That is amazing. I'm just getting into astrophotography and I've only so-far taken panoramas of the moon at various phases (I've got 5 nights' worth ... need at least another 7) with our school's 16" 'scope. I'm completely unfamiliar with your technique of taking hundreds of frames in a brief period; why do you use that, what are the advantages?
