TDS6725 This star is listed as a Tycho double star in the WDS catalog, with a
separation of 600 mas and equal brightness. However, it appears
entirely single in our AstraLux data. Although we cannot strictly rule
out that the companion is presently too close to be resolved with
AstraLux (e.g. due to a close to edge-on orbit and unfortunate timing
of the observation), we consider it relevant to regard the possible
companion as unconfirmed at present. Jnn2012
