I am sorry to report, NO, and I am close to give up at this point, they do not come out with info, they always delay me again and again.

I started to work with Valery Deryuzhin of Aries on a new eyepiece project, he made the AP SPL series as you may know.

I am shure it will be a longer way till we see some

For now I am thinking to order at my own risk some small , expensive runs of Super Monos and sell them singles at the needet high price.

It looks to me some of the best players in the market have to much business, otherwise they would not be so slow

Hi Markus
Please don't give up on the new long focal length Orthos.
I'd realy like a pair of 30-something mm focal length orthos for Solar bino viewing.
Best Regards
Carl

OK, Markus I will take the bait

What is your new project with Aries?

Regarding the Supermonos, I'm still interested in a pair of 21mm Monos.

the german company talked yesterday with me, they did not give up, but the Docter Ing who doing the design, wants to do something special and have to check all international patents, that why it takes them so long

we also came up with the Idea to re-introduce the famous 25 mm aspherical Zeiss again , same Body style, interested ?

Markus, I would be interested in the 25mm Aspheric. I sold my pair earlier and regret it!

OK, will wait to see if the designer makes something very spezial.

Would the 25mm Aspheric work down to f/4.5?

I've been happy with it down to f/6 in a Newt but others with different levels of focus accommodation will feel differently. Most times I used it in a f/9 refractor and it was excellent to my eyes.

F/4.5 is even hard for eyepieces like Nagler or Ethos, the 25 will be not good at the edge, so I say no

I think the lesson you can draw from this thread is "If you find someone to make it, it will sell".

The problem here is words like "short run", "expensive". I think this kind of eyepieces should be available more comercially, since I think they will sell quite well.

That is good.

Markus, what do you mean re-introduce? Don't you still sell the 25mm aspherics on your website?

I think I would prefer 20mm to complement the ZAO-II 16s and the aspheric triplets.

As much as I like the 25mm aspheric triplets (I have 4 of them!), they do not have the edge correction (unbarlowed) of the ZAO-II 16. So an equivalent of the ZAO-II on 20, 25 or 32mm would be welcome. Below that there are already ZAO-IIs and Monocentrics.

years ago we bought from Zeiss the aspherics orthos, Berliner Glas took out the glas and installed it into a eyepiece mechanics matched in apperane to the monos.
This Job can be done again.

Regards a new better corrected design, I can say again, we must wait till the optical engineers come out with here result.

We still have some hope :-)

I think the ZAO I 25mm and 34mm were amazing eyepieces.
If you can make more, they will sell!

why not starting a remake of something like the atrophyics super planetary eyepieces, a three lense design, they have excellent performance and much larger eyerelief than plössls and orthos

I always asked, why not a remake of the great ZAO-II's (1:1 on par with Zeiss quality)? Acceptable eye relief in a 4 element 2 groups design, and 43° field of view.

But you are right: Why not a remake of AP SPL's? The SPL's also deliver 43° field of view. But at increased, quite generous eye relief, which varies from 125% (4mm) to 140% (8-12mm) of the focal length.

BTW, the SPL optical components were manufactured under the management of Valery Deryuzhin by Aries in the Ukraine, an old business partner of Markus Ludes / APM Telescopes...

Interesting question. Do you simply reintroduce a know design or do you try to introduce something new? Personally I'm waiting to see if the designer at Berliner Glas(?) has a truly new idea...I like to try new things
