Wait, really? No 18s? Anything between 12 and 20?

I would imagine that the 18mm will also be available.

I'm also interested in the 12.5mm HD Ortho. I sold my BGO 12.5 recently at a price I couldn't refuse. Sometimes I miss it and want another one.

Hmm. UO HDs. Why don't people get the BCOs? They cover a smaller amount of the optical spectrum, admittedly, with only 6, 10, and 18mm offerings, but every reviewer has said the BCOs use newer, superior coatings than the original BGOs. On top of this, they sell for $74 brand spanking new. Now, I realize they're not made in Japan, but a lot of excellent TeleVue product is coming out of Taiwan these days. Now, if you want to pick up the 12, and, if you like scratching your cornea on glass, the 4mm, I can see a reason for someone (read fanatic) picking up those models, but otherwise, what's the big deal? Seems to me the BCOs are already here and shipping and ARE the real deal, and they cost less. So what's the big deal?

Besides, in the 12.5mm size, I'd probably prefer the Sterling Plossl, due to its extra TFOV. The 17mm Sterling Plossl is a great mid-range ocular, and the Sterling 25mm is literally a poor man's Pan 24. Again, what's the big deal? It'll be interesting to see what comes of it, and perhaps Barnett can put together another World Cup of sub 65* performers, but waiting till that time is something I can somehow manage to endure, sans tears.

Actually I've seen a few reviews rating the BCOs as being "so-so". The UO HDs, which I've used, really are great. I haven't seen a so-so UO HD review.

Example: http://stargazerslounge.com/topic/175014-baader-classics-the-story-so-far/

"The view with the BCO seemed as sharp and contrasty as the BGO 6mm but showed just a touch more light scatter / glare from the bright planetary disk. The extra field of view provided by the BCO shows some distortion when objects enter the outer part of the field."

"The field stop of the BCO 6mm was not sharply defined as the razor sharp BGO an Circle-T 6mm orthos, which was slightly annoying but did not seem to affect the optical performance as far as I could see."

It troubles me that the BCO show off axis astigmatism at f/7.5. A standard Abbe Ortho design handles even f/5 pretty well. I ain't sold on the BCOs as a result, and would rather wait for UO HDs, personally.

Regards,

Jim

And you need to ask yourself how would someone writing a review really know this unless they were just repeating some marketing gibberish? The best one could do is say that they measured the transmission and speculate as to why they might be different. It could be true but how would anyone in our position really be able to know that and state it as fact?

+1... or the Hutech/Kasai which I suspect has the same source as the UO HD.

I have the 10 and 6mm BCO for testing purposes. I still haven't taken them out to dark skies yet...to validate them. The BCOs seems good so far

I also got the Barlow...I'm not so confident of it so far. I hope it is just a bad copy.

I used them with my 22" f/4 reflector, Tak TOA150 6" and 4" f/11 achromat in my front yard just looking at stars.

I need more time before I pass judgement on these eyepieces.

Given Kasai are going back into production I wonder why Baader dont reintroduce the BGOs.

I do wonder though if this love affair with orthos will last to keep them in production or whether after the huffing and puffing no one will buy and theybwill once again be taken away. That would be shame I think.

That could well happen. It seems that most amateurs today are more interested in wider and wider fields of view, better corrected edge of field and longer eye relief than a subtley sharper and more contrasty image.

Manish has posted an update on the Hutech/Kasai line. I'm afraid it's more a matter of "no news" rather than "good news". Here's a link:

Well then, there's only one thing to do. Jim Barnett, PJ Anway, and Bill Paolini, as the upholders of genuine Abbe Ortho integrity need to each take 6mm BCO, BGO, a volcano top and perhaps a Brandon for standardization's sake to the skies for a genuine OK Corral shootout. I'm talking no holds barred, all guns blazing. Till the last ep is left standing. Well, at least the last ortho with the Brandon. The Cloudy Nights midnight cowboys are a waiting.

Are the BCOs from that factory? or from Taiwan at all?

I'm in for the full set. Regretted not getting them before they were discontinued. They will compliment my Brandons well. Too bad they didn't go with the volcano top, that would increase sales IMHO. I may have to do a couple doubles for the binoviewer as well.
