    Default Agema Optics



    Has anyone seen one of these scopes yet?
    They are built in Wheat Ridge, Colorado and if the charts they post are accurate they look to be on par or better than Takahashis!?!?
    Nice looking scopes though

    Hello Gabby,

    a problem might be the blog page of Dec 4th, with the Strehl curves comparison on doublets from other manufacturers - looks like tweaked a bit for marketing
    The high performance of the Agema doublets in blue is surprizing, and it would be welcome, especially in the astrophotography. Herewith arises a question, where do the glass materials with the extrra low dispersion in blue come from? Military surplus?, LZOS?
    One should not oversee, that the Agema refractors are with F/8 - F/9 not really fast, making high Strehl values easier to achieve.

    All in all, this is a very interesting info worth of keeping eyes on Agema.

    Thanks for sharing,

    JG

    I agree JG, looking at the posted graphs generates more questions than answers to me.
    I do have the feeling that the numbers may have been tweaked a little as Canon/ Takahashi have been working flourite for many years and I am sure they have managed to get the most from it as possible.
    Possibly newer coatings also shifting the spectrum a bit as Vixen does with their new scopes?
    The Zeiss APQ has been held as the scope to match/ beat for apochromatics for a long time so I would imagine a scope that can better it as this graph shows would be generating more discussion than I have found.
    Even Thomas Back only said his scopes compared/ matched the Zeiss but he never claimed to better it.

    Thanks for this Gabby: they look really nice scopes. I would hope they are on a par with Takahashi: the 130SD would be quite a bit more expensive for me in Australia than a Tak TSA120 triplet..., and about the same price as the Tak TOA 130NS triplet.

    The posted chart for strehl looks to be quite vague, but really once you get over the .95 mark it doesn't make much difference! (Certainly not for visual work.)
    I note that Takahashi claim a peak strehl for their TSA102 of 0.999 at 550nm, 0.94 at 680nm, and 0.93 at 448nm (see: Takahashi TSA-102 refractor optical features )

    All the best,

    Dean

    The FS/TSA-102mm are considered by some as optical nirvana for visual, I would love to have one after using one for an evening.
    These could be some very nice scopes and I am looking forward to finding some reviews.

    I just found this from the owner of Agema Optics:
    I guess you know me very well. Agema Optics is my third company.
    The first one was Technical Optics in Ukraine, 1993-1998 - I produced optics for local customers and also for Jim Burr, Tom Dobbins and Yuri Petrunin.
    The second - TEC, 1998-2011 - I designed all models, set up optical production and produced optics for 13 years.
    The third - Agema Optics - I am planning to make more great telescopes. I have MD in optics and over 30 years experience in optical manufacturing. Optics is my life!

    Thanks Gabby for tracing Agema!

    So I have not been far away with my LZOS guess. Their glass materials standards differ from what we are using.

    I think, that lots of us would be ready to pay even the high price for the 180mm really fully corrected APO doublet - just 2 lenses, no oil spaced triplet, no added complication.

    I agree with Dean,
    that 0.95 Strehl in the full visual spectral range is by far enough. As always, the problem is in blue (400nm - 500nm) where we have the best visible spectral emission lines, and where the galaxies and the details inside (spiral structure) emit most of the visible light. The galaxies are blue - not green or yellow, and that's where we need the best performance of the telescopes (and of the eyepieces).

    Best,

    JG
