    The video camera I use is rated at 0.0003 lux. Using that 50 mm F1.4 lens I can see stars down to
    around mag 9. Since the camera is sensitive to different frequencies of light, the spectral tyoe
    of star will effect what the faintest star can be seen. 
    
    I piggy-back my video camera to the scope, a skywatcher 70 mm refractor. If use the prime focus
    method, then the scope would act as a 900 mm F12 lens for the video camera. But then the feild of
    view is narrow, and I can't see as faint.
    
    So I use the piggy-back method. I use the video camera as a my way of star hopping.
