99.2% at the wavelengths human vision cares about most, putting it right alongside Takahashi's flagship TOA series in optical performance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor correction that beats the old legends.\u003c\/strong\u003e Chromatic aberration in the blue and violet wavelengths is cut by a third compared to the classic Fluorite-based FS-102 and FS-128, so stars stay tight and colors stay true.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eA triplet built to travel.\u003c\/strong\u003e Three lenses in three groups, with an S-FPL53 ED element at the center and hard multicoatings throughout, are mounted in a 3-element barrel engineered to hold optomechanical alignment through transport bumps and swinging temperatures.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLightweight and compact for a 120 mm apo.\u003c\/strong\u003e A retractable dew shield keeps the tube at just 870 mm collapsed (990 mm extended), all at a manageable 6.7 kg, so a serious aperture doesn't mean a serious hassle to haul around.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOne tube, four focal setups.\u003c\/strong\u003e Shoot native at 900 mm (F\/7.5), add the TOA-35FL field corrector for 882 mm (F\/7.3) native-focus imaging, drop in the TOA-35RD reducer for a faster 672 mm (F\/5.6) deep sky setup, or reach for the EXT-ED1.5X extender to hit 1350 mm (F\/11.3) for high-resolution planetary and lunar work.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuilt for modern imaging trains.\u003c\/strong\u003e The assembly meets the rigidity and flexibility demands of today's digital cameras and the latest generation of CCD cameras, so your imaging chain stays solid all night.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrecision hardware from a name astrophotographers trust.\u003c\/strong\u003e Like everything else Takahashi builds, the TSA-120 is engineered
