I just watched the recent “Sky at Night” about the moon. On the program, Pete Lawrence challenged us to observe various lunar features. The hardest of these was Reiner Gamma, a lunar “swirl” (https://en.wikipedia.org/wiki/Reiner_Gamma)
That caused me to re-examine the window-sill lunar images I posted some months ago, and in particular the one of the 22-day moon.
So here is the same image with Reiner Gamma brought out. The joys of digital astronomy when clouded out! (and window-sill astronomy!)
