including the maximum value, minimum value, average value, and mean square
deviation, where the peak indicates the maxiumum brightness of the image. Using
the AUTO button you can perform an automated stretch operation to display the
image correctly before processing and using the plus symbol you can enlarge the
graph for finer adjustment of the image. It is recommended to keep "Automatic" on.

Plate Solve
Press the Plate Solve button to analyze the current displayed image to determine the
center coordinates (Right Ascension and Declination) of the image ‒ which shows
your current mount pointing position. You can use this to calibrate the mount by
pressing the "Sync to Mount" option in the pop-up box when the plate solve is
complete.
