I really miss the UO Circle-T volcano top Orthoscopic eyepieces. They gave arguably the sharpest and highest contrast views in my TV76 of the moon, Jupiter, Mars and Saturn that I’ve ever seen. I see many unbranded copies on the internet but I am hesitant to purchase them. I owned the 12.5mm and the 9mm UO Orthos and sold them to help fund the 13 Ethos years ago. I could kick myself for letting them go!

I agree they were excellent for contrast.  All's not lost however as they can sometimes be found used in the classifieds.

Yes, every so often you’ll see one pop up for a hefty price...but rightfully so. They really were incredible eyepieces.

Never disappointed: I had these out about a week ago with a Vixen SD81S... still sweet after all these years.

 I have a from Japan 9mm Astro Hutech  that's very high quality both optically and build wise.  There's a good range of FLs. David

Unless you have your heart set on volcano-tops, these are also quite good:

Also available individually at Agena for $100, roughly the same as the UOs when they were discontinued.

It might be worth pointing out that Astronomics is getting in some Orthoscopics which Takahashi seems to think are good enough to have the Takahashi name?  https://www.astronom...71639b-85031397

 

I don't know if they are as good as the University Optics but for all I know they could actually be better.

The Takahashi orthos are available. I have pairs of 32, 25, and 18mm. Below that eye relief isn’t optimal. That’s why I sold the UO 6mm I had.

Yes Craig, I’ve heard good things about the KK Orthos.

Wow! Thanks OleCuss. I didn’t know about these but do now! Price is fantastic too for an ortho. Might be worth trying out the 12.5 and seeing how the view is.

I have the 6mm KK Fujiyama Ortho and I love it. The eye relief is OK for me (but I like tight eye relief) and the clarity and contrast are excellent in my opinion.

And, the Fujiyamas are parfocal, or very nearly so, which can't be said for the UOs. When used in a turret, the KKs are very handy in this respect.

I think Craig and I are twins separated at birth........ I have the 4, 6, 9, 12.5 and 18 in the 4-hole turret and swap the 18 and 4 depending on whatever scope I choose to use.

I had some UO's that were replaced with KK Fujiyama's that are now replaced with Tak Abbe Orthos that I think are the best of the lot.

No other current market or historical Ortho interests me. The TAO's are the end of the game for me. They're good.

+1 regarding Takahasho Orthos. They work great on DSO's as well. They're my go to eyepieces.

Although I have a couple of UO pairs, I greatly prefer the square top type. These can mount batwing eye guards which help when binoviewing.

 

Enough eye relief is important to me so I don't really use ortho's that are shorter than 10mm. I'd rather do the walk of shame with a Barlow. :D

The UO volcano tops are good eyepieces, I’ve had a couple. Don’t kick yourself for letting them go. I did the same thing and haven’t looked back since the Tak Abbe Orthos came out. In the 3 or 4 years I’ve had my ZAO II’s I haven’t had one night where I’ve seen them out perform the Tak Abbes on deep sky. Though my 4mm Tak Abbe was a flawed eyepiece I got rid of. I have 50 or so eyepieces, and the Tak Abbes are the best price to performance eyepieces I own.

 

I’m sure no one needs to buy the $50 Starbase branded Tak eyepieces to discover what they are getting.

Allan, the $50 Starbase Taks are not good?

I wouldn't say they are not good, just that when spending $50 on an eyepiece you need to have your level of expectation set first. $50 is not a lot of money for a manufacturer to sell an eyepiece, so there will be cuts in material quality and workmanship that goes into making it.
