What software (akin to Registax) is best to stack stills?

Just to add to that - yes, Deep Sky Stacker does work with jpegs, and yes, I've used Rot 'n' Stack with some good results and also some very "interesting" results - it's certainly worth a try!

Wow, Deep Sky Stacker seems to get a majority vote from the few replies given. Those of you who have DSS, have you tried Registax as well? And if so, why give the vote to DSS? I know somethings are subjective e.g. an easier to ue CP, or features, but if the net result can still be the same, I am looking for the quirkes that make the suggested programme that little bit more advantageous.

I use registax for planetary work and it is great for that. Registax does not derotate the images which makes it not a good choice for deepsky imaging.

A typical avi lasts 3 minutes only typically through a barlow lense whereas a deepsky imaging run could be hours long with a wide field or focal reducer. This means that the ability to derotate the images will be absolutely essential if you are imaging with a fork mount or in altaz for deep sky and not so important for planetary.

Of course if your perfectly polar alligned this will not be so important.

I guess it is just horses for courses really.
