I have the pleasure to transmit you some observations performed last 29th
with 2 scopes a 100mm achromat and a 120ED semi apo chineese.
Venus exhibits its polar caps as clear to bright surrounded by a dark
collar band.
Except this the general pattern noted remains usual with no specific event
collected with the present means.
The vision was altered by the presence of high altitude cyrrus clouds
making for the 100mm observation period more difficult as they appear
deeper for masking features on planet in comparison with the 120ED.
Anyway,the results are clear:
the 120ED exhibited more contrasty features in white light,substantially
less contrasty in red and blue channels than those noted with the 100mm.
It is strange to note such phenomena with an ED scope for which the results
would be better theorically.
I had no time for verification of what was appearing with a W11 filter in
the 120ED for making comparison with observations done in white light.

Even with the sun on the horizon and strong turbulence, only allowed me to witness the stage but without any details.
