This eyepiece has been specially designed to provide a wide field image. This means that the image formed in the eyepiece will cover a wider field of view than usual and also the image formed will be larger in size, making it easier to take projection photographs through the eyepiece. Many Digiscoping enthusiasts take their high magnification photographs using this technique, and the KOWA 45x eyepiece (TSE-9WD) is perfect for this application. Thanks to the size of the image formed in the eyepiece there will be no vignetting problems even if the image formed in the eyepiece is already at high magnification.
