The weather didn’t cooperate last night so I have no new images of C/2019 Y4 (ATLAS). I’ve been playing with images taken over the last few nights using FITSwork and iterative Gaussian sharpening (thanks to Nick Haigh for putting me on to this). These images show the development of the inner coma region over three nights. The first two were taken with by camera in 1×1 bin mode. Unfortunately I don’t have this for the last night so I have used a resampled versin of my normal 2×2 bin mode. All use the same Gaussian sharpening params (r=4.13, 20 iterations, 100% strength). You can see the components separating as the move relative to one another.
