2 inch 0.8x Focal Reducer and Field Flattener for Refractor Telescopes

This 2-inch 0.8x focal reducer and field flattener is designed for refractor telescopes, especially the 80mm f/7 ED model. It reduces the telescope’s effective focal length by 20%, resulting in a brighter image and wider field of view for astrophotography. The built-in field flattener corrects field curvature, ensuring sharp, distortion-free stars across the entire image. Perfect for capturing detailed and bright photos of nebulae and star clusters with shorter exposure times, this optical accessory helps improve photo quality while maintaining a compact and lightweight design.

Key Features:

• 0.8x focal reducer shortens focal length for wider, brighter images

• Field flattener corrects image curvature and reduces edge distortion

• Multi-coated optics enhance light transmission and reduce reflections
