William Optics Flat6A III Special Edition FLT91(73852)

10718.17 Kč

Tax included

A field flattener is a lens that corrects the natural field curvature created by a telescope's primary optics. Without this correction, stars near the edge of your image may appear less sharp. The flattener is placed between the telescope and the camera, allowing astrophotographers to capture images with consistently sharp stars across the entire field. This particular field flattener is specially designed for the William Optics Fluorostar FLT 91.
