About this image

Phoebe is a rather bright satellite (V=16.6 at the time of observation) and so has been known since the 19th century. Pickering discovered it in 1899 - the first planetary satellite to be discovered by photography.

This image is rather artistic in my view. The Dilworth design of telescope uses several transfer lenses which, unfortunately, scatter a tiny amount of light. Normally it is quite unnoticeable but when something extremely bright, like Saturn, is just outside the field of view and the image is contrast-enhanced, this is one of the effects that can appear.
