Comparison
The Celestron EdgeHD 800 OTA is the clear winner, scoring 81/100 compared to the Advanced VX 6" SCT's 40/100 despite identical pricing. The single most important differentiator is that the EdgeHD 800 OTA is an optical tube only, while the Advanced VX 6" SCT includes a complete mounted system. This explains the dramatic weight difference; 1.20kg versus 34.20kg.
You'll need to purchase a separate mount for the EdgeHD 800 OTA, but even modest equatorial mounts cost far less than the Advanced VX 6" SCT's inferior total package. The EdgeHD 800 OTA outperforms across every category: planetary observation (69 vs 30), deep sky (59 vs 14), astrophotography (66 vs 41), and beginner-friendliness (49 vs 21). The Advanced VX 6" SCT appeals only to budget-conscious buyers who absolutely need a complete, ready-to-use system and cannot afford separate mount purchases.
For serious amateur astronomers at this price point, the Celestron EdgeHD 800 OTA is the superior choice, offering exceptional optical quality and versatility once paired with an appropriate mount.
