TRACK WHERE YOU WERE DOES NOT WORK
When using CCDSoft’s Self Guide, after pressing Track Where You Were, the system does not begin tracking (i.e. the Start Exposure With Imaging CCD never enables).
If the “Track Where You Were” never enters the tracking state, it probably means your mount has significant backlash or overshoot which is preventing the software from being able to put the guide star back to its original position. The criteria is to put the guide star back to within +/-0.5 pixel of the original guide star. This criteria is not too stringent, as it is the definition of “Track Where You Were”. Look into eliminating backlash/overshoot and or Interrupting “Track Where You Were” and trying it again. Also, you might try setting your aggressiveness to a smaller value or making your calibration correction speeds slightly higher (if it is overshooting).
Another point worth mentioning is to use “Track Where You Were” and if it appears as though it is not going to be able to start tracking, merely “Interrupt” it and use “Track Where You Are”. You can then rely on the Use Previously Marked Centroids option in the RGB Combine box to align the images.
