Here's a composite of two exposures taken at 2 minutes to 9 this evening. A 1 second exposure for Mars combined with a 1/320th second exposure for the moon, both at f11. I had to zoom out to 120mm to get both in the frame...
If you click on the image again to bring up the full size image you can see that, even resized down to 1600 pixels wide, Mars is showing a disc.
