Details:
Having done 3 photographic detections of Sirius B over the years (2012, 2016, 2021), I wondered if a composite image of the three could trace part of the orbit. This is the result. Many technical complications to work through given that the detections involved different setups (especially the 2012 one). 2016 & 2021: f/10 SC11, ZWO 120mm-s, 3X barlow, Hex Mask, SharpCap. 2012: f/10 SC8,Neximage with "LE mod", 3X barlow, K3CCDtools.
