Here is a report performed with the CC154mm under average good images on best〓moments and operated under a very 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,B,WF,not full dark side and with polar filter also,only partial dark side with the YG filter with 74x magnifications,planet heigth〓39°,also with〓 a faint light yellowish blue tint well noted near the terminator. Cusp extension was not evaluated.
Some dark markings on the AL light was there (as drawn carefully).
The light intensity on dark side was degrading from〓terminator〓towards the dark side limb,full extension,using polar filter and R filter,〓 but the intensity not reached a L1 〓(3 the highest) . Turning the polar filter by 90° extincted〓the light level to an insignificant〓level.
AL light intensity is not growing since days,reaching L1 level on the 23rd april,the maximum observed,here less intense than the 13 and 14th may,the polar filter giving the more discriminatable〓light and the larger light extention〓on the dark side.
