See my post following yours. I should add that the Hubble CCD sensors have natively wideband response and very fine resolution.

Making a color-sensitive CCD array, or set of arrays, would not be the best available use of the total sensor area; making it wideband (infrared to ultraviolet) yields the best tradeoff between high resolution and high sensitivity. This is especially true considering that they want to observe a greater variety of wavelengths than any traditional color imager could provide.

Instead, they make the whole array sensitive to one strategic wavelength (actually a narrow band of wavelengths) at a time by putting one of several available filters over it. Some of these wavelengths are in the visible range, and some are outside.

Cause I sent similar photo’s around before and was corrected. See post 24.

I wish it would look like the photo’s however.
