And the planets when they're opposite the is always at 0 degree in the draconic chart tooIn a Draconic chart, 0Aries is defined to be the location of the Moon's North Node. That means a Draconic chart is effectively a different zodiac, since all planets are shifted by the same amount. Checking your Draconic chart is somewhat similar to comparing your tropical vs. sidereal zodiac charts.
A Draconic chart can be an interesting way to look at North Node and South Node evolutionary and growth issues. For example, a planet Square the Nodes will always be at either 0Can or 0Cap in the Draconic chart, which is one way those points have significance. For that reason, it may be better to just look at aspects between the planets and the Nodes, to see the relationships between them.
There are of course any number of other potential Draconic-like charts or alternate zodiacs one can think up and look at. For example, have 0Aries defined to be the location of Pluto instead, or have 0Aries be the North Node of Saturn instead of the Moon, etc.
