Better to be around the BBQ this weekend with friends than investigating photographs
Moved some photographs over and added a couple more.
Dark formation above and to the right of Luna 20 Thing posted above.
Another formation to the right of bright crater in same locale below.
Here is another photograph of Luna 20 below. What is unclear is its orientation (inverted or not).
All things being equal to the other photo strips of Luna 20, another dark formation is above and to the left of Luna 20 in top right corner of photo below.
Below is the crater that I believe you all were considering as a possible crash site for Luna 18 as well. In the photo strip it is below Luna 20.
Quite a few targets to consider.
