What does it do?

You can load the Images and optionally some dark.frames (will be averaged and subtracted automatically if exist).
If there are some images you don’t want you can uncheck them.
Zooming into the images is done with the mouse-wheel
Optionally you can average some of the images to get a better signal to noise ratio for the sky-background or the foreground. This averaged image is brightend internally and at the end of the processing blended in “lighten”-mode into the resulting image

The resulting image can be saved in Jpeg,TIFF or BMP format

Another feature is the creation of a time-lapse movie as an “AVI”-file
Of course this feature can be used to create any time lapse movie, not only starmovies..
