I combined the unbinned RGB frames into an L frame. One this frame I ran maximum entropy, followed by a mild unsharp mask. I then used a DDP filter with a low threshold and filter. Then I combined the LRGB frames together in AstroArt 3.0. Finally I used PhotoShop to adjust the levels.
This compares nicely to the M13 wideshot in Sky&Telescope, July 2003 pg 117. You can even see the 16 magnitude galaxy IC4617 just barely.
