Hi, Daniel. Sorry for this late reply -- I've been reading but been busy too with work.
I just wanted to say I actually take a minimum of 5 shots up to a maximum of 9. I haven't tried 10 but I'm suspecting misalignments might start cropping up.
I, too, have difficulty with taking good indoor shots. I thought I was doing pretty well until I saw my wife's low-light indoor shots this past weekend. They're less blurry than mine. It could be the camera but I think it takes practice to get good indoor shots.
