If you try stacking a few frames, you will get rid of some of the noise (for example, the jaggedness around the edge of the solar disk and the very bright regions). But make sure that you get the full disk in all the frames you stack. And the stacking program typically requires all the frames to have the same dimensions. Stacking even 5 frames will improve the noise a lot, because the typical noise is uncorrelated from frame to frame. Then you can use a sharpening program more effectively.

In my opinion, the best camera for this kind of imaging is the 178MM. Smaller pixels and larger sensor. It's available at a good price these days.
