Comparison
The Sky-Watcher Heritage 130P is the better choice for most amateur astronomers, though the decision depends on your priorities and setup constraints. The single most important differentiator is portability and ease of use. The Heritage 130P weighs 8.69kg compared to the HSL 150EQ's 18.10kg, and its Dobsonian mount requires no polar alignment or power source. The equatorial mount on the HSL 150EQ adds significant complexity and weight, making it less convenient for casual observing sessions.
While the HSL 150EQ's larger 150mm aperture provides a theoretical advantage in light gathering, the Heritage 130P's f/5 focal ratio and superior optical design compensate effectively. The Heritage 130P excels across practical categories; it scores higher in beginner compatibility (41 vs 33), planetary observation (45 vs 42), deep sky viewing (46 vs 40), and portability (56 vs 41). Both perform modestly in astrophotography, though neither is purpose-built for imaging. Buy the Sky-Watcher Heritage 130P if you value ease of setup, portability, and genuine observing satisfaction.
Buy the HSL 150EQ only if you have a permanent observing location and specifically need the equatorial mount's tracking capability for planned astrophotography sessions. The Heritage 130P represents superior value; it costs less, weighs half as much, and delivers better real-world performance for typical backyard astronomy.
