These old AP's pop up every now and then at very reasonable prices. A 5 inch scope at f/4 is a very appealing wide field scope. I looked through one about a year ago and saw a bit of color on mag 1 stars. I'm wondering how much refocusing I would have to do with each RBG filter to get a decent CCD color image.
I would appreciate Roland's comment on this early design.
