Takahashi Japan (Google Translate > English) still states for the Abbe 6mm, 12.5mm and 25mm "coming soon" (scroll down to the end).

Thanks for the link Stephan

I just hope it won't take as long as the BCOs did.

Me either.

And just by the way, I received the 9mm yesterday from Tak America. Same quality of build as the 32mm, dark coatings, etc. I'll be anxious to see how it performs against my BGO, 8mm Brandon, and 10mm Zeiss Jena. Looks to be clear tomorrow night.

Hi Rodger,

Thanks for the report. Did you find the 28mm eye relief excessive? How much is taken up by the recessed eyelens?

Thanks,

The 32 mm does have a lot of eye relief, but I didn't find it too hard to keep my head still. The eye cup wasn't much help though.

So I took the 18mm and 9mm Tak orthos out Friday night with my EON 120 mm and compared them to some fairly popular eyepieces. Here's what I saw:

For the Tak 18mm, the build quality and coatings are top notch. For scatter, I used Sirius, and the Tak, Brandon 16 mm, and the BGO 18 mm were all about the same. The 16 mm Zeiss Jena showed a little less. These results are similar to the 32 mm Tak I talked about earlier. From a planetary detail perspective, I used Jupiter, they were pretty much all equal. The belts on Jupiter were sharp, well defined, and I could see a lot of detail in them with varying hues of brown. It was easy to see the "Great Red Spot". For sharpness across the field of view I used M41. The 18 mm Tak had no trouble at all with sharpness to the edge of the field. Ergonomically the 18 mm Tak was very easy to use. With my eye gently touching the rubber eye cup the field was fully illuminated.

Now onto the 9 mm Tak. The same high quality coatings and build quality mentioned earlier. Ergonomically, I had to kind of push my eye against the rubber eye cup to see a fully illuminated field. Not quite as good as the 18 mm. From a scatter perspective I was surprised to find that the Tak 9 mm had the least scatter of a BGO 9 mm, a Brandon 8 mm, and Zeiss Jena 10 mm. Detail on Jupiter was fantastic in the Tak 9 mm, Brandon, and the BGO. The red spot was easy and there was a wealth of detail in the belts. Similar to what I described for 18 mm. It was just bigger, but awesomely sharp. Surprisingly, Zeiss Jena didn't do as well. It definately struggled in this area. The Tak 9mm was also sharp to the edge of the field while veiwing M41.

Overall I would say the Taks are at least the equivalent of the BGOs and very close to the Brandons and Zeiss Jenas. At times being their equal. I intend to put together a binoviewing set, which I was going to do with the BGOs until production was stopped.

I'll be anxious to hear what other folks have to say about these eyepieces.

Thanks for the observation report Would be interesting to see a shootout of the new Tak 9mm vs the 9mm Pentax SMC Ortho.

Sounds like something you should do BillP. I don't have a Pentax SMC Ortho.

Did you find the 32mm comfortable to use? I purchased a 25mm circle T ortho once thinking it would be similar to the shorter focal lengths as far as comfort goes; BUT, I quickly found it very difficult to use as far as eye placement goes. It was very prone to "blackout" if the eye was not placed in exactly the right position. I can't tolerate eyepieces with this characteristic while standing on a ladder looking thru a long focal length Dob. The seller was gracious enough to allow me to return the EP as it was unusable AFAIAC.

You do have to hover above the 32 mm eyepiece because your eye doesn't touch the eye cup. But as you found, that's true of other eyepieces as well. The 32 mm Brandon and most 25 mm Orthos come to mind. I didn't find it to be a problem, but I wasn't standing on a ladder looking through a long focal length Dob. If I were you I would borrow one first before buying. I wanted the 32 mm to fill out my Ortho collection. No one to my knowledge has made that long of a focal length Ortho in quite awhile.

For what it's worth, I compared the 32 mm Brandon (50th anni version) and the 32 mm Tak Abbe in a Tak FS-60Q (real quick, though).
The eye placement with the Tak was very easy, while I had more difficulties with my Brandon.

I came home from work last night and my new TAK 18mm ortho was dropped of by the ups man, I had some running to do and every time I walked out of a store I looked up at a nice clear sky. I made the mistake of thinking about setting up the scope on my GM-8 and comparing it with some others in the eyepiece case. I say mistake because when I pulled in the drive the sky had socked in with a nice low grey cloud cover. Happy Thankgiving.

Hi to all yesterday i've received all the focals (Except the 25mm). Now, in Italy is raining. I hope to test its the next week. You can see some photos, here: http://www.astrotest.it/preview-fotografica-oculari-takahashi-ortho-abbe/ with comparison of other Eyepieces. Best Regards from Italy
