Comparison
The Unistellar Odyssey Pro is the clear winner for most amateur astronomers, though the choice depends on your specific priorities. The single most important differentiator is the Odyssey Pro's smart telescope technology combined with its exceptional portability; it weighs one-third of the Celestron while delivering superior overall performance and astrophotography capabilities.
The Celestron CPC 1100 StarBright XLT GPS Schmidt-Cassegrain 2800mm Telescope excels only in planetary observation and raw light-gathering power, but its 24kg weight and poor beginner score limit its appeal. Buy the Celestron CPC 1100 if planetary observation is your sole focus and you have a permanent observatory setup.
Buy the Unistellar Odyssey Pro if you want versatility, ease of use, integrated smart features, and the ability to actually transport your telescope to dark skies. The Odyssey Pro's significantly higher scores across beginner, astrophotography, and deep sky observation, combined with its genuine portability advantage, make it the more practical choice for the vast majority of amateur astronomers seeking a serious instrument they will actually use regularly.
