Color camera will be less sensitive than a mono, backing onto a f11 scope is a big ask for a guide camera, usually one tries to guide with a small fast scope..... Ie I use a 88 mm megrez at f5.6 with 1-2 sec updates. Away from the galactic plane also makes it harder to find nice guidestars.
As for the image, nicely centered, and it seems to be tracked well enough, bit more saturation would be aesthetically more pleasing.
