Thanks Jeremy

I use a combination of the fully zoomed live view and the bahtinov mask which seems to work as I have an articulated DSLR screen but I would like to try a larger monitor and software analysis .

I know it is mainly photography but funny what you find when not looking

Just as Ray, I am using this (https://www.thingiverse.com/thing:1376415), in combination with Bahtinov and zoom (with 60D).
With 450D, it is one of those (http://www.iceinspace.com.au/forum/showthread.php?t=145306&highlight=small+things).
