Not true, a mallincam works just fine on an ED80 in full colour, often with just a few seconds integration time, smear free.
It is about the speed of the scope, not the size of the glass. The mallincam is relatively low resolution anyway (720x576 or something like that) so you don't need the extra resolution that big glass brings. You do need speed though, F6.3 or better is the way to go, using a reducer to get you down under F5 makes integration times really fast, that is why they are also popular with hyperstar setups as you get down to F1.9
But on a bog standard ED80, you get full colour, check out the Night Skies Network to see the results.
