Wow Emil, that look overkill, no ? You really have to go that crazy with AP's ?

No, doesn't look overkill or crazy to me.

I found this works pretty well most of the time. I actually always use a scheme like this on Jupiter, and know of several others who use a similar scheme. Sometimes with smaller APs, sometimes with less and larger APs (noise blue channels). Sometimes I even add some extra small APs over shadows of a moon or on a moon itself , but I'm always sure that the feature is stable enough to handle that.

But most of the time something like this works well.

HI,Emil.
I know how to avoid this align problem just as you pointed. I say that because when I face this problem then mean I cant get a nice result from them. I found for a pic,for example, if size 100 AP will give best detail,when I use 100 cause problem(like this I post,usually only part of edge show problem),I will ignore them.
AS2 work quite well.I use it chose best video and later stack.Of course,if it can make a precise stack from bad seeing video,that not bad.
If you still want to get this video,I will send to you.I just got your post before I del it. unfortunately,the file large as usually.

This number of APs seems reasonable to me. In fact I was using ~75 APs until recently when Steve and Glenn pointed out that a smaller number might work better. In my testing 30 APs was never any worse than 75, and in above average seeing 30 was very slightly better. Not much, but if you looked close you could see the difference. So considering that it runs faster to boot, I'll be sticking with ~30 for Jupiter.
