Celestron NexStar 5SE vs Sky-Watcher EvoStar 100 APO Doublet Refractor

The Celestron NexStar 5SE is the clear winner for nearly all amateur astronomers. The single most important differentiator is the GoTo computerized mount with tracking capability; the Sky-Watcher EvoStar 100 APO lacks motorization entirely, making it significantly less practical for modern observers who value convenience and observing efficiency. The NexStar 5SE dominates across every performance metric.

Its Schmidt-Cassegrain design delivers superior planetary and deep-sky viewing through a versatile f/10 focal ratio, while the computerized equatorial mount eliminates tedious manual tracking. The overall score of 78 versus 30 reflects real-world usability differences that compound over time. Beginners especially benefit from the NexStar's automated alignment and tracking systems, which reduce the learning curve substantially.

The Sky-Watcher EvoStar 100 APO should only interest observers committed to manual tracking who prioritize optical purity from an apochromatic refractor design; however, its abysmal scores across all disciplines suggest it may have significant optical or mechanical issues worth investigating before purchase. Buy the Celestron NexStar 5SE unless you have specific reasons to prefer manual alt-azimuth observing and can verify the Sky-Watcher performs acceptably in person. The NexStar 5SE is the obvious choice for the vast majority of users.
