thank you guys for your reply. The "kundig" chart shows the grades where transit planets make aspects on a considered chart. I.e, I have moon on 5 libra and venus on five aries, on the kundig chart on 5 sagittarius is marked a trine with venus and and a sextile with moon... the kundig chart shows which grades of the zodiac are involved in aspects with the considered chart. I hope I have made my self clear, anyway you can log in in on the astro.com and on the extended chart section choose kundig chart so you can understand what I mean. I think it's a powerful instrument, but of course PD is great even without that! :-)
