With a 190mm aperture, it gathers about 740 times more light than the human eye, \u003cstrong\u003edelivering bright, detailed images.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp data-start=\"400\" data-end=\"720\"\u003eIts front meniscus lens, \u003cstrong\u003emade from high-quality glass\u003c\/strong\u003e, and spherical primary mirror form a Maksutov-Newtonian optical system—offering excellent image quality with high contrast, minimal aberration and a flat, coma-free field. This makes it particularly \u003cstrong\u003ewell-suited for astrophotography\u003c\/strong\u003e using DSLR or CCD cameras.\u003c\/p\u003e\n\u003cp data-start=\"722\" data-end=\"1013\"\u003eThe optical performance is comparable to that of an apochromatic refractor, but at a \u003cstrong\u003esignificantly lower cost.\u003c\/strong\u003e Unlike achromatic lenses, it produces images free from colour fringing. The closed-tube design also minimizes internal air currents, improving \u003cstrong\u003eimage stability during long exposures.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp data-start=\"1015\" data-end=\"1445\"\u003eThanks to the \u003cstrong\u003eintegrated meniscus lens\u003c\/strong\u003e, the design eliminates the need for diffraction-inducing spider vanes, and the 58mm secondary mirror provides \u003cstrong\u003eexcellent field illumination\u003c\/strong\u003e. With an f\/5.3 focal ratio and 1000mm focal length, it supports short exposure times and accommodates a wide range of targets. The field of view is approximately 1.4° (24.4mm) x 1° (17.5mm) when used with an APS-C (half-frame) sensor, such as those in Canon EOS cameras. \u003c\/p\u003e\n\u003cp data-start=\"1447\" data-end=\"1813\"\u003eA \u003cstrong\u003erobust 2\" Crayford focuser with fine adjustment\u003c\/strong\u003e ensures precise focusing, even with heavier cameras.
