Comparison
The Celestron CPC Deluxe 800 HD is the clear winner for nearly all amateur astronomers. With an overall score of 78/100 versus the CGX 1100's dismal 38/100, this isn't a close decision. The single most important differentiator is optical performance and versatility; the CPC Deluxe 800 HD excels across planetary observation (64/100), deep sky viewing (74/100), and astrophotography (84/100), while the CGX 1100 struggles in all three categories with scores in the teens and low forties.
The CPC Deluxe 800 HD should appeal to serious hobbyists willing to invest in stationary observing setups, offering exceptional value at $3399 with superior optics and GoTo convenience. The CGX 1100 might only interest those with unusual portability constraints, though its weak performance scores make it hard to recommend even then. At $1600 more, the CGX 1100 delivers dramatically inferior results across every meaningful metric.
The CPC Deluxe 800 HD's 203mm aperture provides the optical advantage that makes genuine difference at the eyepiece, justifying its premium.
