As I was looking how to optimize the stacking of frames from .AVI movies I retried the free software RegiStax6. Last time the use was too difficult for me but today i found some more time to practice.
The result below is a shot from the moon on Jan 17th, 2016 taken with camere ASI224MC on Dobson Orion XT12. The result was finished using CS4.
