Takahashi TSA102S Apochromat Refractor OTA

The Takahashi TSA-102 Apo refractor has became the worthy heiress of the legendary FS-102. The apochromatic objective of 102mm of aperture (F/8) took its classical optical design with Fluorite doublet for a ED triplet set in a simple barrel, whose results are quite as flattering. The TSA-102 remains the most general-purpose telescope of the Takahashi range, adapted not only for planetary high-resolution visual observation but also for deep sky imaging, while still being easily transportable. Premium Japanese triplet optics designed to provide excellent colour correction and contrast.



Genuine authorised Takahashi product with full UK warranty

As usual with Takahashi, the TSA-102 profits by a very vast range of accessories, adapted to all amateur uses. Moreover, many amateurs have made the proof of its versability in fields as varied as planetary observation or deep sky imaging.

This TSA-102S is equipped with a retractable dew shield and is supplied with a Takahashi 7x50 finder, tube ring clamshell and can accept 2" or 1.25" accessories.

Optical design and TSA-102/FS-102 compared chromatic correction
Takahashi has developed an air-spaced ED triplet objective (3 lenses in 3 groups). This triplet consists of a lens of ED glass (S-FPL53) laid out between 2 crown lenses air-spaced by a mean chock. Like the TOA objective, optics have been designed and calculated according to the high requirements of the current numerical imaging.
The change of optical design between FS-102 and TSA-102 has not spoiled the chromatic correction, on the contrary. This new ED design shows its full effectiveness, including in the intransigeant planetary imaging use.
