Last night's exploration of the CaII - H8 region (R~5500 average, edges defocused a little):
The CaII doublet is very thin, and features weak (despite bright continuum: 3000 ADU).
Asymmetric peak is confirmable on H7 + CaII blend and perhaps H9.
Velocities are generally larger than H-alpha or He I:

H8 consists of a wide absorption, a central peak and a satellite peak.
Question how it is changing (appreciate to see more spectra by others just to learn, though no professional requested it).
