Comparing FWHM isn't all that useful, your local seeing conditions impact on FWHM. More often than not, your seeing conditions will be a lot worse than the resolution provided by your telescope... Also longer focal length scopes will almost always give higher FWHM's than a short F/L system given identical seeing conditions... Just an observation I've made when testing two different optical systems side by side..
Don't take it the wrong way mate.. I'm more a newtonian fan than an RC fan... And agree with much of what you and Mark have said, Its just your method of proving your point seems flawed to me.
Fact of the matter is you're comparing two very different optical systems, in different seeing, with different mounts, different cameras... Trying to get an idea of which scope produces better star images. There is no standardization in your comparisons, so they aren't definitive proof of either systems superiority..
Both optical systems are producing great images for their owners... That should be good enough for everyone..
