I'm blessed with first Florida winter vacation over the Christmas holidsays. A real relief from Woodstock's 16F temps right now. I have shot many moon-sun lunars but never a moon-star one.
I took advantage of clear, very dark sky, mid-60F temps and Frank's convenient GPS Anti-Spoof app with PAUSE feature to shoot my first star lunars from central Florida. Aldebaran-Moon (far) shots were super easy and results better than I deserved. My best shot of eight was this one.
Dec 24th, 2017 GMT 00:05:54 Moon's age was 5.7 days, a waxing crescent.
