In full darkness it was not as easy to see, but I am satisfied now that it can be detected in a 4"scope. Again the "ghost" images that Sirius can invoke may trick many into thinking they have seen this little B. I had the ghost image sitting about 20" north of the the star while I made this observation. You can easily shift this image to get it out of the way, but I found the closer I had Sirius to the centre of field, the closer this image got towards Sirius. It also appeared like an 8th mag star, but much sharper and clearer than the companion.

Congrats - good to know it's worth perservering with. I'll have to try again with the 4" f15. What magnification were you using?
