Hi Ric
I’ve occasionally noticed that the plotted positions of the same star, when associated with difference reference designations, varies slightly when I toggle between the two designations in The Sky 6 Pro when zoomed in.
If I activate the UCAC label, the star appears in one position at a certain magnitude but if I then switch to the USNO A2.0 label, sometimes the star “moves” and the magnitude may also change, albeit very slightly.
Cheers
Dennis
