NGC 1605 is not a binary cluster
  The open star cluster NGC 1605 has recently been reported to in fact consist
of two clusters (one intermediate-aged and one old) that merged via a flyby
capture. Here we show that Gaia data do not support this scenario. We also
report the serendipitous discovery of a new open cluster, Can Batll\'o 1, with
a similar age and distance.
