Andrew,
Dave Finnigan has a really spectacular image of Mare Marginis from 2023 which features Jansky. It’s a fairly hard crater to image. I’ve taken the liberty of making an animated gif of Dave’s image to show which crater is Jansky. I would contact Dave and see if he is happy for you to use it.

You could also email Tony Cook, the Lunar Section Director and see if he has any images of it in the BAA archives. I will add this crater to my list of things to try and observe.
Good luck with the talk.
James
