Thanks to the amazing hard work of Alex, the Magic Lantern developer and putting up with my millions of questions, my first decent holy grail without flicker.
This used Magic Lantern as the bulb ramper, and the post-processing python script that Alex wrote to remove flicker after all the images were shot. It's an amazing result compared to the flicker that this had before running it through the script.
