Hi Lester

I should have read your first post more closely. When we are talking about sensitivity the mono and colour camera have the same Lx value. I what I should have said, and I hope I get this right, is spectral response. If you take your standard colour camera such as the TuCam, the CCD has a RGB filter (Bayer Filter) incorporated into the chip. This mean that each pixel of a 640X480 chip will have its on individual colour filter. It works out that 1/3 of the chip is red, 1/3 is green and 1/3 is blue.

While a colour camera is great you are losing information. I have a USB 2 Lumenera colour camera and while it takes great images of the planets there are limitations. From what I have seen of Damian Peaches work with the monochrome version of the Lumenera there is a definite advantage it using RGB filters (refer back to my first post)

Bye for now got go and watch CSI
