  While fully automated methods for detecting faint moving objects in
astronomical images - such as Kuiper belt objects (KBOs) - are constantly
improving, visual detection still has a role to play especially when the fixed
background is cluttered with stars. Color intensity projections (CIPs) using
hue cycling - which combines a sequence of greyscale images into a single color
image - aids in the visual detection of moving objects by highlighting them
using color in an intuitive way. To demonstrate the usefulness of CIPs in
detecting faint moving objects a sequence of 16 images from the SuprimeCam
camera of the Subaru telescope were combined into a CIPs image. As well has
making even faint moving objects easier to visually detect against a cluttered
background, CCD artefacts were also more easily recognisable. The new Hyper
SuprimeCam for the Subaru telescope - which will allow many short exposure
images to be acquired with little dead time between images - should provide
ideal data for use with the CIPs algorithm. In addition, the current search for
KBOs to be targeted by the New Horizon's spacecraft after its flyby of Pluto
provides an excellent test case for the state of the art in faint moving object
detection against a cluttered background.
