Cleaning The Ccd And The Window - SBIG STX Series Operating Manual

Cleaning the CCD and the Window

The design of SBIG cameras allows for cleaning of the CCD. The optical heads are not
evacuated and are quite easy to open and clean. When opening the CCD chamber, one should be
very careful not to damage the structures contained inside. To open the CCD Chamber, remove
the six screws that hold the 5 inch front cover in place. Remove the six screws and lift the front
cover, exposing the structures inside. There is a rubber O-Ring that sets in the groove on the top
of the Chamber housing. The CCD array is protected by a thin cover glass that can be cleaned
with Q-Tips and Isopropyl Alcohol. Do not get alcohol on the shutter. Dust on the CCD should
be blown off. Use alcohol only if necessary. The optical window of the chamber housing can be
cleaned the same way. When reinstalling the chamber housing, be very careful to make sure the
O-ring is in the groove when seated.
