Pentax q7 modification

If RGB filter is removed from imx144cqj what will be the wavelength range and relative QE curve ?

I believe that the wavelength will range somewhere between 468 - 492 hz. As to the relative QE curve it will depend on conversion factors but it will be nearly flat until x axis nears the higher end of wavelength. Then you may see a slight bump in R value. It will certainly not make the sensor quite black and white only.

Sorry ... spectral range in nm

Modification for astrophotography.

So roughly the B above middle C then.

A little background, please? What is this magical file that can seemingly change what a Q7 can see?
