Comparison
The Celestron Advanced VX 8" EdgeHD is the clear winner for most amateur astronomers. The single most important differentiator is performance versus price; the Advanced VX scores significantly higher across nearly every category while costing $2700 less. The Advanced VX's superior scores in planetary observation (57 vs 14), deep sky viewing (59 vs 14), and astrophotography (66 vs 34) reflect its larger effective aperture and better optical design for serious imaging and visual work.
The CPC Deluxe 1100 HD's only meaningful advantage is portability at 19.5kg versus 38.5kg, yet it severely underperforms the Advanced VX in actual observing quality. The Advanced VX 8" EdgeHD suits amateur astronomers seeking serious planetary, deep sky, and astrophotography capabilities without excessive cost or setup complexity. The CPC Deluxe 1100 HD appeals only to those who prioritize extreme portability over observing performance, though even then its poor scores suggest better alternatives exist in that category.
Buy the Advanced VX 8" EdgeHD unless you genuinely require a telescope light enough to pack into a car regularly. For most backyard observers, the Advanced VX delivers substantially better optics and performance at nearly half the price.
