MR, you are amazing at how fast your photos have been improving. Who needs a jeweler's loupe when they can take photos like those and enlarge them. Better than a jeweler's loupe.
Now try what Anne posted about pulling back a bit from the subject, so you will have a larger area of focus. I tried that a few days ago. I was amazed at how the entire colony of semps seemed to be in focus. Not just one or two of the rosettes.
