Ah ok... Well DSS is free but I haven't used it in a long time. I use CCD Stack now. Keep in mind that when using short FL lenses 50mm and down your stars are very undersampled so if your shot is noisy then it will be hard for any software to find stars for aligning. It'll pick only the very brightest ones.
Having said that when imaging at 50mm or 35/25mm it is very likely the subs won't need any registration because the motion between each sub is negligible. Unless you have field rotation but even then it's ok on 5 to 10min subs.
Is this the info you were after?
