RC Astro MTF Analyser

Just seen this on the RC Astro site.

It seems to be a calculator for assessing the effectiveness of camera to telescope combinations.  Rather technical for me but looks like it is along the same lines as the Astronomy Tools CCD Suitability calculator but appears to give different results.  Any  thoughts?

It is a bit more serious than Astronomy Tools CCD Suitability calculator, but still flawed in my view.

1. Effect of mount tracking / guiding precision is not taken into account

2. Effect of pixel blur on final FWHM is exaggerated (it has very minor effect that can be demonstrated easily)

3. Under/over sampling is improperly reported
