150mm cassegrain.
I used the 3 possible way of observing, the O3 filter, R tricolor filter
and without filter.
The sketches are given as it was performed under an excellent pure sky
between clouds.
If you watch the dark side of Venus with a straight vision, planet on the
center of eyepiece, the eye at the center of the eyepiece, the result is
almost negative with and without an occulting dar installed at the focus of
the eyepiece. Without filter the ashen light is only suspected.
Under a slightly shifted vision, planet at the center of the eyepiece, but
the eye shifted slightly to the eyepiece center (as you can perform to see
a faint comet better), the sketches show was was captured with and without
the occulting bar installed in the eyepiece.
I leave you the present report for your perusal.
The features was more conspiscious without filter, after the O3 and the R
filter at the end.
With the O3 filter, there was as it seemed a disymetry of brightness
between the polar area.
