Paterson Grain Focuser

An inexpensive grain focuser from Paterson. 8x magnification is sufficient for focusing most enlargements. The image is bright and clear and you can still tell what you're looking at. With the 20x grain focusers you can see the grain better, but often not exactly which part of the photo you're looking at. The grain focuser can be adjusted for use by those who need glasses, and has a built-in protective cap to protect the mirror, and a rubber cap for the eye piece.
