Venus size at 50" arc-sec

Dear all,

Venus taken on 16-05-2020.

This might be the last 1 or 2 image before the Venus season ends,
as Venus is merging too close with the Sun during sunset.

Venus on 9 April 2020

Venus on 9 April 2020 is reducing its phase (now 41.7%) to become more crescent shape now, though the apparent diameter is bigger at 28 arc sec.

Cloud features are still not apparent in my present filter setup.
