K-DRIFT pathfinder: A compact telescope for observing faint galactic structures

Conventional telescopes are limited in detecting low-surface-brightness (LSB) structures, which are essential for studying galaxy evolution. Now, researchers have developed a new telescope system featuring a confocal off-axis design with three freeform mirrors, optimized for deep LSB imaging. This system enables astronomers to observe faint galactic features more clearly, revealing how galaxies evolve over time.
