Apart from the cost, astro CCD's need a computer for image acquisition and really need an observatory to be fully utilised. My main interest in astronomy is imaging comets where I may need to take the scope where I would not want to take a CCD. Bog standard DSLR's are somewhat comet friendly also. If exposures are kept short and fast optical systems used, the noise can be somewhat avoided. For that reason I will be staying with using DSLR's, though I will pine for a CCD for other deep sky lol.
