Last night was good. The nova is now in the mag 9s and generally a star of that magnitude is out of range for me spectroscopically. But because virtually all the visible light is coming from 3 narrow emission lines (and dominated by one, H-alpha), the spectrum was still easily gettable. Effectively, the low-res spectrum is one bright dot & two fainter ones!

The nova itself is now very red, in consequence of the dominance of the H-alpha emission.
