Sky-Watcher EvoStar 90 EQ2

A 90mm achromatic refractor at f/10 — the classic entry-level refractor configuration that has served beginner astronomers well for decades. The long focal ratio makes chromatic aberration (the coloured fringing seen on bright objects) almost imperceptible at normal magnifications, and the EQ2 equatorial mount teaches you real sky mechanics without being overly complex. Lunar views are crisp and high-contrast, and at high magnification the Moon's craters and mountain ranges become genuinely absorbing. Saturn's rings are visible at 50×, and by 100× this scope delivers the views that make new astronomers gasp. Solid, honest, and predictable.
