An estimate from the RGB image is somewhere near or a little below mag 10.5 for the nova as at 19th April. I presume there may be a good place to submit this data if it's useful to observers, not sure where?

Equipment: C14 at f/7, Atik 460EX, SA100 grating. ZWO RGB filters.
Hi Andy. Well done with the SA100.
I took a spectra a few nights later and have attached it with a few labels. Some of the other lines a Fe lines.
