Stacking two or more images with PI

[whiteLion]

Hello! I'm new in processing with PI and I have one question, if anybody can tell me how can I stack two or more frames from diffrent nights, diffrent conditions (at home and on mountain with very good seeing) and diffrent compositions!
thanks!

PS: hope this is not the wrong section

Did you have a look at the video tutorials, in particular those by Harry Page http://pixinsight.com/videos/index.html? Also, have a look at the BatchProcessing script discusses elsewere in this forum.
