MiniSHG and Ha 7nm filter

The attached screen shot shows a few things:
1. The Baader 7nm Ha filter actually has peak transmission at 6580A.
2. The movements in the solar surface are clearly seen as "wiggles" in all the absorption lines.

The measured resolution R=33529 and the dispersion 0.0635 A/pixel match up pretty well with the SimSpec for the MiniSHG.
