University Optics Orthoscopic 9mm
This is one of the recent "T" multi-coated models and has very good image quality in terms of sharpness, contrast, brightness, lack of ghosting, and color purity. Fairly narrow FOV, but consistent with other Abbe Orthos of this focal length. The image quality and eye relief are not quite as good, though, as in the 9mm Pentax SMC Ortho. However, it is a very good value for the price.

I've compared quite a few eyepieces in f/5.4 and f/5.3 refractors, and am basing my ratings on image quality, not FOV.

Rare value for planetary, lunar and binary star observing. I use this eyepiece with a C9.25. Excellent contrast, sharpness, overall image quality. Barlows well with Ultima barlow on good nights with tight, clean Airy disks. FOV not as wide as my TV plossls, panoptics, or ultimas, but definitely sharper. Eye relief is not as bad as some would have you believe. I intend to try the 12.5 and 7, who knows, I wouldn't mind acquiring the whole line of Abbe Orthos from UO.

Exceptional eyepiece for lunar, planetary and globulars - some of the sharpest and brightest views I have ever had, bar none. Barlows very well with the Celestron Ultima 2x barlow for excellent high power planetary observations. Eye relief is long enough that I can see 95% of the FOV with my glasses on.

I have tried numerous mid- to high-end 5mm eyepieces to get the magnification I need for the planets and a wider FOV. None compare with the U.O. 9mm barlowed for sharpness and contrast.

Get one, keep it and love it.

I recently purchased a used 9mm UO Ortho and it is definitely a keeper! I used it in my 13.1" f/4.5 Coulter, 8" SCT, and my son's 10" f/4.5 Dob and it performed well in all three. The views of Saturn were most spectacular. I was able to discern details in the ring bands and shadows on the surface clearer that with my 7mm Nagler. I have seen lots of comments stating the eyerelief was unbearable but it did not bother me whatsoever...I don't wear glasses. I can't wait to get a night when the atmosphere is extremely stead so I can try barlowing for higher magnifications.

Excellet ep! Very sharp. Very contrasty. Provides 135x in my 8" f/6. Jupiter looked great. Nice bright flat field views right to the edge of field. At 270x w/TV 2x barlow, Saturn was awesome. Can't wait to try this out on Mars. I am a non eyeglass wearer and I would say the eye relief is comfortable.
Also this is my first ortho and the fov is not as bad as I thought it would be.Thanks,
Jason

What a great eyepiece. M13 was best I've seen it. Saturn and Jupiter were great barlowed. Eye relief was pleasent. Comparing this to my TV plossls I would have to give the edge in brightness to the ortho, fov to the plossl although not a great deal and the quality of view about the same. The ortho beats it hands down in price.

Using it on the Celestron SCT 9.25" F/10 (261X), the 9mm give excellent views of Saturn and Jupiter with no ghosting (I did line the barrel with protostar flock paper). These orthos are every bit as good as everyone says, with an incredible price to boot! The only problem is the narrow FOV. I don't mind the small eye relief, however. Now that I'm using a Starmaster 12.5" F/4.5, I'm sorry to say but I've decided to sell the 9mm (hand-tracking it is a bitch on the SM with the narrow FOV). I give it a 9 - no EP deserves a 10; they can all be improved upon.

I bought one of these for the 2003 Mars opposition. Very fine ep. Excellent optics, great planetary eyepiece. Wound up selling it, but I'd buy one again.

I know it's all been said, but here's my two cents anyway:
If you can get passed the narrow FOV, you'll realise you're holding a top notch eyepiece. Mine is the latest version, an ortho HD. It's supposed to have better lens coating than the Abbe orthos (i.e. the volcano top model) and grooved barrel.
I don't have the resources ($$) to compare it with Pentax' and Zeiss' orthos, but for something this good to be sold at less than 75$ (the ''other guys'' orthos go for 3 to 8 times that price!), it's normal to think there's a catch. The only one I know is that you won't find any large page-size ads in top astronomy magazines for this one. U.O. keep their costs down to a minimum (i.e. no publicity); those savings are then passed on to us, the customers!
Spread the word!

Evaluation was done using a 114mm f7.9 Newton, a 200mm f6.0 Dob and a Celestron C80 ED on occasion.
