I put this together thinking it would be a good way to compare the apparent sizes of the four big objects that can be closer to the center of the Solar System than Earth. Obviously, the Moon can be a bit bigger (totality) and the Sun varies some, too. For the composite at bottom, I overlaid a Mercury image, lining up the solar disk, with a Venus image and then cut a hole in the Venus image where Mercury was. The Venus image was with a Coronado PST and the Mercury image with a Lunt 60. The Mercury image was taken with an ASI 174MM. I think the Venus image was with an Imaging Source DMK618.
