Omegon 104 mm Triplet Refractor

Apochromatic telescope 104mm triplet for astrophotography 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.

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″ focuser, this telescope is suitable for cameras with large sensors, such as APS-C and full-frame.

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

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.

Application

• Astrophotography (deep-sky & planets)
• Visual observation of nebulae, clusters, moon and planets
• Suitable for advanced users with EQ mounts

What you can see with it

✓ Details in emission nebulae (such as the Orion Nebula, Veil Nebula)
✓ Spiral arms in galaxies at longer exposures
✓ Rings of Saturn, cloud bands on Jupiter
✓ Double stars and open star clusters with extreme sharpness contrast
