I tried to post a little earlier but the site was offline or something.

There is a list of 110 Southern Doubles in the Projects and Articles section, of all manner of separations and magnitudes for you to have a look at over the year, if so disposed.

Was interested in your observations with the 8" GSO CC. The 0.6 " separation would suggest that the scope would be struggling to split them but maybe an elongated Airy disc is possible. I remember a few years ago trying to separate Gamma Circinus, h4757, mag 5.0, 5.7 , sep 0.8" with my then 8" newt / dob and just being able to detect an elongated Airy disc .
