    Re: Moon 'sights' using Anti Spoof Pro - my numbers are a bit out

    Perhaps, Lance, this is because the Moon lower limb is not quite illuminated for the first two sights, and only slightly so for the remainder. The phase image on the attached Astron screenshot of the first sight shows this, together with a calculated Hs for this sight of 0.5' lower than your observation.

    PS - Love your location. Is Mr Wooby's in Salamanca Square still going?
