Not quite the same camera I believe. I believe the QHY and the starshooter are very similar but both read the imaging CCD in a different manner. I don't know the full story but it may be in your better interest to contact Theo "Gama" on this site as he is the QHY dealer in Australia and he can fill you in on the different chip reading methods. Give him a call he won't mind.
