Takahashi TOA150 Apochromat Refractor OTA

The TOA-150 is the top line model of the range of ortho apochromatic refractors, proposed by Takahashi. As usual, the Japanese company has manufactured one of the most beautiful and powerful telescopes that can be found on the worldwide market designed and produced without compromise.

Incomparable optics providing a high contrast apochromatic image and featuring reliable and robust mechanics, that is what the outstanding TOA-150 will provide to any amateur astronomers looking for the very best. No matter what you are looking for, from deep sky CCD imaging to high-resolution planetary visual observation, TOA-150 will bring you the best.

Genuine authorised Takahashi product with full UK warranty

The TOA-150 is asupplied complete with 7x50 finder, double tube holder, illuminated reticle and camera angle adjuster. In spite of its size and its weight (14.6kg), this refractor can be used on many mounts, including of course the EM400. This will allow the end-user to take advantage of the best night skies.

Triplet Ortho Apochromat Optics
The objective of TOA-150 (D=150mm, F=1100mm, F/D 7,3) is an air-spaced triplet of which two of the lenses consist of ED glass with very weak chromatic dispersion. Its optical design, that has gone through many years of R&D experiences, is a state-of-the-art. Due to its fast focal ratio, Takahashi engineers had to optimize the space between the lenses in order to minimize chromatic and geometric aberrations. The objective is assembled in a precise mechanical barrel, entirely adjustable. Collimation is easy to adjust and makes it possible to adapt perfectly optical requirements to the conditions of observation or imaging. The tube has a retractable dew shield as standard to enhance portability.

Oversized Focuser and Camera angle adjuster
As on the TOA-130F, the rack-and-pinion focuser has been reinforced and oversized, first to take completely advantage of the field of full light (90mm with the #67 field corrector !), to ensure a perfect rigidity of all the assemblies attached at prime focus and also to balance the tube, taking into account the very important weight of the objective. A balancing cradle, equipped with a handle, has been added to fulfill this function. The focuser is equipped with a camera angle adjuster for photo framing.
