I have seen Sirius B many times this Winter with the 4" f/13 Carton achro. It is much easier to catch it at twilight...

Another Carton 4" f/13 user here. Even at 18 degrees altitude, I have been able to observe the Pup on quite
a regular basis over the last few months.

Interesting observations! I split Rigel easily with my Chinese 102ED F/7 the other night, but, at least at 100x, had no such luck with Sirius. I'll have to try higher power when my skies can handle it, and maybe pull out my AT80ED. Can't hurt to have more options on the table. No long refractors for me; I'm a newt guy who likes the eyepiece comfortably placed. 712mm of focal length is about all I'll own for a scope with the wrong end pointed down. Hopefully one of these will work. But there's always 2014 and 2015 if they can't seem to do it in 2013.

Brandon in TN, thanks for the twilight hint. I'll have to attack the Dog Star immediately after chasing down PANSTARRS next week.
