A longer exposure (or stacked exposure) will help the SNR.
The spectral shape looks odd???
Increase to distance between the grating and the chip will give better resolution.
What do you think?

So the second dip is H beta (4861A)? That's what I told vspec and was getting 4.7-ish A/pixel. Might have to re-visit how I'm mounting the Star Analyser or try it in my scope perhaps?
Thanks for trying my file, sorry it's so odd.
