This image of the Orion Nebula shows several stars that exhibit the microlens diffraction pattern with a QHY163M, most notably is the brighter star towards the lower right of the frame.
There is also some ringing artefacts around the stars. I've estimated them to be the "out of focus" version of the star at about 0.6mm of defocus. This means it's a reflection half that distance so 0.3mm or the glass cover slip over the sensor.
