BNK 11 EQ Cha. Koehler & Petr-Gotzens (2002) suspected duplicity but were Koh2002
unable to split the pair.
More commonly known as EQ Cha, this star appears single in the
AstraLux images, but has most likely been partially resolved as close
binary in previous imaging campaigns (Kohler & Petr-Gotzens 2002; Koh2002
Brandeker et al. 2006). With an angular separation as small as 40 mas Bnk2006
in 2003, it is fully plausible that the companion exists but was too
close to be resolved by AstraLux in 2010. Jnn2012
