l  sometimes observed  twilight  Venus  during  this  autumn,winter  using  my  porteble  6"  D&G  refractor  on  a  wooden  tripod  all  hommade  in  1999....320mm fixed  refractor  was  not  possible  to  see  this  west  tilt  planet. 

About  15-20  times  observed  where  l  always saw a  ilusive  mottled  features  on  the  planet  at  x336.

l  think  Venus  is  the  most  beautiful  planet  to  see  with  naked  eyes  or  even  in  telescopes  because 

this  planet  appears  at  dusk  with  Earth  landscape . 


Pastel  colour  on  a  paper  is  hard  to  represent  its  beauty  though  l  attempted  here.

Is the flaring  secondary chromatic aberration?

Looks like atmospheric dispersion... Nice sketch! waytogo.gif

I think honnest your report performed with a 6" achromat.

Color aberration is well rendered with some chromatic dispersion by the atmosphere in addition.

Moltened soft contrasted features are there and realistic for sure, seeing must be fight for the collection.

The dark side of the planet seemed lighted.

I observed such with the 4" F7 refractor equipped with colored filters very recently.

However using the occulter, Nothing was actually there, also with a color free design, a mak 130mm without the occulter.

I think it's too early to capture eventually such before the quadrature, but this Survey is needed.

May I suggest you the use of colored filters in order to catch the banding pattern, this reduces strongly the color aberration and enhance the contrast level of features '(the deep blue W38A, the green W58, the red W29 for the most and the W11 yellow-green). The W11 is making similar reports done without filter.

Good skies.

Wonderfully illustrated detail in those illusive cloud tops, and a nice pastel sketch too. waytogo.gif

I really like this sketch. The diffused terminator, the soft limb banding, and vague mottling are nicely represented. But the “flaring” effect is an excellent touch!
