Comparison
The ZWO Seestar S50 is the clear winner for most amateur astronomers. The fundamental differentiator is that the Seestar S50 is a fully autonomous smart telescope with GoTo and tracking, while the Sky-Watcher Quattro 150P is a traditional manual instrument requiring alignment and manual pointing. This automation gap translates directly into the score disparity; the Seestar S50 achieves 93 overall versus 63 for the Quattro. The Seestar S50's advantages extend beyond convenience.
Its 86/100 portability score and 2.5kg weight make it genuinely travel-friendly, whereas the Quattro's 7.67kg heft discourages casual transport. For beginners, the Seestar scores 71 compared to 34, reflecting how its intuitive smartphone interface eliminates the learning curve that frustrates new observers with manual telescopes. Both excel at astrophotography, but the Seestar's integrated smart features handle processing automatically. The Quattro's larger 150mm aperture grants superior light gathering for deep sky objects, but this advantage becomes irrelevant if the telescope stays in storage.
The Seestar S50 is the better investment for modern amateur astronomers seeking an instrument they will actually use regularly. Buy the Seestar S50 for practical, enjoyable observing; choose the Quattro 150P only if you specifically want manual operation and accept that its larger aperture requires significant commitment to setup and alignment.
