Thanks Eric I shall report back on the 3x tv for sure.
Oh man! John are you saying i've wasted my time converting this very expensive fan crushing the leds like a man possessed cutting it down to size with a hot Stanley knife and duct taping onto the scope with expectations of Damian Peach standard images only to have my imaging bubble burst by talk of cyclonic tube currents!?!?

Vibration was my main concern though it seems pretty smooth. Oh well we shall see lol
Yep I went for the 3x tv over the 2.5x powermate because of its extendible magnification and if/when I part with my DFK the 5x powermate will be sent with it.
