Finally, a night just about suitable for some observing! In preparation for the November main item, I wanted to sketch this double, a nice easy to find pair, the primary star was a cream yellow, about right for a K type star. The Secondary was white to blue white, which matches the newer spectral class of A2Ia+ found in stellarium, The WDC has it as an F7V as found in the Skymap info (I used that for the notes on the image, too late to correct it now!) This is an actual binary pair.
In a previous observation on 18 Jun 2000 I recorded the secondary as slightly greenish.
This time there was a first quarter moon not far away, but in 2000 there was a full moon, but very low down in Sagittarius, so it would have been less of an influence.
