Had a 6mm Kasai, green box stamped japan, nothing on the eyepiece itself. Did you ever, EVER, even see a lens from japan not marked. But the chinas do it all the time, guess they they are ashamed or deliberate deception?

Hey, maybe the box was made in Japan.

I do know there are knockoffs as well as just mfg mistakes. Take the UO OPS line, this was an attempt by UO to incorporate planetary filtering into the glass lenses themselves instead of screw-on filters. When the idea didn't go over that well (they're still great on planets, just not on anything else, but hey, that's why they were call planetaries by UO)some of the leftover housings were used for regular ortho lenses. You can tell a true OPS because it has a mirrored surface look to it. Another example is the Lumnicon filters, some recently have came out with no markings on the filters.

Yep...have one of those. Looks as if someone simply took a black Sharpie and marked out the "OPS" on the lens housing.

Why would they be ashamed?
Plenty of good optics from China, including Tele Vue.

And then there are performance issues. All these 6mm lenses were exactly the same in the Carton 100/1300 and the 10" dob.

Except the one with the gold ring was slightly sharper/crisper/contrasty than the others, Omegon Super Plossl, bought on ebay, shipped from Germany, with no makers mark either.

They had an incident a while back with a whole bunch of mislabelled filters, so I'm not too surprised if they opted to avoid labelling altogether :-)

I've been testing a set of the Astro Hutech orthos - 5, 6, 7, 9, 12.5 and 18mm. All have "Japan" printed on their bodies, underneath the Astro Hutech branding. The 5, 7, 9 and 12.5 Hutech's are identical to the Baader GO's in all respects including coating hue and, most importantly, performance. The 6mm and 18mm Hutech's have shorter bodies than the Baader equivalents and reach focus around 8mm further outwards. Otherwise their performance appears to match the Baader GO equivalents as well.

In the UK the Hutech's are priced around $20 more than the Baader GO's were.

Hope the new UO orthos are from Japan, not that China can't make a quality ep, just look at Explore Scientific. But I want the same product everyone has raved about over the years, the one that gave the UO HD orthos a good reputation to begin with, not a "look a like", such as the Baader Classic Orthos compared to the NGOs.

Jan at UO has specifically said that the coming HD orthos are completely Japanese made, from the lenses to the machining to the coatings.

Thanks John, for the "on the ground" assessment. The Hutechs have a good pedigree and I'm pleased they seem to meet expectations. I imagine the much anticipated UOs will do the same.

I would guess if people dont start buying them off the shelves the current stock might be the last. For all the hype no one seems to be buying from what I can see. Agena lists numbers in stock and they dont seem to be moving.......




I've got a full set of BGOs so I'm holding out for the promised 4mm and 25mm! Although the report on focus position being further out on the 18mm makes me think about replacing my 18mm pair, hmm..,

I just bought a pair of 9mm Hutechs from Agena. I will be comparing them with my 9mm BGO using the AP 175. When I am done I will post an observing report.

Is there a due date for the new UO HDs?

I'm very very very glad these are coming back. They have a solid place in amateur astronomy.
