Takahashi TOA-130S/F Triplet Ortho Apochromat
With its Ortho-Apochromat Triplet (TOA) concept, Takahashi gives a second youth to the refractors of large diameter, often confined with the planetary and lunar observation. Greatest accessibility with the imagery as well as the appearance of increasingly large and increasingly powerful numerical sensors obliges to make these telescopes much more general-purpose and compact, less restricted with planets and observatories.
The TOA-130 associates the extraordinary contrast of the images and the absence of chromatism of apochromatic refractors with a consequent diameter and a reasonable focal distance, allowing a general-purpose use as well for the planetary high-resolution as for deep sky imaging. In this last field, its optical design enables it to fully use the capacities of all imagers of the market (35mm SLR/DSLR or 6x7 cameras but also wide-field CCD imagers).
The TOA-130 is available in S version, with traditional rack-and-pinion focuser, and in F version, with oversized rack-and-pinion focuser (and camera angle adjuster), perfectly adapted to imaging. For this optical tube of 1015mm length, of 130mm of diameter and of almost 10kg, configurations exist on EM-200 or EM-400 equatorial mountings.
