I should have said, 'Porrima would show nice first defraction rings and Airy discs'.
Two years ago a couple of us made two or three trips to the site a little below
Montebello
to test a new telescope, using Porrima as a target. Porrima was a little more open
giving me a nice clean split in my 155mm.
