Takahashi FSQ85 Apochromat Refractor OTA
Ref: TQE8500
£3,449.00
With the success of short refractors and improvement of the performances of CCD and DSLR cameras, Takahashi introduces the FSQ-85ED, more itinerant than the FSQ-106ED model, and intended for deep-sky and wide field photographers. The FSQ-85ED is based on the same ED glass Petzval quadruplet design as the FSQ-106ED model, but offering a focal length of just 450mm and a photo field of 5.6°, which is ideal for astro imagers. It is equipped with an oversized rack-and-pinion focuser and an independent camera angle adapter. An optional focal reducer is also available in order to transform the refractor into a true astronomical teleobjective with a focal length of 328mm and with a focal ratio of 3.9, providing a field of view of 7° and a 40mm image circle.
Genuine authorised Takahashi product with full UK warranty
Weighing only 4kg without accessories, you will not need a heavy mount. It becomes easy to take pictures of the deep-sky while transporting your telescope under the best skies. Complete with 6x30 finder, tube ring and camera angle adjuster.
Four element optics
The FSQ-85ED modified Petzval quadruplet design is the same as the FSQ-106ED one. It has a built-in flattener inside the optical tube, offering a field of 5.6°, essential for taking quality pictures. It is thus not necessary to add any other optional accessory. With a focal length of 450mm, the image circle is 44mm width.
Oversized focuser
The FSQ-85ED is equipped with an oversized rack-and-pinion focuser, just like the 106ED. However, the camera angle adjuster has been taking apart from the focuser to come back to a more traditional position where accessories are screwed on focuser tube. The rack-and-pinion has been oversized on purpose to gain in precision and effectiveness. This focuser is a model of precision. It is driven by two focus wheels with a 1/7 microfocuser.
