Some very nice detail coming in now Mark.
The easiest way is to take two exposures, one for the disc and crank up the gama and gain for the proms. With the DMK51 I use around 150 gama and have the gain at least double and increase untill the solar edge is starting to wash out. It may be close for your DMK41.
As for processing have a good look at these tutorials.
