Is that Seirios B?
In one of the last nights I tried to observe Seirios B. I'm not convinced if I was successful, so I ask you. The observation was made at 421x with a 24" dobsonian. Orientation is west = right, north = bottom. By comparing the orbit of the companion from diagrams in the www with my sketch, I might have been successful... In the sketch, the suspected companion is marked with the red arrow
I apologize for the image quality - it's only a photo taken with my cell phone...
