Astrophotography by mistake photographing Venus and the Plieades

I'm learning Astrophotography mostly by trying many things making mistakes and learning from mistakes.  April 4, 2020 - trying to set infinity focus - by varying focus of a bright object, in this case Venus -  as I pass through the focus many dim objects appear and when they are brightest _ I think that is the infinity focus point 9about 400 light year - big infinity.  the Plieades above and to the right of Venus appear but I did not recognize - but took several image - while post processing, I passed the image through nova.astrometry.net for annotation - tells me where I've aimed my camera lens. labeled a number of the stars and other galactic objects, nebulae etc.

I first thought this a bee an later realized its the smallest hoverfly I've ever encountered.  never hovered only hopped from one cblossom to another
