Trying to solve a focus-shift-with-altitude issue, we took this ultra-short live sports action photo of the inner 4.5 minutes of arc of 47 Tucanae. Has anyone ever noticed the extremely blue star toward 5 o'clock? It was there two weekends in a row, so probably not our first supernova.
L 4x60sec, RGB 2x180sec each. Aspen CG16M on 20" PlaneWave. North up. Full moon.
(You've seen 47 Tucanae before, but the
whole shot is here.
