Here below we discuss in some details the impact that a large field camera, mounted to the direct focus of LBT, would have on the study of extragalactic novae. Particularly concerning Nova theory and Novae as distance indicators.
Nova outbursts are the result of strong thermonuclear runaways on the surface of a white dwarf accreting H-rich material from a low mass sequence star companion. The signature of such a violent event, at least for novae in the Milky Way, is the ejection of a shell, normally observable in H+[N II] and/or O [III] light.
