Yes, P-P maps the zenith and nadir of eqrs rather badly, and this image shows it at its worst. I'll fix this as soon as I can work out the best way.

(PS. how do you attach an image in this forum?)

For example here is a Panini-Pro planetoid of a small dinner-table pano -- actually the first one I have succeeded in making, and not very good either. The glitches around the nadir are visible but in this case not obtrusive.
