Is it just me or does the separation of the two brighter stars in Acrux seem smaller in the past 12 months? Now I realise that they are revolving around each other but I didnt think I would notice with them closing on each other in 1 year through the eyepiece. I am sure it's not my imagination nor poor collimation as I notice it through my SCT as well.

Anyone else agree with this or am I just going nuts?
