Ray, I was asking the same question: Has Betelgeuse come closer to Bellatrix? But I couldn't be sure -- never been very good at star mags.
Photos: is it better to defocus the camera?
Another question that came to my mind is: what if Ptolomeus et. al. observed Betelgeuse when it was having a positive change when they called it Alpha Orionis? Comparing it to Rigel now is frightening!

Assunto: [AstroLeeds] Betelgeuse fainter?
Between clouds last night - and with a very bright Moon - it seemed to me that Betelgeuse had faded somewhat more.
Does anyone have an opinion?
Time to keep the camera handy for some short exposures, really.
