After a brief bit of joy the other night I discovered that I had entered
the ROC as the Fl in oslo, and then doubled that number for the ROC. So my
stunning f/2 camera was actually f/4, might as well buy a refractor type
lens and avoid the curved film surface. In the mean time I have plugged
away with olso and have the following. 130mm apeture, 150mm mirror, ~300mm
fl. The spot diagram shows some energy outside the airey disk in an almost
cardiod pattern.
Most of the results can be seen at

Any suggestions or is the design close enough to start the build and clean
up with testing during figuring?
