It might be expected to have shown Beta Cen double if the separation was no less than at present. I don't know if Innes checked Beta Cen with this telescope. For the present day observer, the new measure of Beta Cen explains why it has been so difficult to separate recently. I've tried and failed with 6 and 7-inch scopes at various times, and in recent weeks not found a steady enough night for trying with the C14 at Downer. This suggests telescopes of less than 30cm aperture are unlikely to show the pair even under excellent seeing conditions - and that larger scopes even on steady nights would have a better chance with a neutral density filter, as Hartung suggests.
Any successful observations are welcome.
