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]
