worlds of Uranus and Neptune are difficult planets to image at the best of times since
they present very small angular disc sizes. Using larger instruments and more
sophisticated imaging tools, other amateurs have managed to obtain some extraordinarily
good portraits of these worlds including some of the faint moons. The images below were
taken using a 10 inch (250mm) reflector and GSTAR-EX video camera from suburban Sydney.
The respective discs of the planets are purposely over-exposed to reveal the remote and
rather faint moons.
Above: Composite RGB image of Uranus combined with
2.6 second integrated exposure of the moons Oberon,Ariel, Umbriel and Titania. The
over-exposed Uranus in the long exposure was subtracted during processing. The RGB
version was then added.
