Comparison

The 70mm Refractor wins decisively with a 71/100 overall score versus the Astromania's 52/100. These aren't close competitors; they're fundamentally different instruments serving different purposes. The single most important differentiator is optical performance across all viewing categories.
The 70mm Refractor delivers respectable scores in planetary observation (40/100) and deep sky viewing (40/100), while the Astromania Focal Reducer scores poorly in both categories at 20/100 and 19/100 respectively. Despite being marketed as a focal reducer for a Schmidt-Cassegrain system, the Astromania fails to excel at anything; it's a specialized accessory masquerading as a standalone telescope. The 70mm Refractor's lightweight design (1.4kg) and superior portability score (64/100) make it genuinely usable for casual observers, while the Astromania's equatorial mount adds complexity without corresponding benefits.
Buy the 70mm Refractor if you want a reliable beginner's telescope that actually observes celestial objects well. Buy the Astromania Focal Reducer only if you already own a compatible Schmidt-Cassegrain and need to reduce its focal ratio for specific purposes; it's not a primary instrument for anyone new to astronomy. The 70mm Refractor is the obvious choice for nearly all amateur astronomers.
