Takahashi FSQ-80FC
\n\u25bapre\u00e7o de lan\u00e7amento!<\/em><\/strong><\/p>\n

O FSQ-80FC apresenta objetiva de 5 elementos em 5 grupos.
\n\u25baDois elementos de fluorite s\u00e3o usados \u200b\u200bno grupo tripleto frontal para suprimir a aberra\u00e7\u00e3o crom\u00e1tica,
\n\u25ba o grupo dupleto traseiro atua como um sistema \u00f3ptico de aplanamento de campo.
\nEste design avan\u00e7ado combina a excelente qualidade visual no eixo da s\u00e9rie TOA com a caracter\u00edstica de campo amplo e plano da s\u00e9rie FSQ.<\/p>\n

\u25baFSQ stands for Flat-field Supreme Quintuplet:<\/strong><\/p>\n

Although the FSQ-80FC is designed as a high-performance astrograph, it also delivers <\/em>outstanding visual performance.<\/em>
\nDespite its relatively fast F5.6 optical system, the telescope achieves an on-axis visual <\/em>Strehl ratio of 99.7%, exceeding even the TOA series flagship models in this metric.<\/em>
\nBoth chromatic aberration and spherical aberration are corrected to an extremely high <\/em>level, producing an image quality that can effectively be described as aberration-free.<\/em>
\nEven at very high magnifications, there is no detectable color fringing caused by the <\/em>telescope optics, allowing high-contrast observation of bright objects such as the lunar <\/em>limb and planets.
\nIn addition, the optical system maintains excellent correction across <\/em>the entire field of a 2-inch eyepiece, ensuring sharp and clean views from low to high <\/em>magnifications.<\/em>
\nTo support visual use, the telescope provides 159 mm of back focal length from rear end <\/em>of focuser, allowing infinity focus even when using the optional 50.8 mm diagonal mirror.<\/em><\/p>\n
