Comparison
The Celestron Advanced VX 6" Newtonian edges out the Sky-Watcher FlexTube 200P GoTo for most amateur astronomers, though this isn't a clean victory. The critical differentiator is optical quality paired with mount stability. The Advanced VX's equatorial mount provides superior tracking for both visual observing and astrophotography, reflected in its 76/100 astrophoto score versus the FlexTube's 44/100.
The equatorial design also handles planetary observation better, scoring 50 versus 59 points in favor of the Sky-Watcher. However, the larger 203mm aperture of the FlexTube delivers significantly more light gathering, making it genuinely superior for deep-sky objects if you can tolerate its Dobsonian limitations. Buy the Celestron Advanced VX if you prioritize astrophotography, planetary detail, or plan frequent travel with your scope.
Buy the Sky-Watcher FlexTube if you want maximum light-gathering power on a tight budget and don't mind the heavier, less portable Dobsonian design. The Celestron Advanced VX 6" Newtonian is the safer choice for the typical amateur astronomer seeking balance between portability, astrophotography capability, and visual performance.
