So... grabbed myself a Powermate 2.5x... went and had a quick go with it. Much bigger image.... actually a litte hard to centre and keep in the movie crop zone for long enough to get the 3,000 frames I like to get.
So, processed in AVIStack 2.0, captured using BackyardEOS on my Canon 60D... and without further ado, I present my very first go with the Powermate.....
