Comparison
The Sky-Watcher EvoGuide 50DX is a specialized guide scope; the 150EQ Newtonian Reflector is a general-purpose telescope. This distinction makes the 150EQ the clear winner for most amateur astronomers, scoring 80/100 overall against the EvoGuide's 62/100. Aperture is the single most important differentiator. The 150EQ's 150mm aperture gathers three times more light than the EvoGuide's 50mm, delivering substantially brighter views of deep sky objects and superior planetary detail.
The EvoGuide's 50mm aperture fundamentally limits its performance for visual observation. The Sky-Watcher EvoGuide 50DX is designed for experienced astrophotographers as a guide scope for autoguiding during long exposures. The 150EQ Newtonian Reflector suits beginners and intermediate astronomers seeking versatile deep sky and planetary viewing with motorized tracking. Buy the 150EQ unless you already own a main imaging telescope and specifically need an autoguiding solution.
Its equatorial mount with tracking, larger aperture, and superior scores across astrophotography and deep sky categories make it the better investment for standalone observing. The EvoGuide excels only in portability; weight alone should not drive your decision.
