Thanks for checking on this Steve.

You are correct in that the star in NGC 6193 is also listed as HR 6187. Not sure but this may be one designation for the whole system.
My reference to H 4876 comes originally from Burnhams which I used on the original observation 21 years ago. In fact I now use
http://stelledoppie.goaction.it/index2.php?section=1 to check out doubles and looked it up under this number (4876) and it came up with the 6193 system, particularly labelling AD and AE components under this designation. I did not see the D component with the 132mm, but can see it easily with the 18", but then again this scope does not show the close B component!

All up this is a delightful system to study, with three stars around 10" or less separation from the primary, + the close component at 1.7"
