I have a Wollensak 14" f10 Process Raptar in Alphax shutter, and a Wollensak 14" f10 Apochromatic Raptar in Alphax shutter. They look similar, but not "exactly" the same, but pretty close. I wonder if there is a difference in their design? I wonder if this was just a name change over time? Both are coated optics.
