Comparison of
CCD and Digital Cameras for Ha Imagery
Place your mouse
over the image below to see the difference between images taken with
a monochromatic CCD camera and a consumer digital camera. Moving the
mouse off and back again changes the image.
The CCD captures more of
the disk detail than the digital camera, even though it
has less pixels!
The higher resolution of the CCD produces a cleaner image.
