Dimmer Saturn – 12.8° to the upper right of the Jovian Giant – is nearly 15° up in the southeast.  In the starfield, Jupiter is passing Deneb Algiedi (δ Cap on the chart).  The gap is 2.1°.  Saturn is the same distance to the upper left of Theta Capricorni (θ Cap).  Use a binocular to locate the dimmer starry background.
