  Just 10 recurrent novae (RNe) - which erupt repeatedly on timescales shorter
than one century - are known in our Galaxy. The most extreme RN known (located
in the Andromeda galaxy), M31N 2008-12a, undergoes a nova eruption every year,
and is surrounded by a vast nova "super-remnant", 134 pc in extent. Simulations
predict that all RNe should be surrounded by similar vast shells, but previous
searches have failed to detect them. KT Eri has recently been suggested to be a
RN, and we have used the Condor Array Telescope to image its environs through
multiple narrowband filters. We report the existence of a large ($\sim$ 50 pc
diameter), H$\,\alpha$-bright shell centered on KT Eri, exactly as predicted.
This strongly supports the claim that KT Eri is the 11th Galactic recurrent
nova, and only the second nova known to be surrounded by a super-remnant. SALT
spectra of the super-remnant demonstrate that its velocity width is consistent
with that of M31-2008-12a.
