Composition of shots referring to the partial lunar eclipse in order to draw the edge of the shadow at the beginning, center and end of the contact. In the external images the Moon was in the advanced penumbra. Note how the brightness has changed due to atmospheric absorption.

Sirius C?

Viewing some "superframes" of Sirius, I noticed the appearance of a point source in the same direction as Sirius B, the famous white dwarf companion of the star that was originally the main star of the system.
I remember having glimpsed this source, which I called C, also in other videos captured in the past years in one or two frames. Unfortunately some videos were lost with the HD failure in 2017.
I can say, with some confidence, that it is not an artifact but must really be a stellar source very close to the star Sirius A visible at times due to the seeing. This does not mean that the star is part of the system but, more likely, it is just aligned perspectively and much further away. I found it without a doubt in five frames out of 250.
It is also possible that in the past years the object was occulted and is now emerging due to the fast proper motion of the system.
I invite anyone who has captured videos of Sirio at a good focal length (at least 3000mm) to check it out.
