Description:

naked eye grouping.  It is at  7hr 24min and -32 12.

Col 140 is a very large open cluster I have called The Tuft in the
tail of the dog. There is a naked eye fuzzy spot at the end of the
tail of Canis Major.  I have found it to be an excellent area with
the binoculars.  It includes a wide double, Dunlop 47, which is 5.3
and 7 mag, sep 99 ", which I see as blue and light yellow in the
telescope at 100X.
