Rob, please let us know if you would like any assistance with the process of taking reference star spectra so that your camera/lens spectral response can be calibrated.
Cheers,

Thanks Hamish! I observe from home on the outskirts of Bright usually but these were taken from Clearspot Lookout, my go-to when I need flatter horizons. The "calibration approximate" refers to my use of a DSLR & lens, where there are lens aberrations and no really effective way of ensuring that the target is always in exactly the same position and that the spectrum is always cast at exactly the same angle. I have lots of sharp clear star spectra for calibration - novae for example are very useful.
Look forward to seeing your spectrum!
