The Ghosting Problem<br />
Residual Bulk <strong>Images</strong> (RBI):<br />
occur when l<strong>on</strong>g wavelength<br />
phot<strong>on</strong>s (such as in the IR<br />
spectrum) penetrate deeply<br />
enough to produce residual<br />
charge which is then carried over<br />
to the next exposure.<br />
SRIs are similar to RBIs but mainly caused<br />
by oversaturati<strong>on</strong> <strong>of</strong> the chip.<br />
SOLUTION: Switch cameras!<br />
(SBIG ST-10XME)<br />
Also, set the aut<strong>of</strong>ocus<br />
procedure <strong>on</strong>to a dimmer star.
