Here is the Venus report for 28th done at the 200mm cassegrain.
AL was there against a pure blue sky with good images on calm times.
78-160 and 215x were used,best wth 160x.
Few markings on the Crescent was noted with very fine ones.
On dark side some dark markings were also noted as shown〓.
Not a big AL intensity but obvious and less strong than in 2013.
Survey is continuing,will try to set the dark markings on dark side next times with acuracy
The colored drawing is here for having an overall impression of the event,light intensity scale being not respected indeed.

Some experiments with the further addition of a Baader Neodymium filter to the stacking are proving effective in cutting through the sun-bright haze of a milky sky (thin cirrocumulus cloud); especially with blue fiters..
