I decided to try the PST with my 5DmkII. It seems to capture the edge detail a bit better than the QHY5L-II but, while I quite like this image, I prefer the results from the QHY.
I also used it on the iOptron SkyTracker as I couldn't be bothered setting up the EQ6, and it worked really well! Very happy with the SkyTracker.
Bigger and better quality here:
