University Optics Orthos new
      #5875449 - 05/21/13 10:24 AM

Does anyone have any experience with the current line of UO Ortho's being sold ?? I have been away for a while and it looks like things have changed with their eyepiece, just wondering if it's the same bang for the buck it was in the past. Would appreciate any info good or bad on any eyepieces they currently sell, Thanks a bunch.

This line is not generally thought of as highly as their previous variety of Orthos in Volcano and HD versions. The Baader Classic Orthos would be a better bet.

I've got an 18 BCO that's mostly used barlowed for lunar-planetary. It has an odd irregularity on about 1/4 of the fieldstop but the optics are very sharp. David

I have the 16.8 & 24mm orthos, no complaints..nice and sharp, & lightweight... they probably wouldn't win any beauty pagents, but simplicity can be nice.

Thanks for the Baader recommendation, after you posted I did some reading about them and they do indeed sound like what I am looking for. Like I said, I have been away from the hobby a while and didn't even know about them so it was a helpful suggestion.

There is also the Hutech orthos from Agena which more closely resemble the old UO HDs.

John,
The Baader Classics Orthos are probably a good bet, but if you feel like waiting a bit, UO has announced that they are bringing back the HD Ortho, which is generally considered to be a step up from the UO volcano-top.

UO HD

If you want the old Japanese volcano tops, however, they crop up frequently on CN and Astromart classifieds, costing about $30-$60 depending on age/condition.

Aren't these the same as HuTech Orthos?

I believe you are right, Gene. On the surface it appears:

University Optics HD = Baader Genuine Orthos = HuTech Orthos

There may be some subtle coating differences, but they seem to all come out of the same Japanese shop.

Jaimo!

Gene,
As far as I can tell, yes. The build, focal lengths, price, and the "coming soon" 25mm in the Hutech line all suggest that these are the same as the new release of the UO HD and that they're built to the same specs (coatings excepted, perhaps) as the earlier HDs and Baader Genuine Orthos.

It will be interesting to see how these come in price wise. Agena is quite a bit cheaper for the Hutechs. I'll get a 9 HC or HD at some point. I had a 18 HC for a while and the image was excellent but it had a weird spot on axis issue when barlowed. Back it went to OPT and I got the 18 BCO. I just took a look through the BCO at a light and the irregular edge wasn't there. Maybe I've got some sort of 18 ortho-barlow curse! David

My 18mm Astro Hutech HCs from Agena appear to be excellent after a couple nights binoviewing with average seeing.

Just did some HA with the 18 BCO. Thought I'd report back on the odd double line look at the very edge of the 18 BCO's FOV when barlowed. Turns out the issue is moot given the ortho vignettes about 2*-3* in my 2X TV barlow and I would expect more in the 3X TV. Image quality is impressive being very sharp. It has lots of but less contrast than my 16 Brandon and is very usable back to back with it like I'm doing now. Got the unused bought used 50th Brandon on Amart for $150. Both eyepieces are money well spent! David

Best,




I agree they are good at least on Saturn so far. The very very far edge of field is a little soft since they expanded from 40-45 degrees to a plossls field of 50 or so but I don't care as I don't observe anything that far off from center.

Yes, and the BCO is brighter on the planets, new HT coatings.


BCOs (6, 10, 18, 32mm) on the Q-Turret

Here's the background about this plossl-size view of the BCO's, like in the 6mm BGO comparison, 40 vs 50-deg or 25% bigger field of view than the older BGO6 sibling or standard orthos. From what I gather, Baader felt that was a good tradeoff (keeping the true Jena Ortho optical design) and increased the field size (50deg) to give users the ability to more easily find objects. Source was surprised the edge performance wasn’t poorer (not worse than a plossl). He remembers when Clave touted their plossl 50deg as a wide field… (he still has a couple of Claves).

These BCO's are modern-day retros in more ways than one.

Best,

Last night the clouds held off long enough to view Saturn! The Moon...not so much. At any rate I was using the 18 BCO and new 16 Brandon back to with a 5X Powermate with my WO ZS-110 with good seeing. I'm finding with orthos one can get quite a bit more power pulling it part way out of a barlow or Powermate than an eyepiece with a built in barlow. What it comes down to is about 215X-245X with the BCO vs 240X-275X with the Brandon. As with the Sun the BCO showed itself to be a worthy partner for the Brandon. Saturn was colorful in both, good detail could be seen on the disk, the moons showed well, and the rings were sharp and 3D. Contrast goes to the Brandon but the BCO has it in abundance. What I like about the combo is the image in the 2 are different with the BCO having a XW like quality vs the Brandons through a glass darkly look. David

How is the in-focus on the BCO+Q-turret? I have the Q-turret too, it's good for comparing several near-FL EP's; unless you can't get them to focus. :-)
