Here is a report performed with the CC154mm under average images on best¬moments and operated under a transparent sky.
A sign of cloud pattern was collected with some difficulty,boths cap¬not conspiscious¬clear,¬caps being probably faded by the planet tilt axis and more by planet phase,no bright spot.
AL was more than suspected with the R,YG,B,not full dark side as shown (dot line as limit) and with polar filter exhibiting the full dark side,¬ with 57x magnification,planet heigth¬32‹,also with¬ a faint light yellowish blue tint well noted just near the terminator. Cusp extension was not evaluated.
Some dark markings on the AL light was there (as drawn carefully,the same for each filter in use).
The light intensity on dark side was degrading from¬terminator¬towards the dark side limb,partial extension with the YG,R/B filters,¬ using polar filter on full dark side extention,but the intensity was reaching a L1 ¬(3 the highest) .
Turning the polar filter by 90‹ extincted¬the light level to a reduced level,but not null,as already reported on 15th,16th,17th and 18th,the variation of light remained¬subtil but well noted,its extention¬limited to the dot line on the dark side.¬
At the best angle for the max transmission,extention¬was full dark side with the collected dark markings.¬
Using the 74x magnification the AL light filled fully the dark side sothat¬the occulter test was tried as reported. Dark markings on the un-occulted dark side were the same,dark marking were absent on the background sky around the planet.
AL light intensity is not growing since days,reaching L1 level on the 23rd april,the maximum observed,here as intense than this 23rd april,the polar filter giving the more discriminatable¬light on the dark side when rotated at the best angle with full dark side extention,and dark markings presence.
The light intensity faded after 9H00UT,the polar filter kept in place but after also researching still the best angle.

The planet is now 7% illuminated and even the terminator shading is becoming hard to see.
Bright Limb Band: Visible and complete
Terminator: Geometrically regular.
Cusp Caps/Collars: Neither seen.
I did manage to observe Mercury but thin cloud appeared and obscured the planet before I could make a drawing.
