Nice report Ted.

By companion to Antares, did you mean M4 or NGC6121? I found the later using my little 6" dob at a dark sky site last Saturday for the first time. Seeing and probably aperture prevented me from resolving any stars but it was fun to find and actually rather obvious once I got Antares out of the FOV.

Double star is what I meant. Antares has a hot blue companion star, Antares B magnitude 5.5, of spectral type B2.5 at a separation of about 2.9 arcseconds. It was a greenish tint always present at the same spot in the bright scintillation of Antares. Not a clean separation due to low magnification (38x) in an eight inch reflector along with the unsteady seeing and subsequent blurring of Antares.
