Cooling of the CCD to reduce dark current is unnecessary at the short exposure times common to planetary imaging and autoguiding, but there remains the possibility of bright pixels in an image that can raise the threshold of brightness required for the most sensitive guiding performance.
The ability to automatically take and subtract a dark frame results in a very smooth background against which detection of dim stars is more reliable. It takes a sequence of images, grading them for sharpness and keeps the sharpest one. Typically you would take short exposures, knowing that throughout the sequence a stable period of seeing will give a clear image. The Planet Master command beeps twice each time a sharper image is acquired.
The dialog also shows you the current sharpness and the best sharpness in terms of a Figure of Merit FOM. If the object is too bright even with the shortest exposures you may find placing an aperture mask over the telescope or using neutral density filters will get the brightness in range. The Grade Image By Sharpness command allows grading a set of already acquired images. Many planetary imagers like to average several of their best exposures.
This requires taking a large number of images in a short time and then examining each image for the best of the lot of the best few of the lot. In this case the imager might prefer to use the Autograb function of CCDOPS to capture as many images in as short a period of time as possible. Planets rotate! PlanetMaster software may then be used to automatically examine a series of images and assign a Figure of Merit for sharpness to each one.
Then only the best of the lot can be selected for averaging. Keeping your drivers up to date is the best way to ensure your camera runs smoothly, so remember to update your drivers regularly.

You might want to review the other changes made in the Readme File which is also included in the archive. ST-4 users should download CCD. ZIP [ver 2. This program allows you to load two ST-4 images and blink them in rapid succession to easily see if any object in the field of view has moved between the frames.
ZIP updated to version 2. This program transfers all of the autoguide functions of the ST-4 to a remote computer up to feet away from the ST-4 control box. CCDTRACK also offers a number of features not available with the ST-4 in stand alone mode such as text and graphic displays showing the tracking accuracy in real time during the guiding session and the accumulated error of the guide star image.
