Here is a report performed with the R102mm under average good images on best〓moments and operated under a very transparent sky. No bright spot.
AL was more than suspected with the polar filter and no filter, full dark side, as shown,〓 with 67/95x magnifications, planet height〓53°, also with a yellowish tint well noted near the terminator and away. Cusp extension was evaluated to〓be more suspected at south and north〓on dark side.
South cusp extension〓was the brightest as shown.
Dark markings on the AL light was there.
The light intensity on dark side was degrading from〓terminator〓towards the dark side limb, full extension with the polar filter and without, at 67/95x magnifications, the intensity was not reaching a L1 〓(3 the highest) .
Turning the polar filter by 90° extincted〓the light level to a reduced level intensity and extension〓to more then half of the dark side, so not null, the variation of light remained〓subtil but well noted.
It was surprising to note the complete disappearance of AL between 9H26UT and 9H45UT, the evaluation with color filters was retaken after this time with intensity similar to the observation of 9H15UT.
