129 au may be an impressive separation for a brown dwarf binary, but it's kind of 'middle of the road' for brighter stars - including M dwarfs.

The name of the object, CWISE J014611.20-050850.0AB gives the coordinates in RA 014611.20 and Dec -050850.0 IIRC.

What's the format? Seconds, or hours, minutes and seconds?
That is, is it in Eridanus (above Fornax), or in Cetus, nearer to Baten Kaitos?

Thanks. So it's somewhere closer to Baten Kaitos (01h 51m 27.63, −10° 20′ 06.13).
And I learned something new again. This time, the notation.

So if you want to hunt this down with your IR sensitive camera you need to apply a correction for precession from the year 2000 position to the present date. :)
