Apochromatic telescope 104mm triplet for astrophotography<\/strong> is a professional refractor for those seeking uncompromising image quality. With an air-separated triplet objective (including FPL-53 and FPL-51 elements), this telescope offers maximum color correction and sharpness - essential for astrophotography and visual deep-sky observation.<\/p>\n\n\n\n

This apochromatic is the heart of any serious astrophotography setup. With a large 104mm aperture, an f\/6.25 aperture ratio and a robust 2.9\u2033 focuser, this telescope is suitable for cameras with large sensors, such as APS-C and full-frame.<\/p>\n\n\n\n

\u2713 Sharp stars all the way to the image edge - even with full-frame sensors
\u2713 No chromatic aberration thanks to FPL-53\/FPL-51 triplet optics
\u2713 Fully exposed field of view with 2.9\u2033 focuser and M74 connector
\u2713 Perfect for deep-sky astrophotography as well as high-res planetary shots
\u2713 360\u00b0 rotatable focuser for optimal camera framing
\u2713 Aluminum transport case included<\/p>\n\n\n\n

This telescope is designed for stability, precision and portability. The velvet-black CNC tube eliminates internal reflections, while the retractable dew cap preserves contrast. The assembly is compact enough (63.5 cm long) to be used as a mobile setup, without compromising on performance.<\/p>\n\n\n\n
