Αξεσουάρ Τηλεσκοπίων Skywatcher ED80 Focal Reducer 0.85x

The Skywatcher ED80 Focal Reducer 0.85x is an exceptional optical accessory crafted for the Sky-Watcher ED80 series refractor telescopes. It significantly improves imaging performance by reducing the telescope's focal length by a factor of 0.85x, transforming the focal ratio from f/7.5 to approximately f/6.3. This adjustment enlarges the field of view and allows for quicker astrophotography exposures.

One of the standout features of this focal reducer is its ability to enhance field-edge correction. It effectively minimizes optical distortions and flattens the image field, contributing to better overall image quality across the frame.

• Focal Reduction Factor: Reduces f/7.5 to f/6.3 for the ProED/Evostar 80ED APO telescopes.
• Back Focus: Requires 55mm of distance for optimal focus.
• Threading: M48 threads, compatible with T-ring adapters for various DSLR cameras.
• Compatibility: Designed for Sky-Watcher ProED 80 and Evostar 80 ED APO refractors.
• Field Correction: Corrects edge-of-field distortion critical for wide-field astrophotography.

This accessory is perfect for enthusiastic astrophotographers who aim to broaden their imaging capabilities without compromising on optical quality. By increasing the telescope’s speed and flatness of field, it allows for clearer and faster celestial imaging, enhancing your ability to capture deep sky objects with improved sharpness.

In conclusion, the Skywatcher ED80 Focal Reducer 0.85x is a vital tool for amateur astronomers dedicated to astrophotography. Its capability to lower focal ratio and correct edge distortions significantly boosts the versatility of the Sky-Watcher ED80 refractors.
