Oil vs. Air Spaced Tripletts

Posted By Markus Ludes

we have quite a few owners of large airspacest ED Apos, 8", 9" and 10" in USA and all reporting stunning images. I self have a 12"F/12 at my backyard and it showed mars with detail not seen on any of the great images

So whatever experience Roger has, its diffrent from many others which are not less valuable

WO fluorite doublet design

Posted By Markus Ludes

William Optics do not claim to use Calcium Fluorite, he told us, this Fluorite douplet use a modern chinese fluorite, whatever he means with that.
The design is good in any case, as good as the Sky 90 who use Caf2, so nothing to worry about

Super Mono production update?

Posted By Markus Ludes

Hi Kurt

the situation is as follow:

4 mm up to 9 mm plus the barlow arriving in next days again.
10 mm up to 16 mm are delayed for around 6 to 8 weeks, because the full run of glases have been rejected due a problem, which I don't know off.

I am offering what I can get

SuperMono update

Posted By Markus Ludes

Hello Friends

after a very raining august we got back the summer with great blue sky and many sun, so I made in the day time my main job and took off the afternoon from work to observe sun and in evening to watch the partiel Mooneclipse and play with telescopes and have a barbeque and drinks in the evening and did not went through all the internet places to see where I am in dept of a reply .

So please allow me the little delay in reply.

Mono Status: We have enough Monos of all focallenghtes under delayed backorder to fullfill all reservations and preorders, do not worry.

The 12,14, and 16 have been delayed since early this year so some company intern reasons at the manufactor side.

The last time I talked with them in early august, the forecase was a delivery for end of this month september for all focallengthes. Its a promisse , not a guarantee .

When the contracted Mono's are fully sold and we still see a need , we can order more in future , but for higher price, because the price depends on the ordered total quantity.

I have so many customers on my backorder list, that I simply cannot take every 1 or 2 weeks 1 or 2 days off to send a mail info about the status.

Everybody on my list will get his mono's, when I have them in my hands, I contact you, than you can say , yes I still want them , or no , do not need them anymore

I hope thats ok for everybody

wish you all the same blue clear sky as I have at moment :-) ,

Market Flooded???

Posted By Markus Ludes

I just came home from the Photokina in Colon, there you can find 5" Triplet apo F/8 on GEM for $ 800 only , but you can also find 5" for $ 3,000 and startest of both are such good, that I would not buy any of them , not even for $ 500.

You could find Items at the Photokina, which you know from some well known and respected manufactors, who claim they make this items indoor at here own company .

This Photokina teached me do not bvelieve anymore any word of most manufactors who claim, we make it ourself.

But this photokina teached me also that some companys are able to sell very very nice looking telescopes with chunk optics and still have a big customer support.

I learned China is still light years ahead for supply of real high end optics and high end mechanics.

greatings from the Photokina,

SuperMono update

Posted By Markus Ludes

hello All,

we got a new update about the Super Mono eyepiece delivery this week and for those who are under hurry to get them, it does not look such good.

Let me pread or exoplain the old and now new situation.

We have a big Contract with Berliner Glas in Berlin for such eyepieces.Many parts have been made in door , but some also outsourced .

The recend delay we have is, that due our super strong requirements on cosmetic and quality of the Super Multicoating about 50% of the glas lenses has been not good enough for assembling as a eyepiece. Thereoftre we got this year from the remind quantity of the contract much less then we wanted.

New lenses have had to be polished to replace the bad coated once and to be able to fullfill the contract.

This week I got a new testing plate of a new multicoating and new transmission curved from a company which looks very promissing that they can do the required super high quality coating on such small lenses.

In Trade Berliner Glas informed me the promissed delivery of end of september, earl< october have been post phoned again backwards, at moment with no fixed date.

So what is fixed is the remind quality , Berliner Glas will deliver us and thats enough to fullfill from my side all excisting backorders.
Some focallengthes are fully sold out , if we must make more of the sold out, we need to ask higher prices.

So the situation for those of you who has a backorder running with me, and thats are a lot of you , will get here eyepiece later , but you will get it. If you want to canle your backorder due this message , drop me a email, it okay and no problem.

So if you want your backordered Mono , even somewhat later , fine, do no nothing, I have all of you on my list.

I am sorry for this not best news , but at least such good news, that you know now again a bit about the reason for the delay and that you get your Super Mono for shure, if you wait till we have them ready for shipping

best wishes
