Sky-Watcher Evolux 62ED Reducer/Flattener
Buy on Amazon
The Sky-Watcher Evolux 62ED Reducer/Flattener is a 0.9x optical accessory designed to eliminate field curvature and reduce focal length for improved astrophotography results with the Evolux 62ED refractor. It produces flat, sharp star fields across the full image sensor while shortening exposure times by reducing the effective focal ratio. Overall, it is a well-matched, purpose-built accessory that integrates cleanly into the Evolux 62ED imaging train.
