Apochromatic telescope 104mm triplet for astrophotography is a professional refractor for those seeking uncompromising image quality. With an air-spaced 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.
This apochromat forms the heart of any serious astrophotography setup. Thanks to the large 104 mm aperture, an f/6.25 focal ratio, and a robust 2.9″ focuser, this telescope is suitable for cameras with large sensors, such as APS-C and full-frame.
✓ Razor-sharp stars to the edge of the frame – even with full-frame sensors
✓ No chromatic aberration thanks to FPL-53/FPL-51 triplet optics
✓ Fully illuminated image field with 2.9″ focuser and M74 connection
✓ Perfect for deep-sky astrophotography and high-res planetary imaging
✓ 360° rotatable focuser for optimal camera framing
✓ Aluminum carrying case included
This telescope is designed for stability, precision, and portability. The velvet-black CNC tube eliminates internal reflections, while the extendable dew shield preserves contrast. The entire unit is compact enough (63.5 cm long) to be used as a mobile setup, without compromising performance.
