You have to think about what you want to do with this scope. Given that you only have a D40, I assume you are more leaning towards visual observation? If this is the case, you will benefit little from the features of the HD.
To be completely honest, I do not quite understand the motives behind a flat field modification for these SCT expect when used on very high ends mounts with top notch equipment and aimed at small and faint objects (some planetary nebulas). A 3500mm focal length instrument is just extremely difficult to use in Deep Sky AP. Planetary no problem, but deep sky? You'd need a C8 or more to do a decent autoguiding on this! Especially since there is no focal reducer at this stage!
So besides planetary, deep sky AP with this tube means super heavy duty mount, and super accurate autoguiding, and that usually comes together with a nice dedicated CCD to make the most out of your package.
Sorry Bart, I don't thinks this is helping much, maybe you should try to explain what your priorities are, under which sky you will be observing etc.

Sylvain,
So you think the CGE 1400 EdgeHD isn't suited for deep sky viewing or deep sky AP? Or are you telling me the D40 is a bad camera for deep sky imaging?
Clear skies
