Conclusions

Integral field spectroscopy + LGSAO yields:

High spatial resolution tuned to coronal emission features

Distance determination: 3.85 ± 0.23 kpc

Direct measure of the inclination: 62 ± 1.5°

Study of the 3-D morphology of V723 Cas ejecta

Detection of inhomogeneous shell

Equatorial torus with polar globules in [Ca VIII] and most other emission features

Prolate spheroid in [Al IX]
