Wanderer Astro flat field mask 225mm V4 IR (85911)

A flat field mask produces a white area with consistent brightness. To use, place the mask over your telescope optics and photograph the illuminated surface. This flat field image reveals the exact brightness distribution of your optical system and allows you to correct any brightness gradients during astrophotography image processing.

For the most accurate results, use the mask under the same conditions and with the same optical setup as your main images. The mask is designed for mobile use and can be easily powered in the field.

LED technology ensures a truly white, color-free surface. The flicker-free lighting allows for even short exposure times.
