Comparison
The Celestron CGEM II 1100 is the clear winner for serious amateur astronomers. With an overall score of 79/100 versus 45/100, it outperforms the Advanced VX 11" across nearly every category, delivering superior planetary observation, deep sky viewing, and astrophotography capabilities. The single most important differentiator is the CGEM II's advanced equatorial mount with tracking capability, which enables precise celestial alignment and sustained observation without constant manual adjustment.
This superior mount engineering directly translates to its 77/100 planetary score and 65/100 deep sky score. Buy the Celestron Advanced VX 11" f/10 Schmidt-Cassegrain Telescope if you prioritize affordability and want a competent telescope for casual observing. Purchase the Celestron CGEM II 1100 if you're committed to serious planetary work, astrophotography, or extended deep sky sessions where tracking accuracy matters significantly.
The CGEM II 1100 justifies its 500 dollar premium through substantially better performance in all meaningful categories. Its 46/100 beginner score suggests a moderate learning curve, but patient newcomers will find the investment pays dividends as they develop their skills and expand their observing ambitions.
