Two days ago, while admiring the Moon in my 110mm f/15 refractor, I noticed two obvious domes. I made a quick drawing of this interesting area which I afterwords identified as domes near crater Arago:

Then I have learn from Rückl atlas that there are 4 more smaller domes in the area. These are probably two darker patches in the north part of the sketch. Also, I had a feeling that there is very hard to notice rille going from Arago almost to the crater Sosigenes A (the one on the north-western corner). Though it was very difficult to see it, as it was very thin, it was quite dark. However it seems from the atlas and also from images of the area that this was just a ridge (as on the eastern side of Arago where the ridges was forming the west edge of buried crater Lamont). This was definitely very interesting area.

Very nice sketch!

Just last month I tried to image the domes around the first quarter moon. My computer went out due to a hard drive issue.

I reached into my pocket and pulled out my iPhone and captured them and labeled the domes in Irfvanview free photo software.

Keep in mind the phone was simply hand held.
