TakFSQ-106 is the modified Petzval design that employs two flouriteelements, the two widely seperated rear elements which correct fieldcurvature and astigmatism and produce a flat field. An amazing 88mmimage circle that fully illuminated 35mm, 645, 6x7 or even 4x5" mediumformat camera with minimum corner darkening. The 4" O.D. focuser withbuilt-in camera angle adjuster that permits 360 rotation of the camera,thus FSQ-106 is a versatile astrograph.
When used with the Extender-Q 1.6x, the FSQ-106 becomes a greatlunar & planetary scope. Without extension tube only 555mm (22") inlength, this portable telescope is a good choice for eclipse chaser.
The FSQ-106 is truly a state-of-the-art flourite APO refractor, it sets a new standard for innovation & color correction.
Baker Ritchey Criteion (BRC) is specially designed for astrophotographypurpose. Wide & flat field design, 4x5" format camera can be used,thus achieving 4.5field. With aperture of 10" plus CCD imagingtechnology, stellar image as fine as 2 microns & as faint asmagnitude 15 can be recorded
This Tak EQ mount is the 2nd ultra-portable since Tak sky patrol EQmount. It is capable of loading a 6cm telescope with a 6x7 camera or 2cameras side by side, the optional polar alignment scope is attached atthe lower side of R.A. axis
FCT-250 is the largest triplet fluorite APO Takahashi ever made. Itweighs 85kg, 2.9m in length. EM-3500 Temma EQ mount fastest slewingspeed 350x sideral rate, can be operated by a PC or hand controller.Its loading capacity 150kg, total system weighs 730kg.
Since first launch until now, this EM-200 series mount has almostcelebrate its 25th anniversary. Temma is a Japanese word (ぱ皑) with GOTOcapability, slewing at 700x sideral rate when operated at 24V, which isthe fastest of all mass production Tak EQ mount. RS232C cable &Pegasus software comes as standard accessory, when connected, thismount can be controlled by PC. Optional keypad controller for EM-200Temma is available. All versions of EM-200 mount are compatible withautoguiding function
With a maximum loading of 30kg & fastest slewing speed at 350x,oscillation frequency 200PPS, making NJP Temma-2 the highest accuracyEQ mount in its class. It uses a side loading plate to insure that asthe mount is elevated and depressed for proper polar alignment, itmoves in a straight line. The only commercial available mount thatcomes with this unique & useful feature. Manual slow motion controlis an added feature of NJP
Sky-90 is a short tube fluorite apochromat from Tak, focal ratio off/5.6 & tube length of 350mm, which is ultra-portable &versatile. It is fully multicoated and uses knife edged baffles toproduce highest contrast. The 2.5" focuser & newly designedcompression ring adapter allows the use of any combination of 1.25" or2" diagonal-eyepiece combinations.
When coupled with the f/4.5 flattener/ reducer, the Sky-90 can beused as an astro camera or ultra-wide field instrument. Besidesstar-gazing, its very short length makes it a portable high qualitytelescope for birding or for toal solar eclipse photography.
The Sky-90 fits easily into any airline overhead compartment. Theoptional rigid soft case provides protection for this 3.2kg instrument.
A Sky & telescope review called it "an ideal travelscope formobile observers, providing maximum performance at minimum size." Itmakes a great traveler scope that you can stow away anywhere

This 40cm (16") reflector is the largest of all Takahashi telescope
EM-3500 Temma is the top of the line of Takahashi equatorial mount
Themost successful & popular Tak EQ mount ever built, top slewingspeed 150x sideral rate (24V), tracking precision at 5", easy polaralignment, illuminated polar scope, capable for autoguiding, extremelysmooth tracking in both axis thanks to installation of high precisionenhanced bearing, comes with two 5kg counterweight, maximum loading16kg

This Triplet Orthoscopic Apochromat (TOA) complete separated system (3elements 3 groups) uses extraordinary dispersion (ED) glass, resultedin the whole spectrum with evenly correction of aberration. Thechromatic abberation is corrected perfectly from g~c line (436nm~656nm)of visible spectrum is controlled within 1/100mm p~p measurement. Thisnegligible residual color is especially good for CCD photography
TOA-130 have two versions: TOA-130S 2.7" focuser (10kg) & TOA-130F 4" focuser (11.4kg)
4x5" medium format camera can be used without vignetting when field flattener applied
Standard accessory: tube holder, 7x50 finder, 2" extension tube, 1.25" compression eyepiece holder, tube counter balance ring
