Congratulations Ron!
Duchesnea indica or Potentilla indica--different genus from the true strawberry--originally from Asia, now invasive in the US.
I have had a go at stacking, this is a Photoshop stack of 10 images if a through-focus series. The key seemed to be a very tight series of photos with very small differences in level of focus--barely touching the lens, I can see why folks who do it a lot use a slider with a micrometer screw.
