Success is sweet, I have seen the Pup!
Using a C8Edge & a Tak 6mm Ortho EP, I found it, a bit further from Sirius A than I was expecting. Using Delta Gemini as a guide worked well. Delta G is like a fainter Rigel, but the secondary's magnitude is similar to the Pup so gave me a much better idea of what to look for than does Rigel.
Thanks guys for all your tips!
