The SBIG STX-16803 CCD Camera will have a full frame image buffer for storing image data during download. The STX will be able to image during download process. Exploring the possibility of using this buffer for pre-processing pixel defects based on a defect map provided by the CCD manufacturer, at the user's direction.
As CCDs get larger, the tracking CCD is moved farther off-center from the optical axis. This can result in out-of-focus guide stars. In order to compensate for different telescopes and different tracking CCD locations, the built-in guider will have a small, user accessible, focus adjustment for the tracking CCD. Once this is set for a particular camera and scope combination, it will not be necessary to change it.
