(Japan), is a F\/8 general purpose Ritchey-Chretien telescope with an Alt-Az mount. The TP2m is a join project between NCU(Graduate Institute of Astronomy, National Central University), SHAO (ShanghaiAstronomical Observatory), UNAM (Universidad Nacional Aut\u00f3noma de M\u00e9xico), and<br>ASIAA (Academia Sinica Institute of Astronomy and Astrophysics). One of the maingoal for the TP2m is to follow-up alerts released by the Vera Rubin Observatory\u2019sLegacy Survey of Space and Time (LSST). Nevertheless the TP2m can also be used forother forefront research areas proposed by the four partnered institutions. The TP2mwill be located in San Pedro Martir, Mexico, a site with excellent astro-climate.<\/p>\n\n\n\n<figure data-wp-context=\"{&quot;imageId&quot;:&quot;69e522391d89a&quot;}\" data-wp-interactive=\"core\/image\" data-wp-key=\"69e522391d89a\" class=\"wp-block-image size-full wp-lightbox-container\"><img loading=\"lazy\" decoding=\"async\" width=\"1023\" height=\"560\" data-wp-class--hide=\"state.isContentHidden\" data-wp-class--show=\"state.isContentVisible\" data-wp-init=\"callbacks.setButtonStyles\" data-wp-on--click=\"actions.showLightbox\" data-wp-on--load=\"callbacks.setButtonStyles\" data-wp-on-window--resize=\"callbacks.setButtonStyles\" src=\"https:\/\/www.astro.ncu.edu.tw\/ncutwom\/wp-content\/uploads\/2026\/04\/NCU2M-1.jpg\" alt=\"\" class=\"wp-image-184\" srcset=\"https:\/\/www.astro.ncu.edu.tw\/ncutwom\/wp-content\/uploads\/2026\/04\/NCU2M-1.jpg 1023w, https:\/\/www.astro.ncu.edu.tw\/ncutwom\/wp-content\/uploads\/2026\/04\/NCU2M-1-300x164.jpg 300w, https:\/\/www.astro.ncu.edu.tw\/ncutwom\/wp-content\/uploads\/2026\/04\/NCU2M-1-768x420.jpg 768w\" sizes=\"auto, (max-width: 1023px) 100vw, 1023px\" \/><button\n\t\t\tclass=\"lightbox-trigger\"\n\t\t\ttype=\"button\"\n\t\t\taria-haspopup=\"dialog\"\n\t\t\taria-label=\"\u653e\u5927\"\n\t\t\tdata-wp-init=\"callbacks.initTriggerButton\"\n\t\t\tdata-wp-on--click=\"actions.showLightbox\"\n\t\t\tdata-wp-style--right=\"state.imageButtonRight\"\n\t\t\tdata-wp-style--top=\"state.imageButtonTop\"\n\t\t>\n\t\t\t<svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"12\" height=\"12\" fill=\"none\" viewBox=\"0 0 12 12\">\n\t\t\t\t<path fill=\"#fff\" d=\"M2 0a2 2 0 0 0-2 2v2h1.5V2a.5.5 0 0 1 .5-.5h2V0H2Zm2 10.5H2a.5.5 0 0 1-.5-.5V8H0v2a2 2 0 0 0 2 2h2v-1.5ZM8 12v-1.5h2a.5.5 0 0 0 .5-.5V8H12v2a2 2 0 0 1-2 2H8Zm2-12a2 2 0 0 1 2 2v2h-1.5V2a.5.5 0 0 0-.5-.5H8V0h2Z\" \/>\n\t\t\t<\/svg>\n\t\t<\/button><\/figure>\n\n\n\n<p>The planned first-light instrument for the TP2m is a multi-color (rizy) simultaneousimager, at which light from the telescope was split into four beams using dichroicmirrors (DM).
