GDAY squintz.
I have aip4win and just got the upgrade notice the other day and havent done it yet, but i did find deep sky stacker a better program for stacking, personally i use median most of the time to stack, others have their favorites but this will remove the satelites if you want.
do you have any guiding capability? if not you will find this will severely limit future harder targets like galaxies and such, as tracking will deteriorate over time.
Finally well done on your very first image for this department.
