Seaing Into Humboldtianum
image by Jocelyn Serot, France
You were mentioning yesterday that few lunar images were submitted these days.
You're right; the weather conditions have been awful for these past weeks.
The rare clear nights are spoiled by a very bad seeing.
It's a pity because the waxing Moon is very high at this period of the year in the evening sky.
And the nights are long - if cold.
Who said astronomy is a school for patience?
Attached is an image that i've managed to take on Dec 28, 2012.
I had to select 200 images out of 5000 and resort to IR-pass filter to get a decent image on this evening. And even with this, most of my AVIs ended up in the trash.
Anyway, this is a kind of view i specially appreciate, with grazing light on the extreme limb..
Unfortunately, I could not find the name of the buried crater in M. Humboldtianum in the 21st Century Atlas.. nor in the VMA. Is it named ?

Note from CAW:Thanks, Jocelyn for a hard-won image! The authoritative source for nomenclature is the IAU Gazetteer of Planetary Nomenclature, and looking at chart 15 shows that VMA and the 21st Century Atlas are correct - the crater has no designation.
