Removed the front element on the Grandagon-N 115. Cleaned gently and well. This is an interesting element. Very thick at the edges, and ground in such a way that it is quite thin at the center.. So the light enters the glass and reflects from the sides back into the glass, creating the effect of a haze. I'm sure there must be a good reason that it is not painted, and shall remain so. Some black paint degradation along the bottom. Will have to research what may be a good material to repaint this area. It would have to be very thin. Perhaps a marker, or thin hobby paint.
