I will describe how spectroscopic monitoring from the Global Jet Watch observatories solar of the Galactic microquasar SS433 elucidates the mass-loss via its accretion disc, circumbinary disc and jets and show evidence of how these are evolving, and of how they are coupled when the microquasar goes into flare. I will also present a succession of spectra of a Galactic nova (V5668 Sgr) which illuminate its evolution in dust production and metallicity measured since shortly after detonation in March 2015 up to the present.
