Nice one Andy, that's good going
This may sound a bit rich coming from me, but #1 may be a little over sharpened as it looks like the edges of details having "ringing". The prominent edge is a bit weird, although I can't really explain it. I've had the reverse problem before where the edge of the disc has bright noise but not clean cut-off such as that.
#2 looks good, but the details are more prominent in #1 IMO
#3 is classic less-good-seeing-syndrome. What a difference a week can make
I've not yet cracked the streaky moon problem...
