G'day Dennis,
You are correct. It is not Sirius B.
I've learnt something. Thanks.
Regards
Vincent

- Looking at the overall image scale, the distance between GSC 05949-2774 and Sirius is 5’ 27”, which is 327 arcsecs. Using this as a yardstick, I estimate that the distance between Sirius A (centroid) and your candidate star to be around 50 or 60 arcsecs? The published value is just over 8 arcsecs for the year 2008.
I could be wrong, and it would be nice if that were the case! I wonder if anyone else can shed any further light on this, or verify that I have N & E correctly oriented.
Cheers
