Comparison
The Celestron CPC Deluxe 800 HD emerges as the superior choice for most amateur astronomers, scoring 10 points higher overall with particularly impressive advantages in deep sky and astrophotography work. The single most important differentiator is optical design. The CPC Deluxe 800 HD's f/2.0 focal ratio versus the Advanced VX 8" EdgeHD's f/10.0 represents a fundamental advantage for light gathering and astrophotography, allowing the CPC to collect four times more light per unit time.
This translates directly into brighter deep sky views and faster imaging exposures, explaining the 18-point gap in astrophotography scores and 15-point advantage in deep sky performance. The Advanced VX 8" EdgeHD suits observers prioritizing planetary detail and those with strict budgets, since its longer focal length provides superior magnification at lower cost. The CPC Deluxe 800 HD deserves preference for anyone serious about astrophotography or seeking versatile deep sky performance, despite its $600 premium and marginally higher weight.
For most amateur astronomers, the Celestron CPC Deluxe 800 HD represents better long-term value. Its optical advantages in low-light conditions and proven astrophotography capabilities justify the investment if your interests extend beyond bright planetary targets.
