Wanderer Astro flat field mask 100mm V4 IR (85907)

A flat field mask produces a white area with uniform brightness. To use it, simply place the mask on the front of your telescope and photograph the illuminated white field. This flat field image reveals the precise brightness distribution of your optical system, allowing you to correct for any brightness gradients in your astrophotographs during processing.

For best results, use the mask under the same conditions and with the same optics as your main images. The design is ideal for portable use and can be easily powered in the field.

LED technology ensures the surface is truly white, free from color casts. The steady, flicker-free illumination makes it suitable even for short exposure times.
