...

Gavin,

 

As a happy Kowa Highlander Fluorite owner since more than 3 years, I highly recommend Kowa's 50x eyepieces. I would them buy again at any time.

They show you what the 32x e.p.'s can't. In particular on the moon, planets, but also on dense open clusters, the 50x simply are a must have.
But Kowa's 50x e.p.'s also excel on unequal double stars with very faint companions. Example: used under mediocre suburban  4.9 skies, Kowa's 50x e.p.'s permit me to safely split Sirius A/B (the "Pup"). This is quite impressive and proof of the very high contrast Fluorite main optics with excellent stray light control.

 

 

Stephan

I need my Docters for my APM :-)

 

I saw via Amazon you can buy the 50x in Japan for much less.....

Beside the Kowa and the APM there is also another very interesting option:

95mm aperture, small and lightweight, very good objectives, takes standard 2" and 1,25" eyepieces.

Hi Graham,

 

like with every EMS binoscoope, you do have two adjustment screws for both axes, so the binos are always in perfect collimation.

Jochen, where would one buy that Swaro-binoscope now, if they had the money?  :question:

 

and I'm curious to know more about the Kowa's and use of third party eyepieces. I remember reading more about this about 5 or so years ago, people testing a number of Televue eypeices.

 

perhaps we need to find a rich benefactor who can buy two of each one and test them out for us!  :lol:

 

and now that there are so many Televue clones out there with 99% the performance (Explore and Vixen for instance), perhaps it will be a 'cheaper' endevour than before. :rolleyes: 

 

edit - SMark, do you know what eyepieces Sieberts is selling for the Highlander? $260 isn't cheap, but I'd hate to consider buying eyepieces that would introduce CA because they're not up to spec compared to the Kowa eyepieces.

 

and I guess I should ask if there is any information on what is needed for 'cutting' on the Televue ep's so they fit and work with the Highlanders.
