Telescope Zoom
Match each target to the smallest instrument that can see it, from naked eye to space telescope.
How to play
Pick the smallest instrument that can see the target — a perfect match earns 2 points, an oversized scope only 1, and too small sees nothing. Hint: limiting magnitude m ≈ 2 + 5·log₁₀(D/mm), so light grasp grows with aperture.
