I am waiting breathlessly for the appearance of your reasonably priced large apo on the market
If you can pull this through I will be standing in the line to buy one as will many others 
Good Luck

Valery, I have read this thread with great interest. Good for you for coming up with a revolutionary design. You have the track record to pull this off. One of the things that concerns me with 200mm refractors is that they are generally quite heavy. I hope that you can solve the weight/tube flexure issues so that the scope is not only reasonable in price but is not too heavy or easily susceptible to tube flexure. If you can pull off theses parameters, I would be one of the people on your waiting list. Bob
Bob,
Tube weight minimizing was one of our main goal in this project. We will try to keep the weight down as much as possble.

i am mostly posting to add this to my favorite threads. an 8" f6.5 refractor with good color correction and affordable, what a dream. you could be a very rich person. I'll have to build a mount for mine.

Do you really expected this kind of a "dream scope" ever come true? It never was anything but a promise without any substance.
Optics are straightforward, there is no way to get around the reality.

Hey Valery, are you looking at producing a 6" F6.5 objective as well once you have the 8" scope underway? Man o man I'd be buying an objective for my scope right fast, I wish you all the luck in finalizing your design.

Right now we making a second sample with the tube mechanics.
I expect to be in time to look at Mars this spring through this telescope.
However the distance between one or two working samples to the serial manufacturing is not quite short and it is obvious, that we need to improve the technology to make objectives chaper and even better than now.

It doesn't sound like the bomb has exploded so much as that the fuse has been lit. (Much as I dislike the bomb metaphor.)

August 29, 2011 at 16:00 local time (14:00 Greenvich), the apochromatic H-bomb has finally exploded!
An 8" F/6.5 apochromatic doubled objective, made of the very simplest glasses - F1 - K8 (F2 - BK7 Schott), has been successfully tested in the laboratory at the optical bench with 220mm F=2500 mirror collimator.
No visible false colors on a thin string of a bright lamp when looking through a 50x microscope instead of an eyepiece.
The doubled objective has a Diffraction Optical Element (DOE) at it's rear surface - a so called Freshnel lens.
Such a combo - two lenses + DOE, allows to nullify a chromatic aberration - inherent to achromatic objectives. Sphero-chromatic aberration is also nullified in such a system.
We expect a complete telescope tested under a real sky within 5-7 weeks.
Valery Deryuzhin.
Getting close to seven months since the original detonation. Just sayin'

Ahemmmm.....
Maybe it wasn't an H-Bomb after all, but I would settle for a regular high quality C-4 bomb 
Valery, seriously , what about some progress report ?
something is got t'a give.....

To all jokers and mockers:
Diffraction Optical Element = DOE.
DOE-based 8" F/6.5 apo doublet has been made ALREADY with necessary accuracy and cleanliness. It delivers Jupiter and moon images as color free as reflector does.
I never saw better image of Jupiter in any another 8" aperture.
However this is stage-I of this project and it shows us that:
1. The technique we have developed for manufacturing of a Fresnel surfaces can support necessary level of precision and cleanliness.
2. The system works exactly as expected according to the design data.
3. The manufacturing cost + materials cost will not exceed our preliminary estimations. Of course in the case of serial production.
This is a great step ahead in this field. So far not one other manufacturer include such giants as Schott, Canon, Nikon, Zeiss etc, was able to create anything close to such level of Fresnel lens performance - far better than Rayleigh limit and in such size.
However the serial samples have to be of another design and we need to perfect the process itself - to make it cheaper, simplier and more reliable.
Being based on our experience, the next stage-II will takes at least 18+ months for the first sample of stage-II. One way or another, but we will reach the final success.
Fluorite doublets, if properly designed and made,I consider the best APOs for today. Therefore we took the decision to re-new our former fluorite APO line. This is not a big deal at all.
