The first version 0.9.9 with internal star alignment is ready and can be downloaded for testing.

Star alignment:
This option allows stacking without any external program. It is not suitable for mosaics. No settings, fully automatics alignment for shift in x, y, flipped or any rotation using the stars in the image.

The program combines four close stars into a pyramid and compares the six pyramid dimensions with pyramids of the first/reference image. It selects at least the six best matches and uses the center position of the pyramids in a least square fitting routine for alignment.
