Got some spectra for this interesting symbiotic star in Ha, Hb (25Feb18), & CaK (26Feb18):
This is a kinda dim object (Probably <9.2 magnitude) for the LhiresIII with the 2400 l/mm grating, so I applied a low-pass Gaussian filter for the spectra charts above; did
not apply it to the calibrated spectra. I used the nearby star HD085235 for my image response curve (IRC). The CaK band was especially difficult so I had to go over
3 hrs to exposure this with the 43 Cm aperture reflector working at a little over F/10. As usual, any elemental spectral lines besides the Balmer bands are speculative.

Re: TX CVn
Here is the latest spectrum of TX CVn in H-Alpha (HD085235 was used as the instrumental calibration star):
Note sure if there is much change from the earlier one taken in February of this year.

Re: TX CVn
Here is a low resolution (LISA) spectra of TX CVn:
Conditions were poor, but I was able to use HD085235 as a reference star for the instrument response. After installing a new (used) Atik 460ex, I had to re-tune
the LISA to make the Ar-Ne sharp and placed in the FOV as indicated in the LISA set-up instructions (Ha at x=1981). Hope to take some more images
when the weather clears.
