Comparison
The 150EQ Newtonian emerges as the winner overall, despite both sharing identical 150mm apertures. The single most important differentiator is the equatorial mount with motorized tracking on the 150EQ, which fundamentally changes what these telescopes can accomplish. This feature alone explains its 12-point overall score advantage and dramatic 32-point lead in astrophotography capability, making long-exposure imaging and celestial tracking feasible rather than frustrating.
The Sky-Watcher Heritage 150P excels as a pure visual instrument with its superior Dobsonian mount delivering smooth, intuitive pointing and setup simplicity; choose it if you prioritize uncluttered observing sessions and maximum portability for dark-sky trips. The 150EQ serves observers committed to astrophotography or those wanting to pursue imaging without purchasing entirely separate equipment; its equatorial design and tracking make it genuinely capable for long exposures despite being heavier and less portable. For most amateur astronomers, the 150EQ's astrophotography credentials and modest $55 price advantage justify the extra weight and learning curve of an equatorial mount.
However, visual-only observers who value ease of use and plan frequent travel should stick with the Heritage 150P.
