Nova V1710 Scorpii, 19th April 2021 - image and spectrum

Here's an image and spectrum of the nova in Scorpius (S&T article here). Pretty happy with how this came out, and I managed to keep the nova's spectrum off the background stars too. The hydrogen alpha emission is so strong I had to use a log scale for the spectrum (which was extracted off a linear image). H-beta is also prominent, not sure what teh otehr peaks may be. 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.
