Hi Neil.
Good to hear from you.
Unfortunately, the image using a one-shot colour camera will not be as good as a mono camera.
A one-shot colour camera has a Bayer Matrix built into the front of the chip.
These are green, blue and red filters over each pixel, to produce a colour image.
As the Quark is monochrome in Ha, down the red end of the spectrum, the camera is less sensitive than a mono as the blue and green pixels will not receive anything.
The best result will probably in white light, where a much broader range of wavelengths will be captured.
But, I say, give it all a go. You just don’t know what you’ll get unless you try.
Whether you capture in colour or monochrome, the colour can always be adjusted later to match your preference.
I hope that helps.
Dave

Many thank
Neil
