The Skywatcher Focal Reducer for Evostar 72ED 0.85x is an essential optical accessory for avid astronomers. Specifically designed for the Sky-Watcher Evostar 72ED APO refractor telescope, it significantly enhances your astrophotography experience.
Key Features:
- Compatibility: Works seamlessly with both APS-C and full-frame camera sensors, although APS-C is recommended for the best results.
- Focal Length Reduction: Reduces the native focal length from 420 mm (f/5.8) to approximately 355 mm (f/4.93), making your optical system faster.
- Exposure Time: Decreases required exposure times by about 38%, allowing for quicker imaging without compromising quality.
- Field of View: Offers an expansive view of approximately 5.8° x 3.87° with full-frame cameras, and around 3.79° x 2.53° with APS-C sensors.
- Back Focus: Requires a precise back focus distance of 55 mm for optimal performance.
- Mounting: Includes a thread-on adapter for secure attachment to the focuser, with a male M48x0.75 thread for various camera connections.
By utilizing this focal reducer, astrophotographers can not only speed up their imaging sessions but also achieve a flatter and well-corrected field of view. The optical correction features ensure sharp stars and minimal optical distortions, making it a must-have for deep-sky imaging.
