Go for the excisting ortho design Marcus. If their going to be anywhere as good as the tmbs where they will sell out regardless of the wide-field large ER everyone want.




Agreed.

How many air-to-glass surfaces in the Konig II?

I applaud your efforts to breathe some new life into a very stagnant simple high end eyepiece market.

Regards,

Jim




From my reading, Konig-I is 1-2-1 design, Konig-II is 2-1-1 and Konig Wide Field is 3-2-1. the Konig-II offers better orthoscopy and ER than the Konig-I. Trying to get more than 55 degrees out of them would mean a sacrifice to orthoscopy, eyerelief, and/or flatness of field.

BGO's are what-95% the performance of ZAO II's?
What could possibly be 95% the performance of an ubered Konig II design? GSO superviews? Naw...oppurtunity is knocking on the Konig II door. More orthos will simply be... more orthos. The best quality sure, but the limited field of view precludes alt/az viewers, and there are more and more of us all the time.

I would be interested in pairs of 20 and 32-34. I will keep the pairs of ZAO-II and aspheric triplets, so not interested in 25 and 16. However 20 fits perfectly between with 1.25x progression.
I am only interested in ZAO-II grade or better. Not interested in BGO grade or even SuperBGO grade. I compared BGO 18 to ZAO-16 and they are not in the same league. Off-axis of course. On-axis even ball eyepieces are top...
IMO the goal should be to make it even better than ZAO-II, not how to get it cheaper.
ZAOs ER is perfect starting at 16, no need to improve there. What could be improved is the slight field curvature of the ZAO-II 16. No astigmatism however, unlike BGOs and SuperPlossls.
Like ZAOs, improvements should be achieved by special glass, polish and coatings, not by extra elements. For that we have Ethos, etc.

Hi Larry

Flat Field means what ? A eyepiece can be designed flat field only with a special telescope modell, becauase each scope has a diffrent curvative. So if you design a eyepiece for 1 scope to be flat field, it will not be flat field with another scope




Markus, flat means flat with flat field scope, such as EdgeHD, TV NPs, 65EDQ, etc. Medium and large refractors also have insignificant field curvature for narrow field eyepieces as orthos.

Hi Pedro

even the scopes you name are not flat field, they have a better field correction, but they are not flat field. Flat field means to me, at edge the same spot as in center

OK Markus, it is now the end of April. Shall we switch to the orthos?

Me too, but at 20mm and above only, to complement the ZAO-II.

Just wanted to put a plug for the TMB ED 1.8x Barlow...if you are looking for a great 1.25" barlow - this is it.

I use it with my ZAO-II's and Delos - amazing!

Is it better than the Zeiss barlow (sold with ZAO-II)?

Markus, I must say I was very surprised when you mentioned initially 8 weeks for production.
Taking so long to reply is not a good sign for the real production time...
In situations like this we realise the value of dealing with APM, with super fast response time and fast delivery time, including parts actually produced by APM like scope tubes.

Good things come to those who wait (at least sometimes...)

If the final product will be on EXACTLY the same quality level as the terrific ZAO-II, I will be very happy to accept that waiting time.
