It was a dusty evening and 12P/Pons-Brooks was already low in the Northwest. Sky was not really dark too at this time in March looking to West. But the picture was a great surprise after some processing.
Just at 20h38 ISS passed by in the Northwest. And with good eyes one can find Andromeda Galaxy in the upper right, Triangle Galaxy below middle left and Pons-Brooks at the bottem.
