CCDS Acquisition Camera User’s Manual J. Marshall 05 August 2005 Background: The CCDS acquisition (slitviewer) camera was replaced in August 2005. This modern CCD camera is much more sensitive than the old system! It should also be easier to use. The new acquisition camera is a SBIG ST-9 CCD camera.

CCDS Acquisition Camera User’s Manual 6 3. Normal Acquisition Operation Once a link is established with the camera and the temperature regulation is turned on, you are ready to use the system. Under most circumstances you will want to use the “Focus” mode of the camera.
CCDS Acquisition Camera User’s Manual 7 You may also use the “Grab” button on the toolbar. This will take only one image instead of a continuous sequence of images. This may be useful if you want to take an image of your object’s position on the slit for reference on a future night.
CCDS Acquisition Camera User’s Manual 8 Exposure time guide: For very bright objects (V<8 mag), minimum exposure times of 0.12 seconds are plenty long; in fact, the object will most likely be saturated. Very faint objects (V>19 mag) are detected easily on a clear moonless night in 5 seconds in unbinned (high-res) mode.
CCDS Acquisition Camera User’s Manual 9 To place a filter in the beam, find the “Filter” pull-down menu and simply select the filter you desire. The camera will rotate the correct filter in front of the CCD. If for some reason the items on the pull-down menu are greyed out, select Filter Wheel Setup.
CCDS Acquisition Camera User’s Manual 10 One exception to this is that on clear, moonless nights it may be difficult to see the slit for short exposure times.
