every reviewer has said the BCOs use newer, superior coatings than the original BGOs.

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?


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.

Now, I realize they're not made in Japan, but a lot of excellent TeleVue product is coming out of Taiwan these days.

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

I thought BCO was from mainland China?

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. :thinking:
