Before yesterday I did another experiment with the 600/mm by taking automatically Ne/Ar per exposure, finally I just did "Wavelength Registration" so used only the 1st of them - still saw the skew of lines at higher magnification (1-2A) that Wav.Reg. feature removes - but question then which of my per-exposure calibrations was correct.
So here is the basic result (this time 5 min x 29 frames), all processed by ISIS, using only 1st cal.frame:
(LHires 600/mm, 15 um slit, ATIK 414 EXm, R~3000 - 2500 in the end, Helioc. corrected)
At least caught a bigger outflow at H-beta, with tons of other lines varying.
The blue peak of Hb was down comparing to previous day.
Cheers,
