The Sky-Watcher 120/900 EvoStar ED DS-Pro OTA is a powerful apochromatic refractor that excels in color correction, contrast, and sharpness. This makes the instrument particularly suitable for advanced observers and serious astrophotography. Thanks to the FPL-53 ED glass and high-quality Schott crown glass, this telescope delivers images with minimal chromatic aberration and impressive detail rendering — even at high magnification.
The combination of a 120 mm aperture and a focal length of 900 mm (f/7.5) provides an excellent balance between light gathering, resolution, and speed for photography. With a light gathering power 294x higher than the naked eye and a resolution of 0.96 arcseconds, you can see fine structures on the Moon, Saturn’s rings, Jupiter’s cloud bands, and deep-sky objects like the Orion Nebula and the Pleiades.
The optics feature a 2-inch Crayford focuser with 1:11 micro-adjustment, essential for precision in astrophotography. The 2″ zenith mirror and 28 mm LET eyepiece ensure comfortable visual observations. The included aluminum carrying case provides optimal protection during transport.
In its OTA configuration, this model is suitable for users who already own an appropriate mount. Thanks to its compact design with a relatively short tube, this refractor is also suitable for use on medium EQ5 mounts — without instability or overload.
What Can You See with it?
✓ Moon: razor-sharp details, edges, and shadow structures
✓ Planets: clear rings of Saturn, cloud bands on Jupiter, Mars at opposition
✓ Deep-sky: star clusters, bright nebulae, and star fields (Orion, Andromeda, Pleiades)
✓ Suitable for astrophotography with field flattener and DSLR or astrocam
