Mike,
Keep in mind though that for imaging Mercury during the day time you need to keep your scope out of the Sun because of heating issues. The best place is one that has a flat obstruction to the east of about 15 to 20 degrees high. This way you can image Mercury at around 35 degrees altitude while still sitting in the shade.
On another note, I'll increase the gamma of the colour image tonight, it's a bit hard to see the fainter bits
Cheers,
