Venus rotation

Hi guys,

For the first time in years I was able to capture a planet over 4
consecutive evenings!
This allowed me a complete mapping of Venus because of its 4 days high
clouds spinning period.




On April 19th I captured venusian clouds among terrestrial clouds which
did let me have a thin minute of clear sky only. Seeing was fairly good
nonetheless, hence my frustration.

On April 20 and 21 I had clear sky but poor seeing.

On April 22nd I decided to move my telescope over a beach (!) to prevent
convective heat from the ground. Venus was well placed over the
relatively cool sea surface (18°) and I could enjoy a breathtaking image
at the eyepiece!
The 2 bright cusps were easy and prominent without any filter and I
could grab my best Venus shot ever.
Need an house in front of the sea…
