Reveal more of the sky. This 8.3 MP sensor, with large 2.9 μm pixels perfectly matched to Vespera II’s focal length, captures finer details (2.39″/pixel) and delivers cleaner images even under low-light conditions.

Black-anodized tube for internal reflection suppression

Get deeper contrast in your images. The matte, blackened tube prevents stray light from bouncing inside, so faint nebulae and galaxies stand out with greater clarity.

A unique passive radiator around the sensor

Capture cleaner, smoother details. The cooling system lowers the sensor’s temperature naturally, reducing noise so you can reveal faint structures with less post-processing.
