低空の金星はシーイングが悪いので夕方の早目の時間に撮ってみました。

Please find attached an observation of Venus made this afternoon.  Although the seeing was poor,the crescent was very obvious at x40.  There was some faint shading seen on the disk and the phase is around 18%.
Also:
Bright Limb Band: Visible and complete
Terminator: Geometrically regular
Cusp Caps:  The phase is now too small to see the cusp caps but both ends of the crescent were bright.
Cusp Collars: Phase too small to see them.

Here is a venus report using the 80mm refractor last 17th july.
Ashen light was there, level 1 intensity.
On the crescent:
some dark markings were noted, not interesting and corresponding to what a winjupos planisphere is showing.
On the dark side:
I tried to put the colors near the the terminator, an orange dark red  near the terminator, becoming greish towards the limb.
On the sketch, the dark side seems more illuminated than this was. The upper sketch represents, may be, the coloring at the eyepiece.
The limb of the dark side is not well delimited.
Some dark markings were noted. It seems more than this is drawn but their contours were vague, the markings sketched were delimited by a contour.
The ashen light extension was noted versus the color filter. The blue filter exhibited the less extension and intensity.
