You can load a reference image of the object you want to capture to adjust the position of the telescope and the rotation of the camera. This is very useful to continue a sequence over many night.

You can adjust the display threshold and the color of the reference image in the preview options.
Normally you want the threshold to display only the stars from the reference image.

To load the image use the menu File / Open reference image
