PegasusAstro flat field mask FlatMaster 120 Neo (88334)
PegasusAstro flat field mask FlatMaster 120 Neo (88334)
480.59 $
Tax included
A flat field mask produces an evenly illuminated white surface with controlled brightness. By placing the mask over the telescope optics and capturing an image of this illuminated surface, you create a flat field frame. This flat field image reveals the exact brightness distribution of your optical system and allows you to correct gradients, vignetting, and dust shadows during image processing. For best results, the mask should be used under the same conditions and with the same optical setup as your actual imaging session. The device is designed for portable use and can be powered accordingly.
