Here is the report of venus of the 9th july performed with the 130mm Cassegrain.

Good images were met during the session.

Poles were there but of more tiny sizes, both.

Banding pattern was clearly captured.

After one full rotation and one day more, please compare with the 04th obserservation (also the 3rd). banding pattern is similar but with different CM2 ( CM2 difference 74° and 8° sun longtude difference). Just noted (data collected from winjupos).

Thanks Tom and gents for their likes.


Here is the 10th july report of venus performed with the 130mm Cassegrain Under average good images.

Brightenesses are mentionned on the sketches.

The pattern was becoming quite different after a quarter planet rotation.
A 8th picture is needed for a conclusion.

Stanislas-Jean.

Here is the venus report of 16th July performed with the 130mm Cassegrain Under average good images.

Please compare with the12th images but performed on not optimum conditions, anyway some similitude present.

Banding pattern and some brightenesses, pôles as mentionned and at the limb of the planet.

The 16th image is performed after 3 full rotations of the planet atmosphere from the 4th report.

 

The 12th image:
